Final Stocking Order (and a Who Dunnit Mystery)     1/2/08
Dear Crew,
<Sean>
Happy New Year and thanks for all the valuable guidance you've provided as I've been upgrading to my 220g. The move of my fish from my 120g went well, and they have been LOVING the new tank. My current stocking, including the fish I currently have in QT, is as follows:
* Red Sea Golden B/F Pair
* Saddleback B/F
* Pearlscale B/F
* Lyretail Anthias Male
* Bartlett's Anthias Pair (was a trio, but one jumped ship -- new tank is fully covered)
* False Percula Clown Pair
* Mystery Wrasse (awesome fish!)
* Orangetail Blue Damsel
* Blue Green Chromis
<The Anthias and Chromis need more conspecifics to be happy>
The next (and last) fish to join the mix are the following angels and tangs:
* Rock Beauty Angel
* Potters Angel
* Flame Angel
* Purple Tang
* Whitefaced Tang (a. japonicas) OR Achilles Tang
* Kole Tang OR Tomini Tang
<Mmm, the two angels and the Achilles are not easily kept>
I have two 20g QT tanks and will also use my old 120g as an additional QT until the 220g is fully stocked. With these three QTs, I have a lot of options for quarantining order. I know I should add the most aggressive and most territorial fish last and that I should add only one species at a time, but with 3 tangs and 3 angels, I'm not sure what the best way to proceed would be, since they all fall in the aggressive/territorial category. I could add them all at the same time by spreading them out across the 3 QTs, but would 6 fish at the same time be too much of a jolt to the bio load of my 220g? If not, which combination of fish would you recommend in the various QTs? If it would be too much of a jolt to add all 6 to the display at one time, in what order should I introduce them?
To recap prior postings... To handle the large bio load, I have 300lb of LR, an AquaC EV240 skimmer with Mag 18 pump, a 65g sump and a 35g fuge (and will probably be adding another). Cleanup crew includes 1 fire shrimp, 3 skunk cleaner shrimp (though I'm thinking of adding a few more later), 4 small emerald crabs,
<Do keep an eye on these... as Mithraculus get bigger, they become more opportunistic and broader in their feeding habits>
11 Nassarius snails, 1 fighting conch, 5 serpent stars, Nerite snails and an assortment of critters I got from IPSF.com (sand bed clams, micro hermits, various worms, mini-stars, gastropod snails). Tank is set up as an island display with swim lanes on all fours sides of the LR.
One other question for you: Until today, I had 2 fire shrimp, but I found one this morning that literally had its tail chopped or ripped off. It was the largest (though not fully grown) and least shy shrimp in the tank, so I'm assuming that the other shrimp didn't do it, and the emerald crabs are likely too small (1 inch or less). Other than the wrasse or possibly the serpent stars, I can't think of anything else that would have done this.
<Might be a Mantis that hitchhiked in with your live rock...>
The wrasse sleeps at the opposite end of the tank, and most of the meat of the shrimp's body was still intact,
<Oh! Maybe some other cause... a Stomatopod, other predator would have dismembered...>
so it doesn't sound like the wrasse did it, unless he was just trolling for sport in the middle of the night. I had the wrasse, 2 of the emerald crabs, 2 of the serpent stars and 2 of the skunk cleaner shrimp long before the move to the new tank, and I've had no previous issues. The rest of the crabs, shrimps and stars were added a couple of weeks ago after everything stabilized following the move to the new tank. Any idea who Dunnit?
<Mmm, of what you list, no... maybe no one, as stated>
I'm worried that I've got some masked killer lurking in the new rocks that were added during the move to the new tank...
I've been testing the water parameters regularly since the move, and everything has been fine (pH 8.4, spg 1.024, temp 80, ammonia 0, nitrite 0, nitrates 2.5).
As always, thank you so much for all the help. Even my wife, who (probably correctly) thought I went off the deep end with such a large tank, thinks the new setup is coming along beautifully.

