Quarantine, SW, LR to avoid Crypt et al.  11/13/08
Greetings, I hope this message finds you well.
<Yes, thank you>
I read the excellent article about quarantine written by Anthony Calfo.
Unfortunately, I read it after I had already stocked my tank and come up with crypt resulting in a now fallow 120 gallon reef with the five remaining fish fully cured, but quarantined until my display tank has been empty for at least 42 days. I have learned my lesson!
<Good>
However, with regards to live rock, I just want to be sure that I fully understand what precautions need to be taken before introducing live rock from a very reputable fish store. Currently I have about 20 pounds of live rock purchased from two separate local fish stores. They are currently quarantined in a 20 gallon long aquarium that is in the process of cycling so that I will be able to eventually use it as a frag tank.
How long should I leave this rock in quarantine before placing it into a small "fish only" tank?
<A good question... as most all stores have little actual success in keeping "wet gear" isolated from their live rock tanks (if even on separate recirculating systems), it may well be prudent to isolate such new material for a few to several weeks... in the hope of rendering pathogens less virulent>
Thanks for the excellent information posted here.
Best regards,
Jeffrey Castaldo

Quarantine Tank Use 11/10/08
Hi
<Lori>
Thanks for the wonderful web site and allowing us the benefit of your knowledge. I really appreciate it.
<Thank you, happy it has helped.>
I have a couple questions about quarantining wet pets. Which is very sad considering that I have had a saltwater tank for almost 8 years and never quarantined anything before. I recently have done a lot of research and found out that I have been extremely lucky!
<If you have had no problems, then yes!>
I don't wish to tempt fate any longer, and decided that I need a qt tank.
<Smart move.>
I ordered a couple of items from a diver from Florida, I asked on a forum of my local reef club about quarantine. I was told that since this came directly from the diver and that he visually inspects each piece not to worry...then I found your web site, and another member wrote to quarantine everything.
<Direct from the diver means direct with any pathogens/parasites too.>
My order comes in on Tuesday 11/11. I have ordered a mixed lot (before I read), a yellow Atlantic tang, 10-15 polyp zoo frag and 2 emerald crabs.
<These crabs are opportunistic predators.>
Finally to my questions. I have read everything that I could find and am not sure if they would be okay to quarantine together.
<This can be done, but if something needs to be treated the protocols will be different. This is why you remove fish from the display for treatment. Also, just use ich as an example. If your fish end up with it you can remove the corals and treat the fish. But now you must treat the corals just as if they were in the display, with a quarantine/fallow period (they can host to mites). More on this here:
http://www.wetwebmedia.com/ichartmar.htm >
I would like to use a hypo salinity quarantine, will the crabs and zoos be able to handle the lower salinity, I know the zoos can handle freshwater dips, so I am assuming that they would be okay in lower salinity as long as they were properly acclimatized?
<No, not the case.>
Can I use carbon filtering up until/if I have to treat with medication or is it better to stick to sponge filter and 1% water changes daily?
<You can use carbon, but you will still need to monitor your water quality.>
If I treat the quarantine with copper I am aware that I will have to move the zoos but I would prefer to not have to buy another quarantine setup unless absolutely necessary.
<Be sure to remove the crabs also.>
Any information that you could give me would be greatly appreciated.  FYI Everything that goes into my tank from here on out will spend the mandatory 4 week minimum in quarantine. Also in all that I read I never found this, do you purchase a new sponge filter after each quarantine or wash the old one with freshwater?
<You can just wash it out, though if you treat with copper I would just go ahead and spend a few bucks, buy a separate sponge for invert quarantine.>
Thank you for your help
Lori

Velvet, fallow, inverts 11/07/2008
Hi Crew,
<<Joel>>
I made the mistake of buying three small Chromis from a LFS and adding them to a 12 gallon QT that already housed two large feather dusters and three large turbo snails. Two of the Chromis were dead within 24 hours from what I'm fairly certain was velvet based upon factors like rate of breathing, speed of onset, and the pictures I found online of infected fish. Moving the last one to a 3 gallon after a malachite green/formalin bath did nothing to save the poor guy/gal. So, I've left the 12 gallon QT fallow for almost 4
weeks. I plan to go 8 weeks total before moving the dusters and snails to the 55 gal /20 gal sump main display.
<<As this is only the quarantine tank, I don't see a need to send this fallow. Empty, wash out with a 50/50 white vinegar and water solution, recycle, and re-use. Move the feather dusters and snails to the main display tank.>>
But here's the pickle. I've been wanting a mated pair of purple firefish for awhile, and Liveaquaria.com suddenly has a pair in the Diver's Den. So I my question is about juggling. Would it be safe for the three turbos and the two dusters to move to a mere 3 gallon tank for their remaining QT of 8 weeks?
<<Not really acceptable, no, see above re moving them to the display tank now>>
Is that environment too small even for these inverts? If that's okay, then I'd be able to empty, bleach, and reset the 12 gallon QT for the firefish. I look forward to your thoughts. Thank you.
<<To sum up, move the inverts to the display tank now, strip, clean, re-cycle ready for the new fish. No problem with quarantining the two firefish in the tank as long as they are small specimens, but, keep a tight fitting lid. Inspect the specimens when you have received them, if there are no visibly signs of disease / injury, 4 - 5 weeks in QT is more than ample.>>
Regards,
Joel Pippin
<<Hope this helps. Regards, A Nixon>>

Re: Velvet, fallow, inverts - greater confusion. 11/11/08
Thanks for the reply, but I'm not sure I follow your logic.
<Hey Joel, Scott V. with you this go round. Reading over the original query it does appear there was an error in communication. Sorry for the tardy response.>
Per Bob and others, I QT everything. If Marine Velvet can live for up to 8 weeks without a host, then moving the dusters or the snails, which currently live in the water that might house latent MV, might introduce infected water into my main display
<Agreed.>
- my understanding is that even a few drops containing the organism is enough to quickly kill my tang. It seems you believe there is
no risk of this, and that does not gel with what I've read on WWW, hence my question about the 3 gallon QT for the inverts for a few more weeks.
Please check with Bob is possible and reconfirm that you believe there is no risk to my main display by moving these inverts after only four weeks since MV broke out in this QT.
<I would continue your QT for the full duration.>
Thanks,
Joel
<Very welcome, Scott V.>

Re: Velvet, fallow, inverts - greater confusion. 11/11/08
Thanks for the confirmation.
<My pleasure.>
If you also think the 3 gallon QT would work for the three snails and two feather dusters to finish out their time.
<Sure will, just be sure to feed.>
Regards,
Joel
<Welcome, Scott V.>

Should have QT, Read 11/7/08
Hey WWM,
You guys are always helpful to me when I have problems or questions about my aquariums.
<A pleasure to help out.>
I currently have a 55 gallon reef with 2 occ. clowns, flame angel, yellow tang, six line wrasse, hippo/blue tang, scarlet cleaner shrimp, bubble tip anemone and some coral, crabs and snails...not many on the clean up crew though...well I have multiple problems. First the LFS convinced me to buy a clown tang (which I love) for 30 bucks and I brought it home and the next day it was covered in ich. I put it in a QT with copper and it died.
<Not to mention the issue of three tangs in a 55!>
I knew I shouldn't have even brought this fish home since it's very difficult and my tank is way too small. The rest of my fish were doing perfect but since that clown tang my hippo now is covered in white spots and I noticed the flame angel and yellow tang had it also. I'm very worried I may lose more fish due to this mistake I made. What should I do about this problem?
<Set up a quarantine tank and treat them.>
Also within the past 3 months I have been getting terrible brown algae on my sandbed. When the lights come on its barely there but by the end of the day its everywhere. Its not cynao I know that, but I cant get rid of it.
<Same protocol as cyano.>
I changed out my sandbed a month ago with fresh sand and it worked for a week and now its back.
<The sand is not the issue, water quality is.>
I don't know where to turn for this but it's killing me. I have a AquaC remora skimmer, coral aqualight, magdrive with SCWD for water flow and a Eheim pro 2 for filter.
<Do be sure to clean the Eheim quite frequently.>
Also my bubble tip is doing really bad, very small and all white. I have reversed bleaching on a Sebae before but it doesn't seem to be working for this bubble tip.
<Two anemones are trouble, will not work in a 55.>
I feed it mysis shrimp every 3 days...thanks WWM for your help I really appreciate it!
Joe

Question about Firefish quarantine, 10/22/08
Hello WWMedia crew,
<Hi>
I read over the info about Firefish on your web-site and I know that you as a whole routinely recommend to quarantine fish in general.
<Yes>
However, a couple of times it was mentioned that a quarantine period may be detrimental to Firefish. I realize that it would be a risk to put any fish directly into the main tank; but in the case of Firefish, would it better for them to be placed directly into the DT?
<They can at times be difficult to feed and very shy in an overly sterile QT with good hiding places. Sometimes putting them directly into the DT where there are lots of bolt holes and microfauna to feed on helps, sometimes it introduces disease. Pluses and minuses to both approaches.>
Yesterday I purchased a paired couple of red Firefish. They were placed in a bare-bottom QT with PVC pipes, air stone/pump, an external filter and a good cover on the tank and I just use ambient light.
<Good, lots of PVC here helps a bunch.>
I routinely do 10% daily water changes and monitor parameters. They will be fed a combination of frozen Cyclops-eeze, frozen Mysis soaked in Selcon and Formula One Flakes.
<Good.>
My questions are: Do I keep going with the quarantine tank or move them to the DT?
<If you can get them to eat and they are not cowering in the corner of the tank I would go with the QT.>
For the Firefish, is a 2 week quarantine too short or should I do a minimum of 4 weeks?
(I routinely do a 6 week quarantine). I realize there is no right or wrong answer but I want to maximize the chances of survival for this couple.
<Generally if they adapt well to the QT initially you will have few problems going farther. The quietness of a QT can be very beneficial to this passive fish, gives them a chance to beef up a bit before going into the DT.>
A separate subject/question. I know that some people recommend adding garlic as an appetite stimulant. Do I just crush a small amount of a fresh garlic clove and soak the food with it?
<Can, although probably easier to buy a prepared liquid mixture available on-line and in most fish shops.>
Thank you in advance,
Miguel Perales

Methylene Blue - Is it safe for a QT tank?  9/27/08
Greetings WWM Crew,
<Mike>
After reading the articles and FAQs on Methylene blue (MB), I have a rather simple question:
Is MB safe to use in a SW QT tank?
<Very>
I have read conflicting information. The CMA and this website only mention its use in a FW dip, but I have read accounts of is being used when shipping fish. Other on-line resources state that MB is to be used in FW only.
<It's been a long time since I've seen Methylene Blue used in shipping marines... some folks, businesses do use it in freshwater applications... in both to reduce light penetration (calm the animals before being boxed) and improve DO>
I have a 55g QT tank, I use PVC piping to provide a shelter for the fish, and use about 0.25" of regular "play sand" for a substrate (It is disposable after QT is finished) 10 - 25% water changes are done daily. I use a canister filter for water filtration\movement, and a sponge filter for biological (kept in the sump between uses.)
I always give new acquisitions a FW dip with MB, followed by hypo-salinity (1.015 - 1.017) in the QT tank, slowly building it up to 1.025 near the end for the QT period.
I would like to add MB to the QT tank at least during the first few days, Partially for its mild antiseptic\oxygen carrying properties, and secondly because I have noticed that new fish settle down and adapt better if the water is "darker".
<Worth trying. I don't think there is much chance of any serious downside/s here>
Thank You,
Mike

