How to QT a mandarin for ich? 7/6/08
Hi there guys! Hope all is well with you over there!
<Thus far>
I've read your FAQs already, and it's said that mandarin's have a slimy toxic
coat but can also harbor the ich parasite.
<Seems to>
How can I QT a mandarin with hyposalinity
<I wouldn't>
for 6 weeks to fully get rid of ich - as these guys don't readily eat pellets,
are quite hard to train.
Best regards!
Jason

Ick and wrasses/gobies
12/18/07
Hello!
<Jonathan>
I've been about a month now into the fallow period of my 90G reef tank. I slowly
increased the temperature to 85 degrees in that tank and everything handled it
very, very well. I've read that that's about tops you can go temperature wise to
at least speed up the life cycle of crypt a tad.
<Yes>
But anyway, my wrasses (now only 2 since my clown wrasse skyrocketed out of my
tank during a routine cleaning and didn't survive when he was put back in :( )
both have never had a spot on them and neither has my yellow watchman goby. I've
never been a huge fan of dipping my wrasses in the past, because they tend to
freak out way earlier and I (again, my own opinion) think that they don't
tolerate it near as much as other fish I've had in the past. But back to the
main point -- both them and the yellow watchman goby have never had a spot of
crypt on them that I could see with my own eyes. It was the more
crypt-susceptible fish that, unfortunately, succumbed.
They've been in quarantine/hospital for about 3 and a half weeks (and likely at
least another 3 weeks) and look absolutely fantastic. Temperature was slowly
increased to about 89/90 degrees for a few weeks and has now been reduced to 80
degrees -- in simple hopes to speed up what crypt was likely present in the q.t.
But I never saw any white spots at the bottom of the tank so I would have to
guess that the wrasses and goby are crypt free, considering I never saw a dead
white cyst or free swimmer laying at the bottom of the empty bottom. One would
likely be correct in thinking that, correct?
<Not necessarily. Easy to miss>
The reason I think it never happened is because I re-acclimated the fish to new
water in their q.t. tank and the fact that I've never seen a spot of crypt on
any of the 3.
I'll probably dip both wrasses and the goby on the way back INTO the display
after their time in q.t. even though it goes against my view with the wrasses
(mainly bad luck a few times with them but no other fish I've had has ever given
me a problem with freshwater dips outside of wrasses) just to give some added
assurance that the crypt has finally cycled out.

If only.. quarantine, Crypt 3/8/07
Greetings Bob and/or Crew Member.
<Hello Brandon here. Do keep in mind that there are more than just one crew
member.>
If I'd just done what I knew I was supposed to do (based largely upon
information freely available at WWM) everything would've been fine.
<Sad but heard so often.>
Instead, I was really eager to place my new mandarin into the 125 gal system
that I've designed around this particular fish's needs. In my eagerness, the
bad advice from my LFS that mandarins don't get ick due to their toxic slime
coat and therefore don't need to be quarantined sounded moderately
plausible. Plausible enough that although my QT was up, running, and ready as
it had been for every other swimming thing I've put into the tank, I bypassed
it, and dumped the happy healthy looking guy into the display tank.
<This mucus only keeps them from getting eaten.>
For any and all readers of the Daily FAQs....DON'T MAKE THIS MISTAKE.
<Quarantine is something we strongly advocate.>
My Powder Brown Tang is now well and truly infected with ick. Fortunately, he's
still eating and looks otherwise healthy, so I'm hoping I have a chance of
making this a not-too-painful reminder of proper quarantine habits. The
mandarin, for what its worth, looks very healthy read: plump, although I have at
one time or another observed a single white spot here and there.
<You will wind up removing all of the fish.>
My question is this...I'd like to avoid running copper full time in the QT, so
that it can double as a place to put corals etc when not occupied by an incoming
fish. I've made peace with needing to tear down my display in order to get all
of the fish removed so as to let the display run fallow, and am hoping that as I
remove each fish, I might get the results I'm hoping for by running a freshwater
dip treated with copper while en route to the QT for the fallow period.