<Thank you for sharing. Bob Fenner>

Re: Final Stocking Order (and a Who Dunnit Mystery)  1/3/09
Thanks! Do you have any thoughts on my original questions regarding the stocking order for the Tangs and Angels? Here were those questions:
Would the 6 angels and tangs at the same time be too much of a jolt to the bio load of my 220g?
<Mmm, I don' think it will prove problematical... due to the size/volume of this system and the hundreds of pounds of LR... and there is much to be gained by simultaneously adding these fishes here.>
If not, which combination of these fish would
you recommend in the 3 QTs? If it would be too much of a jolt to add all 6 to the display at one time, in what order should I introduce them?
<I'd place all at once... or all the Angels at once, with the Tangs following weeks later>
Also, a follow-up on your comments re the Anthias and Chromis...
Although I have heard that the Chromis do better in groups, I've also heard that there's a good chance of one killing the rest and leaving you with just one anyway.
<Mmm...>
Would you recommend adding more now, given that this one is already established?
<In a sufficiently big system... not much dominance issue...>
He seems happy enough, seemingly schooling with the Anthias or Clowns some of the time... For the Bartlett's Anthias, could I add more at this time?
<Yes>
I always thought that they needed to come as a group (as they were before the suicide) and that you couldn't add more later. They seem to be happy as a pair.
For the Lyretail male, I thought from your website that these were OK as individuals. He's actually still in the LFS QT with several females, and I was going to move him to my QT this weekend. I don't think I have room for the whole group, so I was just going to take the male so that one of the females could step up and wear the pants in the group for someone else who has room. Would you not recommend this?
Thanks again!
Sean
<The male won't be as colorful, active... happy as it would be if kept in a haremic circumstance. Bob Fenner>
Thanks again for all the helpful guidance!
<Welcome Sean! BobF>

Re: Final Stocking Order  1/5/09
As I think about how to implement your recommendations, I have a few follow-up questions... I'm thinking about downsizing my B/F, angel, tang and anthias selections to make room for more anthias and chromis fishes, as you suggest. Here's what I'm thinking:
B/Fs: 1 Latticed, 1 Pakistan, 1 Pearlscale and 1 Bluestriped Dwarf angels: 1 Bicolor, 1 Flame and 1 Coral Beauty. Will 3 dwarfs likely get along in a 220g if added at the same time?
<Likely so>
Tangs: 1 Kole and 1 Tomini. The Kole article on WWM suggests that 2 Kole Tangs would likely get along in this size tank, but I'd prefer a little diversity. Would the Kole and Tomini likely get along?
<Ditto>
Anthias: 4 Bartlett's (the male and female I have now, plus 2 more female) and 3 flame anthias. Should I add the 2 Bartlett's and 3 flame at the same time, or should I complete the Bartlett's group before introducing the Flame group?
<Six of one...>
Generally, I also realize that the B/Fs, angels and tangs are all similarly sized/shaped. Should I be concerned, or is this enough diversity for this sized tank?
<... Is, IMO>
One last unrelated question... IPSF.com lists micro hermits as no threat to the snails, but I'm having my suspicions after seeing one trying to prior open one of my sandbed clams.
<I'd believe my own first-hand experiences... "We're bringing freedom to Iraq"... No, we invaded a sovereign nation and have murdered hundreds of thousands of their citizens>
Seems to me they may still decide that they would prefer one of my snail's shells more than its own
<Mmm, with all Hermits, one needs to be providing a mix of shells for "upgrading"... otherwise they will improvise>
or may just want to take one apart for the fun of it. Are micro hermits really safer, or should I be almost as concerned about them as for the bigger hermits?
<Less concerned, but still so>
With two Bristletooth tangs and the rest of my clean-up crew, I'm thinking about evicting the micro-hermits.
<I would as well>
Thanks again!
<Welcome! BobF>

Re: Final Stocking Order  1/5/09
You are too funny... I think I'm finally set on my final selections and stocking order. Thank you for all the valuable insight to help me nail all this down. Cheers!