Power-outage problems with fish in QT...   9/19/08
Ok, so i bought a yellow tang and a potters angel 2 weeks ago and had them in a quarantine tank until yesterday. Our power went out on Sunday, and luckily i had about 20g of water ready. We had a generator running to keep the QT tank and DT tank going. Well AEP said our power wouldn't be back until this coming Sunday and i ran out of water 2 days ago(we have a well so no running water when the powers out). Yesterday the ammonia was near 1ppm so I had a problem...
Let the fish suffer in a QT with no water changes for 4 more days or take a chance and add them to the DT. I chose so add them to the DT because i figured they would be better off. And they we both super healthy and eating everything i gave them.
<I would have done the same>
I added them yesterday and they seemed to be fine. They did spend a lot of time by the cleaner shrimp. Well the power came back on today and my yellow tang now has ick spots. He still eats like crazy and he doesn't seem to act funny..
should i let him go for a day or two to see if things get better?
<Yes, I would... even if you have a protozoan infestation, your system itself is now resident...>
I could see why there would be stress... high ammonia, temperature problems with brief power loss etc.
Other than the 2 fish i added yesterday i have a pair of black ocellaris clowns and a pair for Banggai cardinals.
If i do decide to QT all my fish and treat the ich, should i use copper (i have copper and a copper test kit) or hypo or what? I hear tangs and dwarf angels are iffy with both...
<I would likely opt to try establishing some sort of status quo here instead of treating... Please read here: http://wetwebmedia.com/parasittkfaq2.htm
and the linked files above... to the point where you understand the concept, rationale. Bob Fenner>

Acclimation after Quarantine 09/18/2008
Im sure I've overlooked this answer somewhere on the site. I am in the process of setting up a 55G reef that should be ready to go in about two months. My first tank was a 90G so this is a large downsizing for me.
Anyway, I didn't utilize a quarantine tank for my last reef and was very lucky not to have to many problems.
<<Very lucky indeed....heeee>>
However, im no longer in an apartment and now have some extra space for a 10G quarantine/hospital tank.
<<Superb>>
The question I have is about acclimation from the quarantine into the main tank. Since I would be using water from the display tank to fill the quarantine is acclimation still necessary? If so, am I to just float the bag and be very careful not to allow any water from the bag to spill into the tank?
<<Nope, no acclimatisation required, as you will of already acclimatised to the quarantine tank when you purchased the inhabitants. Once QT'd, simply net or tub the creature over to the display tank. Always best, as always, to keep the water from returning back to the display tank when the time arrives to move them>>
<<Hope this helps, A Nixon>>

Quarantine or no Quarantine – 09/12/08
I am purchasing a mystery wrasse, a trio of Resplendent Anthias, Pseudanthias pulcherrimus, and a Decorated Rabbitfish, Siganus puellus. I am purchasing them from live aquaria from their divers den selection.
http://www.liveaquaria.com/general/general.cfm?general_pagesid=425 (if the link is no good you can get to the page by going to live aquaria, then divers den, then look at a particular fish or coral and the link is on the right side of the page.) Should I quarantine these fish if they have gone through this quarantine process already?
<Mmm, not the Anthias IMO, the others I'd take a look at on arrival>
How can I be sure their QT was effective?
<IS a good company, good practices, but "things" can/do "get away" with the best...>
They will eventually go to my 90 gallon display with 70 pounds of live rock
<Do make some "cave" arrangement for the Siganid, others to get out of the light>
a shallow sand bed and a 25 gallon sump/refugium with a miracle mud bed covered by sand and an AquaC EV 180 skimmer. I am removing a 260 watt pc light that is failing and I will be adding new lighting to the tank 2 250 watt Icecap HQI lights with 15000k XM bulbs. The current fish in the tank are 3 Ocellaris Clownfish, a Yellow Tang, a Sailfin Tang,
<Mmm, do watch this fish for dominance issues, with growth...>
Royal Gramma Basslet, a Sailfin/Algae Blenny (Salarias fasciatus) and a Mithrax Crab, and a variety of hermit crabs and snails. So Should I quarantine?
<Your call... I would run the Labrid and Rabbitfish through a prophylactic dip/bath at least, enroute to the main display>
My QT tank is a 20 gallon with 12 pounds of live rock a sand bed several corals and a skimmer Coralife Super Skimmer 65 and 130 watt pc light. The 20 gallon was getting set up to be a qt or grow tank for corals but I only have a few specimens in the tank. Should I set up a simpler QT with a ten gallon if this QT is not appropriate?
<Mmm, maybe... Good to have an extra tank about... for this and that purposes>
I though it may be a good to QT so I can make sure the Anthias are eating but I don't want to stress them out either.
<Yes... these fish are best placed straight away... in the main display>
I appreciate your opinions and advice. If you gave any other opinions, observations or recommendations for my success in taking care of my new fish, or current fish, please let me know? Also I have been looking for Sweetwater zooplankton and I can't find it anywhere. Could you point me in the right direction?
<Keep that curious mind, and continue your lifelong researching (is what I have done). Bob Fenner>

Quarantine tank, more... reading  9/9/08
Dear crew,
I have a 90 gallon reef tank which unfortunately got contaminated with marine velvet. We lost 2/3 of our fish, and we had to start a quarantine tank from scratch. Now it is finally approaching one month that the reef tank has been free of fish, and we are trying to get a game plan for restocking the tank this time. Our quarantine tank has never completely cycled, so we had to do 25-50% water changes every other day
<Quite common situation... Usual practice>
and we still have nitrites around 1
<Yikes! Deadly toxic>
and nitrates around 10, but very little ammonia. We kept adding Seachem Prime and Stability, and we did 2 wks of copper.
<Mmmm>
Once we move the remaining fish to the reef tank, I was told that we should completely strip down our quarantine tank and start over. I was also told that we can cycle our quarantine tank quicker by increasing the temp to 85 degrees and not putting any fish in it.
<Double Mmmmm>
I was wondering if we need to do this so there is no chance for any remaining marine velvet
<... you need to read re Amyloodinium... trtmt...>
in the quarantine tank
<? No>
or if this would cycle the tank quicker.
<The temp. yes... see WWM re cycling period...>
We are anxious to put fish back into our reef tank, but I know we don't want to rush things. How long do you need to put a new healthy fish in a quarantine tank?
<... posted...>
and do you need to treat a healthy fish with copper or any other med? I also have one true percula clown left and we want to add another clownfish. Does it have to be another true percula or can it be a false percula and should it be bigger or smaller?
Thanks again,
<Please learn to/use the search tool, indices on WWM. Your answers and much more that is lacking in your present, needed consciousness is archived there. Bob Fenner>

Lack of quarantine, Retail  -09/02/08
Hello team
<Emma>
Please accept my apologies, but I feel I need the advice of people who are experts in the field of marine aquatics. I understand that this email is not the average email topic you would receive, but I adore your site, and love your no nonsense approach.
<We are glad... we share!>
I have worked for the past three months in a large pet store. We have started to sell marine life, which is all very exciting. However, when the new section of the store was built, the owners did not take into account that the livestock may become ill, so have not provided any means of quarantine. I find this absolutely appalling. Fish have been dying needlessly since the get-go. A beautiful French Angel, who has had a bacterial infection for the past week, is now dying needlessly as there is no where to treat it. My managers are not helpful, they seem content to net out their little bodies when they die. Myself and a colleague set of one tank a few weeks ago which we used as a hospital tank, but the manager flushed it through yesterday rendering it useless.
<Mmmm>
Please help me convince them that we need a quarantine bay. I understand you are very busy, but I hold this very close to my heart, and it is soul destroying watching these beautiful animals die. Do you have any thoughts on how I can best get my point across? I have problems expressing myself, and your advice would be so greatly appreciated.
Thank you
Emma
<Please have these folks, the owners, managers contact me re this issue. In all my writings for the trade, presentations made for the industry touching on livestock, I have endeavoured to impress on folks the absolute need for such facilities, their appropriate use... NOT only for the sake of the livestock, but simply on economic principle. I would refer them to our archives in Aquatics Business: http://wetwebmedia.com/AqBizSubWebIndex/Biz%20Index/Biz%20index.htm

Re: Lack of quarantine, Ostraciids now  -09/02/08
Thanks you, Bob - I shall certainly do that!
<Good>
One more question if I may? We have 3 bays of 9 tanks (so 27 tanks in total). Each bay is centrally filtered. Last week, they bought 2 yellow boxfish, and placed them into their own little tank in the bay, next to a rather expensive Mimic Tang among other things. Would you say it is safe to keep the Boxfish in a bay sharing water with the other fish? I have nightmares about them dying and wiping out the whole lot!
Thanks again
Emma
<Mmm, Boxfishes can be deadly toxic to most all fish life, in a surprisingly large volume of water... but if care is taken to not "shake them up" (in handling, being stocked with aggressive tankmates) or not fail to see them die, dissolve... they can be placed in with other fish species.

A quick question..., Quarantine 8/4/08
Greetings:
<Hello>
I have a 100 gallon reef aquarium which is slowly being stocked. My question concerns quarantine practices.
<Ok>
The tank contains only a few fish and that is how it will remain. All have been quarantined for a 4 week period prior to their being added to the aquarium.
<Good>
Whenever I acquire a new invert, whether it be a coral, snail crab or clam it goes directly into the tank. How risky is this to the health of the fish? What are the chances of an invert harboring a fish specific parasite cyst? So far there have been no problems but I have to wonder.
<There is definitely a chance to introduce certain parasites to the tank doing this. While I cannot give you a percentage number as to the risk, we definitely have gotten more than a few queries regarding Ich introduced by non-fish means. I recommend QTing anything wet for 4 weeks as well to try to limit this risk.>
Thanks.
<Welcome>
<Chris>

Re: A quick question..., Quarantine 8/4/08
Hi Chris:
<Hello>
Your response brings up another question. The reef aquarium set-up is optimal. Lighting, filtration, circulation and water quality are all up to spec. My quarantine tank lacks most of these parameters. No metal halides, no skimmer. Although I can maintain the water quality in an invert quarantine tank, I cannot guarantee enough algae to feed a snail or enough
light to keep clams and corals happy. Can these animals survive 4 weeks of less than optimal conditions?
Thanks again.
<For the most part if healthy coming in they can survive just fine in a QT. Snails and crabs can be fed algae wafers or shrimp pellets to supplement them. If you are planning on adding many coral specimens it may be worth investing in decent PC setup to help them along. Also supplemental feeding can help as well. It can be problematic as you say but with a little work it is doable and safer for your existing livestock.>
<Chris>

Ich and inverts? 6/17/08
Morning Crew :D
<Hello>
This may sound like a strange question, but is it possible to introduce Ich (or any other parasite/disease) into a reef tank on invertebrates such as clams, shrimp or corals?
<Oh yes.>
Knowing how susceptible these are to copper I'm assuming a QT would be used here, in which case what would the procedure be, i.e. would the usual 4-5 week quarantine period be enough or too much?
<Would be just about right, as long as you do not QT it with fish of course.>
What signs would you need to look for?
<Nothing you can see really, just time for the potential parasites to complete a lifecycle without fish.>
Many thanks again for all your help and for such a great resource,
Carolyn
<Welcome>