<I would use Methylene Blue in the dip. Copper will have to be continually
monitored. Please read here,
http://www.wetwebmedia.com/ichart2mar.htm.>
Based upon my review of the ick FAQs, I'm fairly certain that you'll suggest
running the copper in the QT, checked twice daily via proper test kit, for 2-4
weeks with an additional 4 weeks in QT without copper. <Yep.> I'm just
thinking/hoping that the dip may provide the benefits of copper without the
prolonged exposure <Nope.> that may have implications for especially the tang's
long term health. Am also confounded by the prospect of providing proper
mandarin food in the presence of copper...pretty sure that can't be done, and
would result in turning a plump, if infected, mandarin into another deceased
mandarin story.
Perhaps the solution here would be to treat the mandarin as advised on WWM for 2
weeks, then if all is well, find a boarding home for him for the remainder of
the fallow period?
<Well this is what I was going to suggest, but since you already have, I guess
you know what to do. :^P>
Although would feel even worse about pawning the parasites off on a friend.
<Treat for two weeks, and then board him with an INFORMED, and willing friend.>
Looking for help in achieving the elusive balance here.
<I hope that this helps.>
Thanks in advance,
<You are welcome, Brandon.>

Ich and The Goby 8/30/06
Hello again.
Thanks for the help with bitten Big Mama (RIP). Now I have an ichy marine
question.
Though I quarantined my teeny pink skunk clown fish in my partner's ISO tank for
3 weeks, I neglected to (of course) quarantine the 3 green Chromis and 1
reticulated humbug damsel I put in when I first started the tank (i.e., the
Chromis and damsel are the original inhabitants). To date, the Chromis & damsel
remain ich free. The clowns, OTOH, are most definitely not. They are covered
in ich (some mornings it looks like I tossed them in my sugar bowl, though they
look much better within a couple of hours) and though fire shrimp is doing his
best to keep up with it (and my local LFS is out of cleaner shrimp), and we did
desperately try NSF (completely useless) as a last resort, the clowns remain
ichy. They are however eating, swimming, no clamped fins and no laboured
breathing, no cloudy eyes - they just look like sugary clownfish.
<Too likely to become debilitated... killed on next cycle...>
My tank is 30 gallons and has about 50lbs of live rock, several hermits and
snails, two corals, the fire shrimp and a pistol shrimp, who is best pals with
his friend the pink spotted Watchman Goby. Which leads me to my question(s): I
have set up a 10 gallon ISO tank treated with "Coppersafe" and the fish will be
making this their new home for the next 6 weeks after I dismantle all the live
rock tonight to catch them (*sigh*) and let the main tank go fallow. I know
Gobies are sensitive to copper and don't want to kill him in the ISO tank, but
am afraid if I leave him in the main tank the Ich will have someone to live on.
<Will>
Goby currently remains Ich-free and was in the LFS for 3 weeks with no problems
before I broke down and bought him and pistol shrimp.
The clowns came down with the Ich the day after I added Goby (whom I could not
quarantine because the QT tank I was using at the time has a purple tang in it
2/3rds of the way through its quarantine) (complicated, yes, sorry). Plus I had
read that Gobies were pretty disease resistant. Goby does not bother anyone in
the tank, so I don't think he is stressing out the clowns. My water has been
excellent and no fishy deaths.
1) Is Goby better off in the big tank or the ISO tank? Can he survive the
copper?
<I'd move... have to remove all fish/vectors... and treat on the low side of
physiological dosing... 0.15, 0.20 ppm free cupric ion>
2) If I leave him in the main tank, is he going to host the dreaded Ich cycle so
my fish can never return?
<Yes>
3) If I do separate him from his friend Pistol Shrimp for 6 weeks does that
mean the relationship is over, or will absence make the heart grow fonder?
<Will become re-acquainted on return>
4) How long before I can consider the Chromis ich-free and return them safely to
the LFS, as I don't really wish to keep them.
<A month or so. Bob Fenner>
Thanks so much.