<Happy to conspire with you Sean... Anticipation is a huge part of fun in this hobby... even more so when shared with others who are intelligent, sensitive and open to possibilities. BobF>
I agree completely!

Stocklist for 120 Gallon Marine Tank ~ 12/27/08
Hi Guys,
<<Dean>>
Late 2009-early 2010, I am going to be starting a 120 gallon Marine tank.
<<Neat!>>
I am unsure if I will have a reef or FOWLR but I will make my decision.
<<Ok>>
The tank is going to be 4'x24"x24",
<<Indeed, a standard 120… And a great choice for a medium sized tank, with the added inches of the front-to-back dimension over other standard tanks of similar size>>
with separate sump filter and protein skimmer. My fish Wish List is as follows-
*Majestic Angelfish
<<Will ultimately require more space>>
*Bicolor Angelfish
*Foxface Lo
*Yellow Tang
*Sailfin Tang
<<Will also require more space>>
*T. Percula clownfish pair
Would I be able to drop the 2 Tangs (Yellow and Sailfin) and add a Lipstick (Naso) Tang or would the tank be too small for one of these?
<<If you are considering the long-term health of these fish, then I think this is simply replacing one poor choice (the Sailfin) with another>>
If I was to keep the 2 tangs and not replace them with a Naso would I be able to add a Flame Angel or would this cause a fight between the Majestic or Bicolor.
<<The Majestic likely wouldn�t be much of a problem re, but an *established* Bicolor would certainly have issues with the Flame. Though if two dwarf angels are introduced together they may well coexist in this size tank. There are many *suitable* fishes available for this tank… And you have the time to do the research…>>
Thanks for the help.

<<Happy to share. EricR>>

Stocklist for 120 Gallon Marine Tank… Pt2 ~ 12/27/08
Hi WWM,
<<Howdy Dean>>
I have recently sent you an email about stocking my Marine Tank around this year.
<<Ah yes… I think I just replied to it>>
I was talking about something like a Majestic Angelfish and a Naso Tang.
<<Yes>>
After further research I realized that a 120 was 2 small for these both as individuals,
<<Ah!>>
and at the end of the day it's all about providing the Marine life we keep with the best environment possible.
<<Indeed… Is our responsibility as petfish keepers>>
I thought that keeping one of these fishes in that aquarium would not be meeting their needs and I wouldn't like to give a Fish a not-so-good life that it shouldn't have had.
Anyway, I currently have a nano reef and am going to upgrade. I have decided to have a FOWLR and my fish list is as follows. Could you please point out any compatibility and/or tank size specifications?
<<Happy to proffer my opinion>>
I have done research on these fishes and according to my research they are all okay but I always feel confident getting your opinion as I find your advice very knowledgeable and helpful.
1 Foxface Lo
1 Sailfin Tang
1 Bicolor Angel
1 Flame Angel
2 T. Percula clowns
1 Double Saddle Butterflyfish
Thanks heaps once again.
Dean'
<<I still consider the Sailfin Tang a marginal choice for the 120 (I've seen pairs of these fish off the Big Island of Hawai'i that were *bigger* than dinner plates). I think a smaller species would be a better choice for the long-term. Otherwise, this looks like a fine selection for this tank. Do closely watch the Centropyge angels when introduced, but I think there is a good chance they will coexist in this tank. Regards, EricR>>