Ammonia in QT 05/10/2008
Hello WWM crew.
<<Hello, Andrew this evening>>
First, I would like to think you for all your great work. I have used your site extensively over the last three years however this is
the first time I have written in.
<<Thanks for the comments, and nice to hear from you>>
I searched though your site and on the internet but I couldn't find the answer to my question. I recently set up a 10g QT system for my 29g reef. I have never done a QT before but you guys convinced me. Here is the QT setup: a pinguine biowheel HOB filter without the biowheel ( I think it is a 50g model but I'm not sure), A 50w stealth heater, two 14 watt 6500K CF bulbs screwed into the hood that comes with the tank, and a 4 inch PVC tee for cover. I left a sponge in my sump for about two weeks prior to setting up the system and put the sponge on the HOB intake. I used 1/2 tank water and 1/2 SSW to start with. I feed about 1/4 of a cube of cyclops each day and vacuum the bottom about an hour later. The system has been setup for 7 days. I originally had a 1 inch PJ cardinal.
<<Sounds fine so far>>
On the fourth day the QT was set up in my main tank, my 1.5 inch ocelaris clown decided my 7 inch Dersa clam would make a great host.
<<These fish never cease to amaze me in what they choose as a host>>
This hosting really bothered the clam and he kept shutting and his mantel wouldn't extend. I decided to put the clown into the QT to let the clam recover which he did immediately. I plan on selling the clam since he has grown much to large for my tank. In two years he grew from 2 to 7 inches!
<<Very good growth indeed>>
On the day I added the clown, I did a 50% water change using water from my main tank. I have been testing the ammonia with the API test kit and it has been very close to zero maybe around .07 until today, day 7. It is now between .0 and .25. I would guess the level is around .15. The two fish are acting normally and show no signs of disease. The PH is 8.2 and the temperature is 79 degrees. Today I added a few pieces of grape caulerpa hoping it would absorb some ammonia.
<<Sounds fine to me>>
These are my questions. 1) is this level of ammonia ok? I noticed you recommend water changes when levels near 1 but what about lower levels?
<<Yes, its fine>>
I found a study that said 48hr LD50 in Atlantic silversides was in the 1.5 range but I'm not keeping Atlantic silversides! 2) should I do water changes
with new SSW or old tank water? I use RO/DI with a TDS of 0 and IO salt.
<<New saltwater>>
3)what would be the maximum stocking density for a QT this size?
<<What you currently have it at>>
4) Do I count 21 days from when I added the PJ or the clown?
<<From when the cardinal was added>>
It seems I don't need start the QT over if I added a healthy animal from my main tank. 5) Should I add LR from my main system and if the fish do get sick will I need to boil this rock?
<<No, PVC pipework is more than adequate for the quarantine tank>>
6)Should I stop feeding the tank?
<<Feeding every other day should suffice>>
7)On an unrelated note, could I keep a very small 1-2in yellow or blue tang if I take him back to the LFS when he gets 2+ inches and if now what could I keep in my tank that eats grape Caulerpa? (total water vol is 45 gallons with a 10g fuge).
<<I would not, no, sorry to say>>
Thank you so much in advance!
<<Thanks for the questions, I hope this helps. A Nixon>>

Anorexic Butterflies & QT process--Correction  4/7/08
Hello again,
Realized the Second main paragraph might not make sense, It should have  read in part as follows: Sorry for the confusion.
...The QT is monitored for ammonia twice daily, and has registered .25 mg/l at 24 hours, .5 at 48 hours and .75 at 70 hours.
<To degrees toxic at all concentrations>
The QT is treated with a dose of Prime (according to label to bind ammonia of .6mg/l at 24 hours and 45 hours and a double dose at about 64 hours.
<Mmm... okay>
The fish are removed with as little extra water as possible (plastic clear container, no net) at under 72 hours...
<Good technique. Will have to look for whoever responded previously (did they?)... but in reviewing your prev. email, this looks like a solid protocol/plan. BobF.>
Hello,
Thank you for your site, it has been a wealth of information for new saltwater fish hobbyists such as myself.
I have two questions, one as relates to your comments on my quarantine process, and two as relates to non-eating butterfly fish.
I purchased the following from Saltwaterfish.com. They arrived 7 days ago, and were drip acclimated over 2-3 hours and placed into a 17 gal quarantine tank made up of water transferred from my main tank:
parameters 1.023, PH 8.15, Temp 78, Ammonia Zero, Nitrates between 0 and 2.5. The quarantine tank (QT) is bare bottomed, has a few colored hard plastic cups for hiding, dark construction paper on three sides and the bottom, and has a hang on filter with ammonia absorbing pad. The new arrivals include a 3.5 inch Pearlscale Butterfly, a 3 inch Punctato Butterfly, a 2.5 inch (was expecting it to be between 3 and 4 inches) Pakistani Butterfly, a 3 inch thin Dragon Goby
<I'd summarily move this animal and get it solid, high-protein food-feeding ASAP>
and a 1 inch Skunk Cleaner Shrimp.
The QT was treated with 500 mg Chloroquine diphosphate fully dissolved before fish placement. The QT is monitored for ammonia twice daily, and has registered .25 mg/l at 24 hours, .5 at 48 hours and .75 at 36 hours. The QT is treated with a dose of Prime (according to label to bind ammonia of .6mg/l at 24 hours and 45 hours and a double dose at about 30 hours. The fish are removed with as little extra water as possible (plastic clear container, no net) at under 36 hours and transferred to a new QT with the same parameters from main tank (new dose of Chloroquine and all). Filter, tanks and reusable objects in the tank are treated in dilute bleach, then rinsed, then soaked in prime treated water and dried before reuse. Overhead light only on for short time before, during and after feeding attempts for observation and feeding. This new QT tank rotation has been repeated three times so far. My thinking on this was to remove with a high degree of confidence any Velvet, White Ich or Black Ich present on the fish before entrance to main tank. (This was used successfully with a pair of Heniochus Butterflies a few months previously, one of which arrived with two white dots on its fins about 0.5 mm size, which disappeared from the fish between day 3 and 5 of QT and has not showed back up after transfer to main tank.) Do you see any weak link in this plan?
Second question involves the fish themselves. The Pearlscale arrived with many black dots on its side, as of day 7 in QT3, they are all gone, and it appears to be very healthy -- has been eating everything I offer including Formula Two pellets. It is mildly pushy with the Punctato, but appears to ignore the Pakistani. The Dragon Goby, which arrived thin but with no lesions noted so far, has filled out with good feeding and is doing great also. The Pakistani arrived with one 0.6 mm white dot on its rear fin and pectoral fin and two fuzzy 1 mm white lesions on lower fin edge. As of day 7, only the white fin edge lesions remain.
The Pakistani has not been eating. It ate 2 Mysis offered 20 hours or so after arrival, and 2 live brine shrimp offered day 6 in the a.m (in QT2). and 2-3 more offered that p.m.(in QT3) The Punctato arrived with no lesions, is swimming just fine, but has only eaten 1-2 Mysis offered on that first day. I have tried the following so far over the last 7 days: Mysis offered at least every other day, Formula Two pellets, fresh clam on the half shell, fresh mussel in shell (diced up), diced squid, a seafood medley of shrimp/whitefish/Nori/clam all slenderized and lastly live brine shrimp. The Pearlscale and Goby are in heaven and will eat everything offered, but the Pakistani and Punctato are fasting. I have tried a few drops of fresh squeezed garlic water and also Entice by Seachem. (I have been unable to find Selcon, which I see recommended on your site, anywhere locally). The Punctato goes crazy swimming rapidly around the tank with the Entice, but does not eat.
Neither Pakistani nor Punctato have any mouth lesions that I can see.
The Pakistani frequently goes and sits with its sides near the Cleaner Shrimp, did stare at the clam shell put in the tank, has rubbed its gill/side area intermittently on a few shells added on day 7 and its gill rate is more rapid than the other fish, but does not appear in distress. Unless I see anything else problematic, my plan is to move the Pearlscale, Dragon Goby and Cleaner Shrimp to the main tank at day 9 since they appear healthy and their presence may be affecting the two anorexic ones; and move the Pakistani and Punctato into a new 10 Gal QT treated with 250 mg Metronidazole and not move them to main tank till eating and well. Do you have any other feeding or treatment suggestions?
<Mmm, just to move all along expeditiously... through this process and to your main system in a minimum of time... with live rock et al. there>
Am I right to think that if they are not eating in the QT, they are unlikely to eat in the main tank?
<Mmm, no... much more likely to commence feeding in the main display>
Thanks for comments on my QT process and suggestions on feeding anorexic Butterfly fish.
Joe
<The non-feeding... due to collection, handling stress, isolation in small, bare settings is par for this course... Finish the quarantine and move them. B>

Quarantine absolutely every thing! 3-24-08
Hi Bob
<<Hi Jen, BobF is out for a few weeks so I’ll be filling in for him on this query.>>
I've been a silent fan/visitor of WetWebMedia for years and have learnt so much from you but I still make terrible mistakes from time to time.
<<Eh...who doesn’t?>>
I have your book and counted myself a reasonable fish keeper but boy was I wrong! I had a yellow tang 7 years, a harlequin tusk 6 years and a blue face angel 4 1/2 years and I have just killed them all by my stupidity! I want to warn others that you just MUST quarantine EVERYTHING you want to put in your tank!!
<<A good warning that I hope other hobbyists will take under serious consideration and I apologize that you had to learn the hard way, though I am glad you did learned it.>>
I always quarantine fish and corals because of what I have learned from you but I made the fatal mistake of putting 2 pieces of live rock in my tank plus some plant life into my sump to lower nitrates. This alone has been enough to introduce disease into my tank. All 3 of my precious fish have succumbed to what I think is Cryptocaryon irritans (white spot) but might be Amyloodinium.
<<Mmm…do see our FAQS/articles on WWM re disease on this, so that you get perform a proper diagnosis in the future.>>
I’m not sure, does it matter as they are all dead now and buried together in my garden. I am having nightmares about these fish because I know I killed them when. You already warn to quarantine everything but success very often breeds contempt!
<<Agreed.>>
If this saves just one fish from this awful death then it will have been worthwhile. I know this might sound over the top but the longer you keep a fish alive the harder it is to lose it especially when it’s your own fault!
<<Again Jen, I am sorry you had to learn the lesson this way but I applaud you for your open mind and thank you for sharing this anecdote with us.>>