- Ich, Quarantine, and a Mandarin Dragonette -
Hi, I just found out about this website, thank you for the hope you offer my
fish! I have a complicated question, and don't want to overload your
system, but I tried to include as much background as I thought might be
relevant. And probably forgot to include some too.
I have myself and my fish in a corner by simply reacting and not studying up. I
thought my fish would be covered with ich and die in 3 days if I didn't get some
meds in the tank right away. I went down to the LFS and was given a
choice of 3 medications and no idea what they would do. I started the
treatment that night with Kick-Ich. The next day I started searching
and found your site. On your advice a 20 gal tank for quarantine is set up and
running now. (not on your advice) I also bought a 15 w UV
sterilizer. When I installed the UV I noticed my skin burning from
the display tank water. (Kick-Ich?) After reading your
opinion on this I stopped after 2 treatments. Also the snails become
unconscious??? in the display lying fully exposed on the sand so I moved them to
the QT. <Would expect the snails to react negatively to the Kick-Ich. Would
just remove them period... certainly not to quarantine where you might need to
treat the tank with something that might just outright kill the snails.>
I have a 5 year old 60gal. tank, not sure but 50 or so pounds live rock, 3"
sand/gravel bed wet/dry filter and sump (have photos if you
want) 2-tube 40 watt light fixture
Salinity 1.020; ammonia 0; PH 8.3; Nitrates under 10 (the kit is only
in increments of 10) I have an AquaC skimmer but have not used it since the (Grrr)
Rio pump quit.
The tank has been pretty stable for a year or so. I have a Percula
Clown, Yellow Tang, 2 green Chromis Damsels, some snails and BL
hermits. A couple of weeks ago I added a coral beauty and a mandarin
dragonet (who has been eating well from day one though I am watching him
carefully) The coral beauty was not so lucky, she was stressed out
from the move and hid for 3 days. When I finally chased her out I
could see she was in trouble, one eye cloudy and a clamped fin complete with
white spot starting where the black spot was. In addition I could see
the white specks on her. The previous inhabitants had some spots for
a few days but not now, but both the mandarin and the coral beauty have spots
and ALL fish are twitching and chafing. The white patch on the angel
is turning black again and the eye is better, but the spots are there the same
from the day I first noticed them, more in the morning, less in the evening.
I hope the preceding was not too much, but now I need a course to
follow. I plan to freshwater dip the fish, mandarin last, and place
most in the QT. Mandarin goes to the new 10 gal I will set up for
him. I have Formalite 2 to treat the QT, but not the
mandarin? I will do a large water change, (aerating a.k.a.) on the
display. I think I need a separate QT for the mandarin and have read
your answers to this dilemma, or should I leave him in the main tank? <I
would quarantine the Mandarin.> I would like to go a month with no fish in
the display but I refuse to sacrifice this little guy to starvation. <That
may happen no matter what - your tank is too small to support one of these fish
long term, even if it were the only fish in the tank.> (working on a refugium
solution). Am I on the right track? <Sort of, but I wouldn't let
your whole world hinge around a fish that was a poor selection in the first
place. I'd go ahead and try isolating all these fish and continue to attempt to
keep all the fish eating, including the Mandarin. Go ahead with the
pH/temperature-adjusted freshwater dips for all and keep under observation.>
Thank you for your time. Kevin.
<Cheers, J -- >
Treating Ick On A Touchy Fish
Hi Bob and Crew,
<Scott F. checking in tonight>
I am writing to you because I have a Mandarin dragonette that seems to have
fallen victim to a case of Ick that has already claimed the life of a Kole tang
in my 72 Gallon Reef tank. I fear that the Ick is preventing "Manny"
from foraging for food and he is starting to really feel the effects of this
parasitic disease. I am not sure if I should treat him as I would another fish
of take exception to the fact that he is extremely delicate and only
feeds on a diet of copepods and amphipods. What steps would you take in order to
rid him of the Ick parasite? Any help or advice you could give me would be
greatly appreciated in this matter. I am thinking of treating him with
Methyl-Blue in a small quarantine tank. Is this the best course of action or
would this do more harm than good?