Re: Stocklist for 120 Gallon Marine Tank… Pt2 ~ 12/28/08
Thanks once again for your help.
<<I hope it has been of use>>
I would have dropped the Sailfin Tang from my list but I had sent the second email, before you replied to the first.
<<Ah, okay… Though it would seem a small (2-3 inch) specimen would do fine in this tank; and it might for a time, one should also consider the possible sociological/psychological effects on such a fish as this from growing up in a too small environment.
Are there any Tangs that I can keep in this tank without compatibility issues?
<<Certainly… I think it would be possible to keep one of the smaller Zebrasoma species with a like sized Ctenochaetus or Acanthurus species. For instance, a Yellow Tang (Z. flavescens) and a Kole Tang (C. strigosus), or a Kole Tang and a White Cheek Tang (A. japonicus)>>
If not, can Foxface Lo be kept as pairs?
<<I have heard of rare instances where multiples of differing species have been kept together. But unless you can obtain a natural *pair* I wouldn�t suggest this here>>
Could you please mention some other choices of fish?
<<I think your earlier listing provides an interesting mix of color and size. My only other suggestion might be to add a few small fishes from a schooling species like Cardinal fishes. Perhaps a grouping of five Longspine Cardinals, or Pajama Cardinals>>
I am mainly wondering if I could have a yellow tang or purple tang?
<<Sure… As previously outlined…>>
Would one of these be compatible with the other tankmates?
<<It would… The issue (in my opinion) is not that you have a Tang on your wish list, but rather the species chosen. And there are those no doubt that would say my advice concerning the Sailfin is too conservative. The onus is upon you to derive information from *multiple* sources and then use your own good judgment to come to a decision>>
Thanks,
Dean'
<<Happy to assist. EricR>>

R2: Stocklist for 120 Gallon Marine Tank… Pt2 ~ 12/30/08
Hey guys,
Would just a yellow tang be fine with the other tankmates?
Thanks
<<Hmm, isn't that what I said before [grin]? Sure... A Yellow Tang will be fine with your other choices. EricR>>

240 Gallon FOWLR Compatibility
Big Tank/Big Plans/Big Tradeoffs (Stocking a 240 FOWLR)  12/4/08
Hey Ya'll!
<Hiya! Scott F. in today!>
I am in the early stages of planning a Fish-Only/Live-Rock tank probably shooting for 240 gallons. I normally wouldn't want to waste your time, but some of the stocking possibilities will play a big role in the amount of money I want to put into the project.
<I'll bet!>
Besides that, I have seen a lot of information about compatibility and requirements of space for the fish I am considering, but I have had a hard time finding anything that gives me a comprehensive answer about the big picture. One thing about the aquarium shape/size itself: I have this crazy notion that somehow a deeper, more square tank gives fish a greater feeling of freedom when swimming. For example, is there any reason to think a 48x48x24 240 gallon as opposed to a 96x24x24 240 gallon would allow creatures like a Koran Angel, Lunare Wrasse or Zebra Moray Eel to feel like they have more open space in which to roam? Or, am I just crazy? It seems like the longer, narrower tank would be more cost effective so that's where I would probably lean if it doesn't change things much.
<Good thought. I'm all about wide, low aquariums, but in the case of fishes that "range" over large territories in the wild, I would prefer a longer aquarium.>
My biggest question is about the compatibility of fish but even more so about a sequence of introduction. The fish I am most desiring to house are the following ordered from most wanted to least:
Koran Angelfish, Dragon Wrasse, Harlequin Tuskfish, Zebra Moray Eel, Lunare Wrasse, Dogface Puffer, Naso Tang, Niger Trigger, Antennata Lionfish. I am guessing that the Lunare Wrasse is the most likely to be incompatible with something else on the list even if added last. I also feel like the Lionfish and the Trigger could be particularly aggressive towards some of the others especially if they are still small, right?
<Oh, yes!>
A loose plan I had would be to add the Koran and Dragon as juveniles because I would love to be able to watch them change. I figured the Harlequin Tuskfish, Naso, and Dogface would probably be next. Would they be dangerous to add while the first two are still juvi's? After some time I thought adding the Trigger and the Lionfish. I definitely figured if it's compatible at all, the Lunare would have to be last and I really wasn't sure about the best time to add the Zebra Moray Eel. So the big questions are, of course, are there any glaring compatibility issues in the list? Would you make any specific alterations to my basic sequence of introduction? Is this too much fish(&eel) for 240 gallons?
<To be honest, I'd avoid keeping Naso Tangs in aquariums. They just get so large and require large amounts of physical space to live anything close to a natural life span. In my opinion, too many of these magnificent Tangs die needlessly in aquariums that are too small to sustain them. Other thoughts: I would pass on keeping both a Trigger and a Lionfish together in the same aquarium. For that matter, do consider the Puffer as a potential problem for your Lionfish. I would also consider choosing either the Lunare Wrasse or the Harlequin Tusk Fish-but not both. They could get pretty aggressive towards each other.. I would get the Moray Eel in the aquarium as soon as possible and get it eating before any of the other fishes are introduced. I would probably avoid small juveniles of the other fishes, so that they don't become snacks for the Moray. Stocking involves lots of trade offs, huh? Also, take into account the amount of metabolic  wastes that the fishes you are considering will generate!>
I had considered a glith upgrade to 300 (96x24x30) but don't know even how much difference that would make at this level.
<You'd be surprised what a difference it can make. If you're gonna do a big aquarium, the extra 60 gallons is well worth the additional expense, IMO.>
Again, I don't think there's anybody out there who I've seen give better advice so I would greatly appreciate your thoughts!
Scott
<You're too kind. Thanks for the compliment! Best of luck to you. Regards,
Scott F.>