Disease Question…How Long To Hold In Quarantine “After” Lymphocystis? – 03/19/08
Hey guys and gals-
<<Hey, Jay…Eric here this AM>>
I hope all is well with the crew.
<<Haven’t heard otherwise, so will assume so…thanks>>
I just have a quick question about cauliflower, (Lymphocystis). I adopted a Sailfin tang with cauliflower about 45 days ago from a pet store.
<<I see>>
She went straight into a Bio Cube aquarium for quarantine and has, (thanks to aggressive water changes and proper nutrition), made a complete recovery, (no more 'polyps').
<<Very good…and often all that is needed>>
I have treated many fish before (Ich and what-not), but this is my first cauliflower case.
<<You seem to have done well with it>>
Everything that I have read says that treatment is quarantine, time and good water quality (that I knew already), but I can't find any info on how long she needs to be in a QT.
<<Hmm…>>
How long should she stay in quarantine -after the spots are gone- before I can put her into my main tank?
<<A good question… Considering this malady is thought to be only very slightly (if at all) infectious; and the root cause is environmental (poor water quality/diet), this fish could be removed from quarantine and added/returned to a healthy and properly fed display tank within a few days of “clearing up”…though you might want to consider giving it a week to “just be sure” the fish’s immune system has indeed recovered>>
She has been clear for about 10 days now.
<<Should be plenty of time, in my opinion>>
Thanks!
-Jay
<<Happy to share. EricR>>

Chaetodontoplus personifer in quarantine, hlth.  02/27/2008
Hello WWM Crew,
<<G'Morning, Andrew today>>
Let me just say that I love your site and read over the new FAQs several times a week but this time I couldn't find anything similar to my situation.
<<Lets cure your lust for knowledge>>
The other day I walked into a LFS and spotted 2 very small (1" and 1.5") personifer angels for only $28! I asked them to hold the slightly larger one for me and went home and set up a 10 gallon quarantine tank. On the first day he seemed fine but mostly hid in a large plastic coral. On the second day he was swimming about normally and ate some frozen food. On the third morning I woke to discover him "breaching" at the top of the tank and swimming erratically. Soon after he just lay on the floor of the tank looking washed out and breathing heavily. I immediately performed a 30% water change and dosed the tank with triple-sulfur. 2 hours later he was fine, swimming normally and feeding again. 2 more days have passed and he is feeding well and behaving normally. I have been changing 10L of water each day, should I do anything more to help this little guy out? What would have caused his strange behaviour? I couldn't see any sign of external parasites. Could it have been Ammonia poisoning from the uncycled quarantine tank?
<<Yikes.....Yes, certainly...A quarantine is basically just a miniature marine system, and as such, should always be cycled. The point that the fish changed for the better after the water change shows that the behaviour is due to this uncycled tank. For future, what you could do is keep the filter media from the QT filter in the main display tank as this will cycle the media and keep it in this state. So, you'll always end up with an instantly cycled quarantine tank. In your current situation, you need to closely monitor water parameters and keep the water changes flowing>>
Any advice you can give me would be greatly appreciated.
Yours Sincerely, Adam Harbeck
<<Thanks for the questions, hope the above helps. A Nixon>>

Re: Chaetodontoplus personifer in quarantine 03/19/2008
Hello Andrew,
<<Hello again Adam>>
I submitted a question a few weeks ago about a tiny Chaetodontoplus personifer I purchased on the 22nd of Feb and now I have a follow up query. The fish has been in quarantine for 25 days now with a water temperature of 28C, is eating very well and has grown about 0.25cm. As suggested I have been performing frequent water changes (10l/day).
<<sounds good>>
The other day I noticed a small white spot on the back of his right pectoral fin. I kind of panicked and performed a pH adjusted freshwater bath on him and dosed the tank with triple sulphur. He took the bath very well, just lay on the floor breathing normally patiently waiting for his 5 minutes to be up, but the spot remains. I have encountered whitespot in the past but the fish looked like they had been dusted with white pepper, scratched incessantly, stopped eating and hid. The behaviour of this fish hasn't changed at all, his colours are still bright, i haven't seen him scratch once, still eats like a pig and spends his day displaying to himself in the glass or coming up to beg for a feed when I enter the room. I have not been adding more triple sulfur to the tank during changes because I am afraid of poisoning him, I have been told that angels are very sensitive to medications.
<<indeed...Is this the only spot? Continue to monitor in the quarantine tank>>
I think by now the concentration would be very low. Should I leave him be for a couple more weeks to see how he goes? Or should I give him another bath with some Methylene blue added and add him to the main tank? I have grown quite fond of the little guy and would hate to lose him now. Any advice would be greatly appreciated.
<<Continue to monitor the spot in the QT tank, if this is indeed white spot, then hypo would be the next step to eradicate the ich>>
Yours Sincerely .. Adam Harbeck
<<hope this helps. A Nixon>>

Re: Large Angelfish et. al... QT method...  – 03/07/08
Thank you.
One final question. I assume I should be QTing one fish per tank?
I have a 37 gallon tank that I would like to QT a pair of Golden butterflies, but do not know if this is an acceptable practice.
thanks

Should I keep treating? SW Quarantine...  2/29/08
Hi everyone,
<Melissa>
Thanks for the great work with the site. I spend hours reading each day. I have a question about a possible bacterial infection. About a week ago I purchased 5 blue-green Chromis and a Sixline Wrasse. After a freshwater and Methylene Blue dip they were placed in quarantine. The next day all fish were eating well, although I did notice one Chromis hanging out near the top away from the group. The next day a different Chromis had some red spots (I thought it may have been from netting and shipping).
<Likely so>
This developed into his tail rotting, discoloration, missing scales and cottony material in the area. I thought it might have been a fungal or bacterial infection and started to treat with Pimafix.
<...>
The next day he died and I noticed the Chromis that had been hanging out near the top had stopped eating and his tail was starting to rot and he also had red spots. I did some research on your site and after a 50% water change, decided to treat with Jungle Fungus Eliminator (at double dose).
<Mmmmmm>
The second Chromis died today. The remaining three have no visible spots, are swimming and eating well. The Sixline, however, stopped eating today (before medication was added). He doesn't show any other symptoms, but since this was the first the others displayed I am wondering if I should keep treating and for how long.
<I would not use either one of the products you mention>
Also, would you recommend daily water changes before adding the next dose and if so, what percentage?
<I would monitor ammonia, nitrite... change if either becomes appreciable. See here: http://wetwebmedia.com/mardisindex.htm
the files on Quarantine...>
My last question is, after this is cleared up I would like to replace the two Chromis that have died. Would you recommend extending the stay for the three that are left and adding the new two to the quarantine with them or should I move the current three fish out, quarantine the new Chromis and add later (I wasn't sure if this would cause problems with bullying or acclimation to the group).
<I would do the latter>
Thanks for you help!
Melissa
<Welcome! And good that you isolated the new Chromis. Bob Fenner>

Re: Quarantine, methods    2/24/08
Hey Bob, Todd again
Everything's going great now, thanks to your insight and WWM!!! I've learned a lot from you (fish stuff and English!! Haha!!) and with months of reading on your web site!!! I'm on it at least once a day!!!
<Me too!>
I have 2 clowns, blue tang, purple tang, copper band and 4 neon gobies in my 120 gallon, and everyone looks and are doing great!! I dip everyone in a freshwater/formalin dip for about 10 minutes (1 ounce 37% formalin to 5 gallons water), and then quarantine for 40 days, and then same dip before main display. Everything's been going great so far, I haven't seen any diseases in the quarantine tank or in the main display. But I'm sure eventually I will end up with something a some point in time that I will have to deal with!!
<Let's try to avoid>
So for the future, say I end up with itch or velvet in my quarantine and I need to treat with copper or formalin for 40 days. I know you don't recommend formalin for long periods of time, but for the copper sensitive fish what else is there that's guarantied to work?
<Posted>
In all that I have read when using copper or formalin is that they will kill the biofilter and all the nitrifying bacteria in the tank and that the protein skimmer (because it sucks up the meds) should be removed from the quarantine tank. So in that case should all filtration just be removed when using copper or formalin, because its not going to do anything anyways?
<Mmm, no... is of some use>
Is there anything else I can do to keep the ammonia down besides water changes, light feeding and vacuuming everything I see out of the tank, I have a 30 gallon quarantine and if a 6" fish becomes sick and I have to treat it say with copper, I'll probably have to do like 100% water changes once a day. What do you do in this situation and you have to treat with copper or formalin for a 40 day period?
<Water changes...>
You think it would make that big of a difference with keeping the ammonia in check if I had say a 100 gallon quarantine with just power heads and air stones and no filtration for treating with copper or formalin for 40 days?
<Mmm, not much... better to have the 100 gallons in water for change outs...>
I'm going to start adding some inverts soon and in your book you suggest using iodine for dipping corals before quarantine, is iodine ok for SPS, LPSs, soft corals, mushrooms, zoo's, polyps and Featherdusters?
<Yes>
Is there any other dip or anything that I can add to the 40 day fishless quarantine to help these guys get rid of the bad guys?
<Slightly lowered (a thousandth perhaps) spg. to aid in absorption>
Besides setting them off of the bottom and picking anything I see off of them or out of the aquarium.
Also can I use the iodine on crabs, shrimp, stars and snails before quarantine? And besides iodine (if you even can) and 40 day fishless quarantine, is there any other dips or anything that I can add to the 40 day quarantine to help these cleaner crew guys out?
Thanks again Bob for your time and insight!!!!!! You've been a great help!!!!!
<Welcome. BobF>