<Well, Methylene Blue is really better as an anti-bacterial, and would
probably have little effect on a parasitic disease such as ick. However, if
you're leery (and rightfully so!) about subjecting an otherwise touchy fish to
aggressive medications, then you might want to utilize hyposalinity in the
treatment tank. I am not a big fan of this technique, but I have utilized it
with delicate fishes with some degree of success. Do read up on this technique
on the WWM site>
I got him as a rescue out of a barren 10 gallon tank from a friend at my LFS. I
would do anything I can to save him, as he is a really beautiful fish. Any help
is appreciated - thanks. Jason
<Well, Jason- I think that you can save him, but it will take pretty quick
action on your part...Get that hospital tank up and running, and start treatment
ASAP...Good luck! Regards, Scott F>
Ich harbor
Hi Bob,
<Hey Nick>
I have had two Blue Hippo tangs die from either Velvet or Ich ( I am not sure of
the diagnosis) and there is only one other fish in the tank. He is a small
yellow with bluish spots Watchman Goby and he is healthy, eating and has no sign
of any problems during any of the deaths. My question is will either of these
parasites die off with him in there. I know they will without a host in a
month's time but I am wondering if my Goby will act as a miniature "Typhoid
Mary" by not getting either parasite but somehow help it continue it's life
cycle.
<Good question... for me there's too much of a risk that your goby is
supplying a low-virulence haven for the parasite/s... I would go the route of
removing it to another system, elevating temp., lowering spg. and letting the
system go w/o any fish hosts for at least a month... Please see here: http://www.wetwebmedia.com/parasittksfaqs.htm
Bob Fenner>
Thanks,
Nick
Fallow tank question
Hi, all...
<Scott F. with you this evening>
I had a bad outbreak of ich due to a variety of reasons several months back, and lost all fish in a reef tank. <yuck>
I corrected what I think were the problems, but left the tank fallow only for 2 weeks before repopulating with a couple of fish (I'm *trying* to learn patience in this life :)).
<It IS a virtue, they say!>
Too soon, so I had another outbreak that killed the fish again. Or so I thought.
It's now been 4 weeks fallow, and I'm waiting another week before introducing any new fish (which are currently quarantined). The tank seems healthy (the corals are growing and thriving, but they seem lonely :)). However, I noticed that the last bout did *not* kill all the fish - I have a tiny goby that I bought in combination with a pistol shrimp during the repopulation a month back. For the first time in weeks, he poked his head out while I was looking, and he seems fine. There is *no* way to get him out of the tank without completely ripping the tank apart, which is not something I'm willing to do at this point.
Is this a setback to the "fallow" program?
<Well, honestly-yes- sigh>
He's obviously resistant to ich - would he still be a "carrier"?
<Certainly a possibility>
What are my options?
< A really tough call here-prudence would dictate that you remove the goby, too-but...You may just want to wait a few more weeks to see
if the ich manifests itself on this fish. Maybe try some biological cleaners, such as shrimps; reintroduce your fish and hope
forth best. It's a risk either way-you just have to make the call that serves "the greater good">
( After close to 5 weeks, I'm looking forward to getting fish back into the tank.
Arthur
<You've done a great job being patient-keep up the good work>
Ich in Reef
Bob,
What is your opinion on fish with light cases of ich that are maintained in a reef tank. I have heard that in tanks with live rock the fish can cure itself. I have a
Midas blenny (you may have recalled my first letter with the Magnum) that will have no spots on him for a few days, and the next day he will have around 12. This has been going on for about a month. He eats like a pig and does not "scratch". What do you think I should do?
Thanks,
Avery
<<
Definitely try the biological cleaner route... to tip the balance in the host/fish's favor. Do you have any Lysmata shrimp? Room for a couple of Cleaner Gobies (Gobiosoma)... I'd add either/both of these.
Bob Fenner>