Re: Identification help? And a whole lot more!
Little Fish For Little Aquariums!  12/4/08
Scott, in no way did I think you were being insensitive! I actually got a really great laugh out of your responses! I was afraid I was looking at too many/big fish for each of the new tanks.
<I'm glad that you saw the humor! Really makes sense to review the stocking requirements of these fishes.>
Ok, if I may (again), ask some probably redundant/stupid questions....
#1 Can a lionfish & a puffer exist together in a 55 if that is all the livestock that is in there? Assuming here that I go with the Fu Manchu lionfish and a Blackspotted puffer or spiny puffer. Of all the more aggressive fish, these are the two that I really, really want.
<Umm, I really would not mix a Puffer with a Lionfish. The Lion is apt to become a chew toy for the Puffer! Besides the active Puffer may intimidate the rather shy, reclusive Lionfish.>
#2 I want as many fish as possible in the peaceful 30 gallon. What would you recommend getting to make the tank look really "full" without it exceeding it's limitations for it's size?
<Seriously? I'd opt for really tiny fishes, like small gobies- Stonogobiops, Coryphopterus, Eviota, Discordipinna, etc.>
#3 The Ricordea Yuma--I found one online that looks similar and is very, very expensive per polyp. How would I determine what color/kind mine is?
<You may have to go online and look at some user groups for Ricordea enthusiasts.>
#4 Lighting--you mentioned that you thought T-5's would work well for most corals. Is there a certain type (SPS or LPS or leather) that they would work with? Is there a certain type of coral that absolutely needs the intensity of the metal halides? With a T-5 setup, could I get one small hang-on or clip-on metal halide to focus on a specific set of corals if they needed the higher intensity?
<Hmm...really a general question that is hard to answer. I'd get a lighting system that provides flexibility- T5 or Halides work well for a wide variety of demanding corals.>
Okay that last one was really like four questions all in one! Sorry about that!
<No problem!>
I would like to thank you for the link to the information on the Banggai Cardinalfish. I think for the time being--until someone figures out for sure if they are endangered--that I will just stay away from those fish! They are beautiful though!
<Good call! Until tank-raised specimens are more commonplace, I'd pass.>
Well I suppose this is it for now! I look forward to hearing from you guys! And, many thanks again for all your help!
Angela
<Glad to be here for you! Good luck! Regards, Scott F.>