Algae control and quarantine  2-10-08
Dear WetWebMedia Email Answerers,
<Mike here>
We have had our tank (set-up below) for almost 3 months. We have been reading your site the whole time and thank you for the time you have spent providing information.
<Sure thing - this website is an excellent source of info>
We recently purchased Drs. Calfo's and Fenner's book - Reef Invertebrates.
<I have an autographed copy ;)>
We love the book and have learned a great deal from it. We believe we have the information we need to move forward, but we would like to clarify a few things first. Here is our tank set-up:
55 gallon
38 lbs of live rock
60 lbs of sand
2 maxi-jet 1200 powerheads
Fluval 305 filter
We are planning to purchase a protein skimmer today.
<A skimmer is highly recommended. So is more water flow, and make sure the laminar flows from the powerheads and returns are pointed to produce as much random turbulent flow as possible>
Livestock:
6 Nassarius snails
2 Astrea snails
2 turbo snails
3 blue-legged hermit crabs
1 red-legged hermit crab
2 emerald green hermit crabs
1 fire blood shrimp
1 cleaner shrimp
1 spotted mandarin fish
2 maroon clownfish
1 rose bubble tip anemone
<That mandarin is going to slowly starve with the little live rock you have in your tank. I would immediately work on a refugium, and try to get the mandarin eating prepared foods. I would also purchase copepods as a supplement - I've used www.Reed-Mariculture.com in the past with excellent service>
The tank did not get any livestock for about 1 month. Then we started to add the Nassarius snails, Astrea snails, and crabs (not all at once - a little at a time). Fish and shrimp and anemone were just added about 2 weeks ago.
The turbo snails were added a week ago. Our plan is for few fish, mostly invertebrates (corals, 1 clam, starfish? - not sure on that one having read the Invertebrates book).
<Educate yourself regarding the lighting/feeding of (I assume) Tridacnid spp. before purchasing>
All of our water checks have been good, including checks for phosphates. We have it checked at the store, but are purchasing our own test kit today.
<What is "good"? Numbers are always encouraged when sending us questions. You should have already purchased a complete set of test kits, but better late than never>
All is going well and everyone is getting along well. Our biggest problem is algae. We have a fair amount of what we think is green algae. It looks like the picture of Chlorodesmis in the Invertebrates book. If it is this, we understand it is good, but we don't want it to fill the tank and it is spreading. We also have brown hair alga on the back tank wall and a small amount of Cyanobacteria. We have been removing the Cyanobacteria as best we can using a suction tube when we do water changes. We had been doing them about monthly, but plan to start doing them more often (1/week or so).
<Nuisance alga is *always* an indicator of excessive dissolved organics and usually lack of water motion, as well>
Problem 1: Algae - We know this comes with a new tank. We think the protein skimmer will help. We think more often water changes will help.
<Yes, and yes. Don't be afraid to perform large water changes every week - I tend to perform 50% water changes/week in every marine aquarium I've owned - just make sure the fresh saltwater is the same temp/pH/salinity, and well mixed/aerated>
Question 1: Our filter has 3 carbon sacs we change with the water 1x/month.
Can we change 1 sac at a time and do it more often (1x/week)? Will that help with algae?
<Quality carbon should last at least a month after the cycle is complete - Seachem Matrix carbon is great if you want a recommendation>
Question 2: We are considering getting a kole or chevron tang to help with the green algae. Is the tank large enough for him with 3 other fish?
<This aquarium is really too small for any tang species>
It seems he will eat the green algae and mysis shrimp. We feed our clownfish defrosted mysis shrimp (alternating plain with some that have Spirulina mixed in). Will that be ok for him or will he need something else?
Question 3: Kind of related to algae - what is the best method for straining the frozen food to get the water out? Our feeding routine is: we defrost 1 cube of food in a small amount of tank water (in a small container) and pour out as much water as we can. Then we feed 1/2 of the food and refrigerate the other 1/2 until the next day. We feed with a turkey baster. We supplement our anemone and shrimp with small pieces of krill (1-2x/week).
<Pour through a kitchen strainer or piece of cloth>
Problem 2: Quarantine - We know we should quarantine the fish for 21+ days.
Question 1: What should we feed the kole tang while in quarantine?
<Don't purchase a tang>
If he eats algae off live rock, and live rock can not be in quarantine, how do we proceed?
Question 2: We already have a small (10 gal) tank set-up with some live rock, a sponge filter, air tank, no sand, but some detritus and PVC small pipes. Some of the live rock will go to the main tank in a few weeks to 1 month, after it has cured a bit. The main purpose of the tank is that we are trying to grow some copepods for the main tank. It has only been set-up for 1 week (using water from our last water change). We know fish can not be quarantined in this tank with the live rock. But would this be a good tank for quarantining the coral? Or will that cause a problem with the water/rock in there?
<I wouldn't use LR in a quarantine tank at all, turn it into a refugium instead, and set up a separate system for QT>
Question 3: Would a second similar set-up (to the one above) be good for a fish quarantine?
<Yes>
Question 4: Do we put copper in the water with the fish in quarantine even if the fish is not showing any symptoms? Or is it ok to just treat if we see problems?
<Preventative treatment with a less stressful medicine such as methylene blue would be fine, but I would never representatively treat with copper>
Thank you for your time. Please let me know if I have not been clear about something.
<I was lenient with you because you are new to the hobby, but the answers to all of your questions could have been found with more perusal of our archives. Do take the time to educate yourself with the resources available here>
Sincerely,

Quarantine Procedure  1/25/08
Hi,
<Hey there! Scott F. with you, on the road again...>
Thanks for the quick response on my canister filter question. I would like to bother you with one last query. When using a fresh water dip for a new fish before going into the quarantine tank should methylene blue or any other medication be used in the dip if there are no visible problems.
Again, thanking you in advance
Shawn
<Well, Shawn, it is certainly possible to use medications or additives in freshwater dips. I have typically employed methylene blue in prophylactic dips, and I know other hobbyists who use medicated freshwater dips (using agents such as Formalin) for disease treatment (for specific conditions, such as Ich, etc. In general, I would not use a medication as a prophylactic, unless I was treating for a specific disease. Far better to employ a straight freshwater dip, with or without an agent such as methylene blue, and then release the fish into a dedicated quarantine system. I'm happy to hear that you are embracing a quarantine protocol. It's so easy to do- and has such a beneficial impact on your overall hobby success. Best of luck to you! Regards, Scott F.>

 

QT Procedures and Ich Treatment 12/4/07
I have a 75 gal tank that I recently set up about 2 months ago. I am new to this part of fish keeping, although had cared for freshwater for 8 years. I now know I should have quarantined my fish before putting them in my tank.
<Yep>
I put a sixline wrasse, blenny, firefish, coral beauty, two percula clowns, and a pajama cardinal in at first.
<Too much too fast here, need to slow down the stocking.>
They all seemed fine until I put a yellow tang in. He also looked good until after a week, when I noticed white spots. At this time I started doing some research, and found this great sight. My two clowns have come up with a few spots and that is it, the rest look fine.
<Are still infected most likely.>
I have quarantined my tang, but am wondering how I should go about treating them. I only have a 10 gal QT which is entirely too small for all these fish. I cant afford another one at this time.
<Perhaps a large Rubbermaid food-grade container would be more budget friendly.>
Would it be as effective to take my live rock and inverts out and place them in my QT for about 4 weeks while I treat my display tank with copper, or is it only effect to remove fish, treat them with copper and let main tank fallow for 6-8 wks.
<The latter, copper can be difficult to remove from an aquarium, and your substrate would have to be removed also. More problems here than its worth. Best bet is to figure out a way to house all fish outside the main tank.>
Also I was wondering if you recommend a UV sterilizer? I have one but many hobbyist have told me that they kill more beneficial organisms than bad. What is your opinion?
<I don't think they are terribly effective in most cases, they need just the right flow rate and contact time to really work and most are not able to provide that. Also they are not capable of curing most things alone, and treatment is still necessary. As far as doing more harm than good, this I do not agree with, I don't see much downside to them, although their upside is limited as well.>
I hope your holidays are great, and
thanks for any feedback

Re: QT Procedures and Ich Treatment 12/4/07
Chris,
<Hello>
Thanks for your great advice.
<Welcome, although probably not that great.>
Ok right now I am treating with kick-ick, have you heard of this?
<Yes, 5-nitroimidazoles, I do not believe it to be terribly effective.>
It seems to be working, although I know the parasites come and go anyways.
<Most likely just it's lifecycle.>
Should I continue treating with this reef/invert safe treatment, and if at 3 weeks time they are still present, then should I treat with Copper, or should I just do that right away.
<I would discontinue its use and set up a proper QT tank. The problem here is that the clowns and tang are sensitive to copper, I may use formalin here instead.>
How long do you suggest leaving my fish in a FW dip with Meth Blue (10 Minutes)?
<As long as they don't freak out too bad this should be ok.>
The other question I have is one of my beloved Percula Clowns has a white blister looking thing below his lip that he developed about two days ago. Is this a fungus, or possibly just from scratching.
<Could be a bacterial infection due to some physical trauma, fungus is pretty rare in the salt water side of the hobby.>
How can I tell, and if it is a fungus, whats the best way to treat this.
<Right now I would not use any additional treatment due to the ich medication, good water quality and appropriate food is the best course here.>
Can he be treated with other fish?
<For ich, yes.>
The last question of this e-mail is when setting up my QT should I use water from my display tank, being its cycled,
<Water does not really cycle, that occurs on solid surfaces.>
or just use RO water and change water weekly while it cycles.
<Probably will need daily water changes, and you can start with either, the ich treatment will make it irrelevant.>
Thanks so much again.
<Welcome, and check out these FAQs and related articles for more.

Re: QT Procedures and Ich Treatment 12/5/07
Chris, I just want to thank you again.
<Welcome>
This really is not a question, but I just want to make sure I have this right. Ok so this is how I go about treating my fish with ick, correct? First I get two QT tanks set up with proper parameters for my load of fish. Then I catch the fish, giving them a FW dip in Meth Blue. At this time I put them in the QT tank. In this tank I treat one tank with copper (Cupramine) and the other with containing more sensitive fish (tang and clowns) with Formalin (Rid Ick+). I do this for two weeks while at same time raising temperature to about 82 degrees and lowering SG to about 1.019.
<Leave the SG at normal levels, 1.019 is not low enough to help eradicate the ich, but low enough to stress the fish, normal levels are better here.>
After two weeks I should begin to bring back these levels back to normal.
Then let fish sit and be observed for the next 4-6 weeks while my display tank continues to complete fallowing for a total of 6-8 weeks.
At this time do another PH adjusted FW dip with Meth Blue before introducing fish to display tank. I hope I have this right, cause I have read about every article on this over past few days, lol.
<Seems like you got it.>
Do you think a 10 gal tank to house a yellow tang (small) and two Percula clowns, and a 20 gallon tank to house a firefish, pajama cardinal, lawnmower blenny, coral beauty, and sixline wrasse would be too much for bio-load if I do a 10% water change with RO water daily?
<Should be for this time frame, just make sure to have plenty of hiding spots for them (PVC pipe works well).>
The last question is while I'm catching these fish will it be alright to take LR out and place on towel for that time, or will the time in air kill the live bacteria?
<Should be no problem.>
Thanks much,
Evert.
<Seems like you have a good plan here.>

Quarantine Question, Marine Ich 11/29/07
Hi crew,
<Hello>
I have a question concerning quarantine procedure. I have all my fishes including a purple tang in hospital for ich. I am dosing with Coppersafe at 5ml per 4 gallons of water.
<Careful treating Tangs with copper, they generally do not handle it well.>
I plan to keep this up for 4 weeks. How can I be sure that my fishes are ich free at the end of the QT period?
<Keep them in QT for at least 4 weeks after the treatment is finished, most likely ich would show itself before then.>
I understand ich can still be in the gills even if it isn't visible on the fish. If my fishes are not scratching and there are no visible signs of ich for 4 weeks can we say that ich is eradicated?
<Not for sure, but is most likely the case.>
I am asking because this is my third time fighting this parasite in the last 6 months. I attribute my past failed attempts to improper QT procedure.
<The most common cause.>
I have since made some improvements including keeping all equipment and supplies dedicated to QT and testing and maintaining copper levels. Oh, and can you tell me if it is at all possible to eradicate ich completely from tangs?
<Can be done, the problem is that copper treatments are not tolerated well by tangs so other methods need to be used.>
I have heard opinions to the contrary and need to hear it from WWM. Thanks a lot!
<With proper procedures it can be done.>

Dwarf Angel Fin Rot, quarantine methods f'  – 11/17/07
Hello,
<Greg>
I am fighting a losing battle with a case of fin rot on a dwarf angelfish in a 10 gallon Q/T. The fish did fine in Q/T for about 10 days but then started getting ragged fins.
<Maybe simply the quarantine experience>
The fins were just literally disintegrating a small amount each day. I started treating with Kanamycin (SeaChem Kanaplex) every 48 hours, but after 3 days the fins continue to erode at a faster rate. The fish is eating fine
<A very good sign>
and all water parameters look good as I have a full biological filter which is surviving the Kanamycin treatment. Ammonia and nitrite are zero 3 days into treatment. I did go without chemical filtration for about a week. But once the fin rot started, I filtered with carbon and PolyFilter for about 1/2 day and did a 25% water change before starting the Kanamycin. I am concerned the Kanamycin is not working and I am wasting valuable time to save the fish. Should I continue with the Kanamycin and if so for how long? Or should I switch to a different antibiotic for fin rot? At
a loss here as I have used Kanamycin successfully for fin rot before.
Thanks,
Greg
<I would discontinue the Kanamycin, not try other antibiotics... I would summarily pH adjust and freshwater dip and place this animal in the main display. Please see here and the linked files above for the thinking/rationale here: http://wetwebmedia.com/dips_baths.htm
Further quarantining will not likely grant you anything... other than a more-stressed specimen. The root cause of the "rot" is likely non-pathogenic. Bob Fenner>

Melafix in the main tank, Improper QT methods 10/23/07
Hello,
<Hi>
I have a 125 gallon FOWLR. Specifics on the tank are: 6in live DSB, about 100lbs of live rock, and 2 sumps (a 20 gallon and a 30 gallon). The 30 gallon contains a refugium with live sand, live rock, macro algae and a orange spotted goby. The 20 gallon houses my protein skimmer in one chamber and a return pump in the other. Water from the refugium drains into the return pump chamber. Current inhabitants of the main tank include: 1 tiger wardi goby, 1 juvenile Koran angel, 1 powder brown tang, & many Nassarius snails. The tang was the most recent addition, after a quarantine period of two plus weeks in the refugium.
<Not a good way to do it. QTing a fish is as much for the protection of the current residents as much as the new addition. Needs to be in a completely separate system, otherwise disease will be transferred between the refugium and the main tank.>
Soon after I put the tang in, one of the angel's eye became puffy and cloudy. The tang seems to be brushing against the sand more now that he is in the main tank.
<Water quality? Any other signs of possible parasite infection?>
Do you recommend treating the entire system with Melafix?
<I never recommend treating the main tank with anything, and Melafix is pretty worthless anyways. These fish need to be removed to a separate hospital tank if they need to be treated for something.>
The manufacturer states that the product is reef safe but I am not sure if anything in the refugium will be affected.
<Very well may, and the product will not help the fish either.>
My second question is, given my livestock and system, would you recommend me adding a flying gurnard in the future?
<No, see here http://www.wetwebmedia.com/flyinggurnardfaqs.htm for details.>
Thank you for your time and advice.

Quarantine Procedures 10/16/07
Hello
<Hi>
Love the site, the best I've come across by far!!!!
<Thanks>
I have a few questions I was wondering if you could clear up for me?
<Will try>
I learned my lesson not having a quarantine tank, but I now have one and my 120 G has been going fallow for about two months now (bad case of the ick), I think I might let it go till Dec before I add fish just to make sure!!! (You think its worth the wait or is 2 months good?)
<8 weeks should be fine.>
I was told by the LFS that ick came go dormant, if so how long would you need to wait to add fish to the infected tank?
<Its lifecycle is abut 4 weeks, with no host they will die.
http://www.wetwebmedia.com/ichartmar.htm >
And also if I wanted to use some of my supplies (test tubes, buckets, gravity testers etc.) between my quarantine tank and my two other tanks. What's the sure best sure way to kill everything by disinfecting? I've heard hot water, should I run hot water over and through the pieces or submerge in bucket, if so how long is good to kill everything.
<Needs to dry completely as well, while hot water is probably enough in most cases I would not be comfortable using this method alone.>
And I've also heard of using bleach, should I be submerging in bucket also, and also how long to kill everything?
<This is the better way, submerge for a few hours, rinse well, let it dry completely. Treating it with dechlorinator after is not a bad idea either.>
I just would rather not have to buy 3 sets of equipment if I don't have to.
<Better to have separate equipment, otherwise 1 mistake and you have reinfected your tank.>
When is the best time for my freshwater dips, when I first get the fish before quarantine or after quarantine right before I put fish in main display?
<Before QT>
Or should I be doing both??
<Could>
During quarantine should I be treating with copper or other meds even if I do not see any problems?
<No, only treat when necessary.>
If so what do you recommend? I know meds are not always healthy for the fish. But the reason I ask is that I have read that fish can be infected with ick etc., but not show any symptoms until stressed.
<They will most likely show signs in a QT tank if closely watched.>
In that case couldn't you quarantine a fish for 30 days and not see any symptoms, put in main display and then pass lets say ick to a more prone weaker fish and have the nightmare start all over?
<Yes, but most likely would show signs before introduction.>
And a liverock question. On my reef tanks I've always ran my compacts for 10 to 12 hours and my halides for 4 to 5 hours in the middle of my compact lighting. On my FOWLR 120 G I have 2-175 14K halides, I don't ever really plan on having any coral or any thing in there, I just like the look of the shimmer effect and the color of the halides, But I do want to have alot of nice coralline algae to grow and cover the rock. What's the minimum time I can have my halides on to get the coralline growth can I get away with 4 to 5 hours a day or do I need them on for 10 to 12 hours for that coralline growth?
<Coralline will grow in most any light.>
And last of all a fish question. Is there any kind of coral, polyp, urchin, invert etc. or anything non fish that you can put in with Triggers, Puffers, and Eels? I figure no but I thought I'd ask while I had you.
<Not much these fish will not sample.>
Thanks so much for the info,
Danielle
<Welcome>
<Chris>

Re: Quarantine Procedures, Identification, Coralline Growth 10/16/07
Hello again, thanks for all the info!!! One more question for you, kind of a weird one, I have never read about this one anywhere.
<Fire away>
When I had that last ick case I had a yellow tang that was the last fish to die and I didn't get him out of the tank right away because he died deep into all the live rock, a week or two later I noticed alot of things growing on the black walls of the tank, down the overflow chamber, in the sump and on some of the live rock, not so much on the front clear wall. If I would have counted them there would? have been? probably 200 to 300 of them, they were everywhere. They looked like 1/4" to 1/2" white magnets or sacks, most of them standing long ways outward from glass or rock, and on the outward end away from glass or rock had kind of a flower looking end with like 6 to 7 skinny petals or fingers, kind of like a flower duster with fewer fingers and not as full. They don't move at all sitting there or when they are touched, just sway a little in the current. I stripped down the whole tank and got rid of 99% of them, but I have just noticed a few? on the live rock here and there. Do you know what they are? How to get rid of them? Is it safe to add a fish with them?
<Tough to guess from that description, maybe Aiptasia or a Hydrozoans. Whatever they are they were their population most likely grew due to the nutrients released as the tang decomposed. I would guess it is safe to add fish but impossible to be sure depending on what they are.>
And in reference to coralline growth question earlier, will the coralline growth be quicker and cover more of the rock with the light on for?10 to 12 compared to 4 to 5 hours?
<The longer usually the more growth, although different colors of coralline grown at different rates depending on light amount and wavelength.>
Thanks again for all the info and the great website!!!!!!!!!!!!!!

Analysis of Fish death in QT... You read it and tell me   10/12/07
O boy. I've lost 2 fish (French angel and a royal Gramma) I've been keeping in QT and basically I'm curious as to why and how to prevent this from happening again
Here are some of the facts :
I'm keeping them in a large red plastic bucket (around 15-20 gallon).
<Heated, filtered? Recirculated? Treated in some way?>
Both fish HAS been eating up to 8 hours before perishing.
<Have...>
Temp has been fine fluxing a few degrees at max.
<Fahrenheit? In how much time?>
pH was 8 (on Salifert) and 8.3ish on aquarium pharmaceutical ph test.
I've been having to add a LOT of pH buffer (the Kent 8.3) daily (at least 1/2 a scoop morning and evening) <-- is this normal?
<To add this much or buffer period? I would NOT do this... such changes should be made gradually, through changed-out water that has been modified ahead of use>
The pH over the week in the tub drops to 7.7ish nightly (off API ph test)
<Good that you're checking>
Salinity I was lowering from 1.02 to 1.014 over 2 days.. and was about to lower it again to 1.010 the morning after discovery of death.
<... Am not a fan of such hyposalinity "treatments">
Ammonia/Nitrite/ undetectable (tetra test) Nitrate was "orange" so was about ~25ppm
<Too high... but likely to be expected under/with the circumstances>
I've also been dousing the tub with one of those chlorine/ammonia removing chemicals when I did the small water changes.
---
The French angelfish showed some sign of Ick with a few spots and cloudy fins (hence the low salinity) 5 days before death.
<Again...>
I FW dipped him for 5 minutes and when I placed him back into the tank.. he "nearly" died.
<... cumulative stress>
That night he lost his balance and let the current blow him against the rocks while upside down. The only thing I found wrong was the pH.. was so I added some buffer. Miraculously the next day he was OK and would eat the following day out of my hand (mostly formula 1/2) U can bet I was really happy.
The morning before death he showed a more severe ick infection... but oddly they were GONE in the afternoon.
<Cycled off...>
The Gramma was hiding so I let him be. (??? what happened I didn't treat him at all that day)
------
so that is the "history of the fish" ... but I managed to catch them in their deaths late at night.
2 hours before death the French would skulk near my powerhead/quick filter apparatus (instead of hiding in the PVC tubing). First problem I thought was pH but the readings were fine. I added 1/2 a teaspoon of buffer regardless (as I didn't trust API's accuracy)
What was bad news was that my royal Gramma came out of hiding to the powerhead/quick filter as well.
As they died .. the French angel was breathing hard 80+breath per min (I could not tell if my royal Gramma's pace was extra-high). I have both an aerator and a 402 Hagen pump in a 15-20 gallon bucket so I thought there should be decent circulation + oxygen.
The royal Gramma VERY oddly had one last "spaz-out" before he died.
Swimming to the top very quickly and changing it's direction randomly for a few seconds. After that, he was a goner. When I examined the bodies... there was NO sign of velvet/ick.. and that one of the royal Gramma's gill flap was open 45 degrees so that I could see his fleshy gill (red but looked normal to me)
---
So after reading that long post... can ANYONE tell me what caused them to die.. and how to prevent death in the future.
<... these fishes died from a combination of poor water quality, changing circumstances and protozoan infestation... You need to read... re Cryptocaryon... environmental manipulation for disease treatment... and how to select specimens period. Bob Fenner>

QT Tank question, treatments   9/7/07
Hi Bob,
Due to the recent loss of my Bellus Angel to a nasty form of Ick, I've taken your advice and set-up the 55 gallon tank to be fallow for the next three months. It's got a few hermits crabs, snails, pieces of live rock and sand left in it. Raised the temperature to 82 and lowered salinity to 1.019 which I'll lower more over time. I'm running the skimmer, filter, power heads and doing regular maintenance on it.
<Okay>
Also set-up a 10 gallon QT tank as prescribed in your web-site. In it I have two pieces of PVC pipe, a bio-wheel filter and air stone running. (The only thing in the bio-filter is a few of the bio-balls taken from my 150 tank). I used 5 gallons of the water from my 150 tank and 5 gallons of freshly made saltwater to get started. I'm keeping the tank running at 78 degrees and 1.020 salinity which I'm moving down slowly. The inhabitants in this tank are one small lawnmower blenny (1 inch) and two yellow-headed gobies (3 inches).
<All right...>
As they were in the 55 gallon tank with the sick Bellus, I am treating them with Quinine Sulfate as Formalin-3 didn't seem to help the Bellus.
<Is very close to cure or kill...>
I am feeding them then removing any leftover food and waste immediately with a turkey baster. Also doing 25% water changes every other day. My ammonia levels are running at .50. Is this okay as it seems the best I can do?
<Mmm, yes>
If not, should I add filter media that removes ammonia?
<No... will/would likely remove the Quinine>
I've already read that you find Amquel a weak alternative.
Also, my LFS said that the gobies should do fine without having any substrate to sift though. Sound like a good response to you?
<Yes... for treatment>
Thank you,
Gregory E. Esposito
<Let's hope your earnest plans work out fine here Greg. Life to you. BobF>

Hippos... Quarantine? – 08/17/07
Just a quick question... in Bob's book as well as on your website, it is suggested to place Hippo Tangs directly into the main display without quarantine to reduce the stress of multiple catch and release out of quarantine. Are you still of this opinion? In my past experience, a Hippo I had about 4yrs ago seemed to be a 'Crypt' magnet.
<Mmm, Paracanthurus are not "as bad" as such compared with many other Surgeonfish species... and my opinion is "it depends"... "IF" the specimen looks otherwise in good health, it can be isolated for a time... to assess its health... However, it can be peremptorily FW dipped and placed in most cases>
Would u expect a Hippo Tang, aside from adding nice colors to a tank,
assist in mowing done some green hair algae?
<Depends on the species of algae... not many are palatable... and many that look "Green" are not... are often BGA, which is entirely undesired>
I will be adding a Foxface after a 4 week quarantine which I'm thinking will further assist
in a green grassy hair algae problem. Note, the tank is 200gallons FOWLR.

Buddy System Technique in QT – 06/29/07
Dear Bob and Crew,
<Mike>
I did my homework, but was unable to find a clear answer or opinion on the following.
A question regarding the quarantining process, if you don't mind.
<Not at all>
I have noticed when quarantining my fish as I work through my stocking plan, that these fish all seemed miserable and stressed while in my QT, and not just for the first day or two.
<Not atypical>
It is a 10gal., 8-10lbs LR forming a tunnel / hideout, 1/2" Reef Sand, hang on filter with BioWheel (very quiet), and only half lit (which is not often - I use the room lights and dimmer when needed)
Temp 76, PH 8.2, No measurable signs of ammonia, nitrites or nitrates
Clowns just swam up and down in the same corner. They never even made it to the other end of a 10gal QT??
<Happens>
The Coral Beauty just hid underneath a rock completely out of sight the whole time. The Pixie Hawkfish would always run and hide, and always seemed nervous or skittish. (Not all fish at the same time, mind you)
All "seemed" (and I am not a marine psychologist) generally stressed and unhappy, IMO. ("IMO" - now that's proof that I've been reading WWM)
<An honest assessment, expression>
All of the above immediately seemed fine right after being moved to the main 72gal tank with LR, Reef Sand and a cleaning crew including a (Lysmata?) Fire Shrimp.
I have been watching their relationship with this shrimp in the main tank and became curious.
I am now quarantining an approx. 3" Longnose Butterfly in my QT and have tried something different this time. (Yes, I probably should have asked first)
I put another Fire Shrimp in my QT along with the Butterfly to see if it might make a difference in aiding the new addition in feeling less stressed while in this 10gal for a couple of weeks.
To my pleasant surprise, and with my above disclaimer in mind, I would have to say this Butterfly "appears to be" much more calm and relaxed, judging from it's behaviour.
It appears to be quite content in there, cruising around quietly, eating frozen Mysis after only two days, playing with it's reflection, and sleeping at night in the tunnel with the Shrimp.
This time, I am not getting the feeling that this environment is doing the fish more harm than good. I want to keep this Butterfly in quarantine for at least two weeks (Butterfly reputation?) and was concerned that if I placed this type of fish into an environment that was causing it stress and/or discomfort, that it may actually become unhealthy while in quarantine even if it wasn't unhealthy to begin with.
Does any of this make any sense at all to those of you who know about fish, or is this just a case of amateur imagination gone wild?
<I do believe you're spot on with the "calming influence" of the purposeful cleaner, companion here>
Is there any reason why I should not do this?
I realize that the fish will not be alone if he develops a health problem while in the QT, but I couldn't help but think that the calming effect of the shrimp in with the Butterfly might lessen the likelihood of stress induced health problems, or an inability to recover from a problem under stressful conditions and, therefore, the (potential) benefits would outweigh any (potential) risks.
Your thoughts, if any and as always, are greatly appreciated.
Thank you for your time.
Mike

Nitrite Question, Copper murdered my nitrifying bacteria? (And QT) 6/7/07
Hello Crew.
<'Allo!>
I have a question about the effect of copper on nitrifying bacteria.
<Kills 'em.>
I have a 30 gallon marine QT/hospital tank that I cycled with two mollies.
<Poor mollies...>
I have since had to introduce my four fish---a tiny gold stripe maroon, a tiny blue hippo, a lawnmower blenny and a 3.5" yellow tang--into the hospital tank to allow my display tank to go fallow because my blue hippo got Ich (I know, I know . . .).
<Hope this is a big system we're talking about, 125g+ ???>
Of course, my ammonia and nitrites shot up - ammonia went from 0 to 2 ppm and nitrites went from 0 to 2.5 ppm. I'm treating the tank with copper (keeping it between .15 and .30 ppm, but boy are those tests hard to read!).
<Seachem?>
They've been in the tank 5 days.
The blue tang and maroon clown are happy as clams--you'd think they have known each other since birth. They seem totally unaffected by either the copper or ammonia/nitrite levels.
<I'm sure they are affected, whether or not it's apparent.>
The lawnmower blenny, who was perfectly healthy when I removed him from the display on Saturday, is now resting peacefully in pet heaven with my German shorthaired pointer.
The yellow tang is hanging in there--he hasn't eaten since entry into the tank and periodically leans over to one side, but he is responsive when I approach the tank, stick my hand in, etc., and he's alive every morning when the lights come on. His breathing is not labored, but I can tell he's not feeling great.
I have been doing 20% water changes daily and re-dosing to maintain proper copper levels.
<Hmm... maybe you should brush up on QT setups? http://www.wetwebmedia.com/QuarMarFishes.htm You need to be doing water changes that will keep the toxic byproducts of their respiration and feeding to a minimum. Usually 20% is not enough with four animals in a 30-gallon. >
Yesterday, I added Bio-Spira, which dropped my ammonia down to 0 overnight but my nitrites were still about 1.5-2.0 ppm this morning.
<Hmm, the addition of Bio-Spira is mostly moot at this point. As you are seeing, the copper has deleterious effects on the bacteria, and they won't properly establish in the presence of medication. This is a good reason to use the water from your main tank to dilute the toxins in the QT whenever testing indicates a need. Think of it as aggressive water-changes for your main system...>
My questions: What effect will the copper have on my nitrifying bacteria?
<See above.>
Do you recommend that I do multiple doses of Bio-Spira while I'm treating with copper?
<No doses would be fine.>
Do you recommend anything different with respect to the yellow tang to up his chances of survival?
<Just refine your approach to new species introduction in the future. I think you have taken a concerned and proactive approach to the current situation.>
My LFS will cure ich without chemicals (using an incredibly ingenious, patent-pending (no kidding) top secret method--I'd have to kill you if I told you how it works) for $5 per day.
<Per fish? What a racket! I should've thought of that one!>
I could send him there until I ran the copper treatment on the other two fish and then put him back in the QT, but it would certainly be cheaper to just buy another yellow tang (but what kind of father would I be??).
<Yes, we usually shy from relating importance of our livestock to their cash value...>
Thanks for your guidance.
<You are most welcome, but I bet you will do fine as you are. Do some google searching here on WWM and read as much as you can. In no time, you may be the one answering the Q's. >

Re: Copper murdered my nitrifying bacteria? (And QT) 6/7/07 – 6/8/07
Follow up for Graham:
<Howdy, Andrew.>
My tank is 110 gallons.
<Good.>
Your inquiry about Seachem copper test - - - yes, why do you ask? Is
that a bad test kit brand?
<Well, it a hard test to read results from. The slider, right? [Shudders]>
All of my test kits are Seachem, except my calcium test. I sure wish there was an easy to read test kit--do you have any recommendations?
< http://www.wetwebmedia.com/coppertestfaqs.htm >
I know that everyone speaks highly of Salifert, but I have to give up an arm to buy one of those kits.
<Hmm... get what you pay for, I'm afraid. I like the Lamotte kit Rick O. has with the colorimeter (sp?)... makes the testing a snap.>
As for QT, I know, I know--I was an idiot, thought I could beat the odds, will never, ever, ever do it again, will quarantine all new arrivals for at least 2 weeks, etc. Hindsight is always 20-20.
<Been there.>
I was in the hobby 20 years ago and just got back in it. Didn't realize how much it has changed until I read Bob's book and found this website, both of which have really opened my eyes.
<Been there, too. Was out of the hobby for ten years when I fell back in...>
I promise to keep the questions coming . . .
<Oh, goody!!!

I thought a Quarantine was a place to dig up rocks! Dip procedures as well    5/3/07
Dear WWM Crew:
<Darrel>
Somewhere in this mess are a few questions -- I hope it's easier to read than it was to write.
<Okay>
Ahem.  Once I manage to get a fish to my display tank, it lives in a 0/0/0 (Ammonia, Nitrite & Nitrate) world with 10% water changed every week, lots of varied food to eat and few worries (not sure what a fish WOULD worry about, but there are no sharks, eels, groupers to eat them and no taxes to pay).  There is one little hawkfish that nipped my clownfish but he will be dealt with -- maybe a stern talking to or possibly a notation on his permanent record that will follow him for the rest of his life.
But getting TO my main tank is a tougher road than I'd have expected.
At the beginning, the wise, knowledgeable, caring experts at BOTH my LFS advised a 4 day 'waiting period' before placing their fish in my main tank.
<At least this is some interval...>
Since they know best and have years of experience, I followed their recommendations to the letter.    As you all would expect, after most of  the fish in the main tank died of Ick, a REAL quarantine program was instituted starting with a bare 10 gallon tank/hood/heater and HOB Whisper filter.
<Mas mejor... Much better>
Never wanting to see or hear about Ick ever again, this tank was treated with Copper Power (chelated copper) as per manufacturer's instructions.  But good luck getting a Nitrogen Cycle started in a copper treated tank.
<Or sustain such...>
  Maybe some people can but I never could.
<Me neither>
  This meant 3-4 10% water changes every week, which means re-dosing the copper --
<Yes>
and with the test kits available to the hobby trade it's like playing Russian Roulette with an automatic pistol.   I've tried all the major brands and their test kits and in my actual surveys 8 out of 10 people can't read the difference between the three shades on their respective color charts that differentiate between  TOO LOW--JUST RIGHT--LETHAL.
<Agreed... but there are better, useful kits...>
I lost enough fish to copper toxicity that I've decided to swear off Copper until I can obtain research grade tools. (working on that one already!)
<See Hach, LaMotte... they have reasonable-cost assays...>
MEANWHILE ....
I’m committed to an eight minute Freshwater dip upon initial acquisition -- with my only reservation being that all the emphasis on SLOW ACCLIMATION is tossed out the window with this method, isn’t it?
<Mmm, no>
Also, no buts about it … 30 DAYS from the last sign of ANYTHING before they see my main tank.   The thirty days of boredom rule will also be absolute.
<Javul!>
Which leaves me with two choices:
1) A ‘normal’ water setup for that 30 days with nothing but observation (other than the dip)
2) Hyposalinity for 30 days in a proactive effort to stave off parasites.
If I’m thinking correctly (and no that doesn’t happen as often as I’d like) – unlike with copper or any medications,  either of these options would allow a filter with activated carbon, Bio-Chem-Zorb or Chemipure or Purigen or anything I need to keep the water pristine, wouldn’t they?
<Could>
A) Would you recommend a hyposalinity quarantine for us newbies or just regular saltwater?
<For most species of fishes, all invertebrates, algae... regular>
B) Is there a pretty accurate list of fishes that can’t tolerate 1.010 ?
<Have never encountered such>
C) While we’re at it, a list of fishes that can’t tolerate a FW dip or maybe a duration/time table for various fishes?
Regards as always,
Darrel
<Mmm, much more than this to it... A need to as smartly apply your observation, judgment re the apparent state of health of said incoming fishes... and to bear close watch on their progress during the (aerated) dip/bath procedure... to remove to the system with full spg if/when too much stress is obvious... if so.

When I did the freshwater dip, I adjusted the pH and warmed it to the same temp as the QT, I did, however, put all the fish in the same dip. I assume I should have started fresh with each fish.  I did have them bagged separately, so why not separate dips?  When I did a FW dip on the last fish yesterday, I saw lots of "dust" on the bottom.  I read somewhere this is a good way to see if you have marine velvet and if so, will offer the fish some relief.
<Can be indicative of “dislodged” disease organisms>
He stressed after only a couple minutes in the FW, so I put him back in QT.  I had 0.40 ammonia in the QT today, I was expecting it since I fried the biological filter with the copper tx (CopperSafe)  Copper level is at 0.25  I did a 40% water change and refilled it with my main tank water and added some AmQuel.  My main tank has an ammonia spike of 0.20, I think because I took out some carbon I had in a filter bag a few days ago (dumb thing to do in hindsight).
<This shouldn’t have induced such a large increase in ammonia – presuming it was at 0 with the carbon>
One of the hermits has been running around frantically and the others aren't as active as they were before, so that is why I checked the ammonia.  I found one hermit dead (with no shell) so I don't know if it was the ammonia or if we have a killer on our hands.
<The lack of a shell probably shows one of his compatriots fancied a new home>
Nitrites and nitrates are both 0.  I added AmQuel to the main tank and will be doing a 20% water change tomorrow and probably twice weekly thereafter to help re-stabilize the system.  I'll stick with the 20% water changes on the QT daily, since there is no biological filter, with fresh saltwater from my supply, not the main tank.
<I do not advocate the use of these products in main system water as I feel there are to many variables from tank-to-tank for the “Guidelines” to take into account. Larger more frequent water changes would be much more “natural”, far safer and more beneficial. Also, aged saltwater is critically important with water changes, especially in quarantine as the fish will be stressed and “harsh” water will not help. 24-72hrs aging process>
As for the fish, he seems more active today, still at the bottom and a brown colour, but definitely moves when I come near (which he wasn't doing yesterday).  As for the QT, the water was cloudy before I put the fish in.  I am starting to wonder if maybe there was something in the tank, I don't remember if I rinsed it or not before filling it. And the smell was there before I put the CopperSafe in.
<Had the tank had copper treatment used in it before as it can leach into the silicon seals and remain there?! Good to hear the chromis is picking up though, alertness is very important as you’ve recognized, hopefully it can go on from here>
I have been vacuuming out all the uneaten food in the tank. The fish I have now still isn't too keen on eating (hasn't taken anything since I got him on Sat), I am going to try some brine shrimp tomorrow, I just worry more about polluting the water with food he won't eat and going without food for a few days won't hurt.  If it is a bacterial thing, the CopperSafe should take care of it, right?
<The copper is responsible for assisting in the removal of the trophonts. However, when the free-swimming stage of the Amyloodinium – the dinospores – become active it does not seem to affect these. Therefore continued use is needed to remove all infection at the affected stage>
I really don't like adding tons of stuff to the tank nity wity. Let me know if you have any other thoughts, your help is appreciated.  I got to go mix some more saltwater for tomorrow.
<Good, keep going and keep up the water changes, you have a good routine going. Hopefully with continued treatment and perseverance, you, your fish and your new-found experience shall prevail>

Olly,
The last fish has died.  When I woke up yesterday morning to check on him, I noticed he had red blotches on one side that were a little raised.  About an hour later, he died.
<Sorry to hear this, take comfort that you tried your hardest>
I was going to add some Maroxy (smells like bleach) but knew that probably wouldn't help and since he seemed to be on his last fin.  I assume he died from septicemia. A picture is attached.  I am pretty floored about the whole ordeal, I am the kind of person that feels bad for stepping on an ant!
<Compassion is essential to remove the ideology of fish as ornaments, you are realising them as pets, a great step>
With the wealth of information available, it seems something like this shouldn't have to happen, but I know it still does.  I am having some other issues with my main tank so will be taking a little break again to educate myself (and yes everything has been disinfected already).  What would be the best tx for something like this in the future?
<Follow the earlier emails and read more, it is impossible to read too much. You may have just been unlucky with this particular batch, do you know their origin? – Cyanide?!>
There are so many antibiotics out there and misinformation.
<Antibiotics – in inverted commas>
Obviously, copper for external parasites, I got that protocol down pat now from reading so much.  As far as antibiotics,  I am leaning towards Maracyn first and Maracyn-Two for more difficult infections or fish that won't eat.  I am also stocking some antibiotic-laced food.  I will be doing acclimation with NMB/Stress Coat/Maracyn as stated in your acclimation FAQ.  Just some clarification on the acclimation bit.  I am going to take some water from the QT and add NMB/StressCoat/Maracyn/pH down to it and then slowly add it into the container holding the fish and shipping water? Okay, then how do I acclimate them to the QT then, specifically, the higher pH of the QT?
Will the pH be higher by the time the acclimation has taken place d/t the aeration?  And won't this cause pH shock? I know you're not supposed to change the pH by more than 0.1 per 24 hour period.  Also, would you advise prophylactic tx of the QT with copper?
<All are posted. The pH of the quarantine can be lowered then raised to “normal” levels after the addition of the fish through water changes for more sensitive species to avoid large pH shock. Continue reading and learning, Olly>

To quarantine or not to quarantine... that is my question   4/16/07
Aloha boys and girls. My name is Alex (and I'm an addict...?)
<Sounds like you're ready for our 13 step pet-fish program... the thirteenth is where you turn around and go back to number one!>
and I would just like to thank you all for giving your time to this wonderful resource.  I owe much of my success in this hobby (just passed the 3 year mark with a beautiful sps dominated tank) to all of you for answering the questions posed by others and posting them for us all to read.
<Ahh, tremendously pleasurable to realize>
I myself am a long time reader but this is my first time writing. My question is this. I've just ordered a Blue Tang (Paracanthurus hepatus) from Live Aquaria and was wondering if what I read was true? Like I said I'm an avid reader (daily) of your wonderful site and I remembered reading a while back an article regarding acclimation on this particular fish. In your article Paracanthurus hepatus, the Pacific Blue Tang of Many Names you say not to quarantine this fish.
<This is my standard assertion re this species, several others... But some of the rest of the Crew here are more "strict" concerning carte blanche acclimation of marine (et al.!) livestock>
Under the Introduction/Acclimation section of this article you state to just do a PH adjusted freshwater dip and than add the fish to the main display. Is this true?
<Yes... unless the specimen/s (including other species in the same shipment) show obvious behavioral and/or parasitic anomaly>
Is this still your opinion?
<Yes... with the above qualification>
I'm a true believer in using a QT having never lost a fish or had any issues and have a 30 gallon up and running for this purpose.
<Good. A good size>
I'm somewhat in agreement that the stress involved in moving the fish from one tank to another may out weigh the benefit of the quarantine but is it worth the risk of possibly introducing ich or some other pathogen to my well established tank?
   Thank you for your time (YOU GUYS ROCK),
            Alex Mattern
<Mmm, well... where/when in doubt, I default to the more conservative end of actions, considerations... Do quarantine the new Tang if you would like (along with FW dip/bath) enroute to the QT... For myself, having handled many specimens in commercial settings, much more likely/often the dip/bath alone is more efficacious. Bob Fenner>

Quarantining livestock enroute from one tank in a house to a new one?   - 4/7/07
Hello Crew, first off, I am now quite addicted to your site, and read
your FAQ's daily.
<Heeeee! I as well>
It is a great resource, and has helped me avoid some HUGE problems in the past.  I have a quick Quarantine question for you.
I currently have a 40 gallon aquarium up and running for approx. five years.  I've finally talked the wife into a 100 gallon, and it's now cycling.
<Great>
In the well established, overcrowded 40 gallon I have a 3" Kole Tang,
<Ooh, just finished an article re this species, Ctenochaetus strigosus, yesterday>
3" pink spot watchman goby, 2.5" algae Blenny, 1.5" false Percula, 1" 6-line Wrasse, two 2" Firefish, and a cleaner shrimp.
<Yikes... the move's coming in just about the nick of time>
  I also have a Xenia colony that is spreading like wildfire, a Kenyan tree that frags itself incessantly, a toadstool coral, some star polyps, a
sun coral, a few mushrooms, and a few Zoanthids.
<How much space for water is there in this tank anywho?>
  I've recently noticed some white spots on my tang, although I'm not sure if it's Ich or simply his natural coloration changes.
<Stress my friend...>
He often seems to change his colors a bit from dark to light.  Either way, I don't want to risk introducing anything into my new tank.  I have set up a 20 gallon QT, which I will be running all fish hypo salinic in for at least a month, with a one week gradual accession of salinity to match the main tank.
My question is, does it matter in which order I QT the fish/corals before putting them into the main tank?
<Mmm... might I ask why you're doing this procedure?>
I know that I will have to split the fish at least in half, with probably the tang, blenny and goby in one batch, and the Firefish, wrasse and clown in the other.  I also plan on adding some PVC to the QT so the Firefish have somewhere to hide.
<Good>
  The coral has all been in the 40 gallon for anywhere from 6 years to 3 months, so do I still need to QT them?
<No... I wouldn't>
  And one last thing, after I have all livestock transitioned over to the new tank, would 6 or 7 small Chromis be too much of a bio load for the 100 gallon?
<Should be fine... but this fish-load is "about it">
I have a 20 gallon sump w/refugium underneath if it makes a difference. Thank you all for all the help, Vince
<I would likely move all in one fell swoop... along with most of the old substrate, rock and water... including your livestock! Bob Fenner>

Quarantine 4/3/07
Dear Bob,
<Hello, Chris with you today.>
After two years, my eyesight is starting to fail from having read thousands of your frequently asked questions. <Me too.>  I am humbled by the shear volume of knowledge at hand, and thankful that you all continue to answer the same set of questions over and over with good humor. <We try.> Indeed, I have taken much of what I have read to heart.  Most notably, I own a quarantine tank, and use it religiously. <Excellent>  Nearly eight months ago, I added a coral to my show tank that spent 4 weeks in quarantine.  A new form of calcareous worm (one without a feather), was imported into the tank with the new coral, and has multiplied steadily over the months to the point where much of my rock appears to be