Seeking second opinion on FOWLR stocking. 11/23/08
Stocking Up (Fish selection)
Hello Crew,
I sent this in a few days ago, but I think it got lost in space.
<Scott F. here...Checked in space but found it in the inbox right here!>
I'm seeking a second opinion on stocking a 150 Gal (568 liter) FOWLR.
<Ok...>
Here are my specifics:
150 gallon tank (568 liter) - 48" x 24" x 30" (122cm x 60cm x 76cm)
200 lbs (91kg) live sand + 40 lbs (18kg) crushed coral
170 lbs (77kg) live rock
For filtration\water movement, I have a Rena XP4, three powerheads, a Coralife 220 super skimmer. The turnover rate is approximately 10x the tank volume. I do not have a sump at the moment, however, will be added during the holidays.
Water parameters are: Ammonia: 0, Nitrite: 0, Nitrate: 0, Phosphate:
0\undetectable, dKH: 11, pH: 8.3, SG: 1.025.
My current inhabitants are
1 x juvenile Sailfin Tang (Zebrasoma veliferum)
<A neat fish, but it can/will reach an ENORMOUS size (up to 15"!). You should re-think this one for the long-term.>
1 x Ocellaris Clownfish (Amphiprion ocellaris)
1 x Royal Gramma (Gramma loreto)
1 x Blackcap Gramma (Gramma melacara)
<Unusual to have both of these species in the same system..>
1 x Cherub Angelfish (Centropyge argi)
1 x Yellow head Jawfish (Opistognathus aurifrons)
2 x Blue-Green Chromis (Chromis viridis)
2 x Redlegged Hermit Crabs
4 x Bluelegged hermit Crabs
1 x Peppermint Shrimp
Multiple Turbo Snails (Started with six, they are breeding).
<A nice stocking list. You seem to have a well-thought-out plan, although I do encourage you to fins a larger long-term home for the Sailfin Tang>
I would like to add 2 - 3 Firefish, either Nemateleotris decora or Nemateleotris magnifica and 2 - 3 Banggai Cardinalfish (Pterapogon kauderni).
<I think a group of the N. decora would be interesting, but the odds for success are really dependent upon the individual specimens' personalities.
These fish are surprisingly tough to keep in groups in captivity, with territorial disputes often slowly diminishing the population. Better to obtain individuals or mated pairs, if possible. Aggregations of these fishes almost always seem to end up with only one fish left, in my experience.>
My thought is, I am close to full capacity, but am seeking a second opinion. Would it be smart\safe to add either the Firefish or the cardinals, or on the outside chance, both?
<Hmmm. It's my opinion that both of these species are a bit too passive to add last to an established community without the better than average chance of bloodshed or death. I'm thinking that a more "solid" fish, such as a small-medium Halichoeres species of wrasse, should fit the bill nicely.
There are many to choose from, so do do some research here on the WWM site under the genius Halichoeres. There are many hardy, colorful fishes in this genus!>
Many thanks,
Mike
<My pleasure, Mike. Do keep in touch.
Regards, Scott F.>

FOWLR Predator confusion 10/24/08
Thank you in advance for your information. I have been reading and getting some conflicting or at least confusing information on your site in one particular area. I am converting one of my reef tanks over to a predator tank. Not sure of the exact mix, but something along the lines of triggers, wrasses, maybe smaller puffers or dwarf lionfish.
<Mmm, not Lions with these others... too likely to get picked on and/or starved>
Anyway, I've always been use to having a large clean up crew. Obviously with this mix, they will just get eaten.
<Yes>
There have been many questions on your site about predator tanks and pieces of meat landing on the bottom etc, and some of the responses have been that's what your clean up crew is for????
<? Not from me... am not a fan of such reliance. Please cite specific instances, their location>
After they had just named some of the most aggressive fish out there that was in their tank. So what clean up crew are they talking about that doesn't get eaten by say a clown trigger of dogface puffer?
<None>
If you can't have the typical cleanup crew, what do you use to keep your live rock and sand bed clean?
<You, your gear, careful maintenance...>
Thank you,
Brian
<Welcome. Bob Fenner>

Is It Okay To Add The Male bimaculatus Anthias First? – 10/20/08
After over a year of searching for a trio (I've been unsuccessful in finding a group), I've given up and decided to pick up a 4.5" male Twinspot Anthias (Pseudanthias bimaculatus) in hopes of picking up two to three females sometime in the future. The male is currently in a 30 gallon quarantine and doing well, eating mysis and brine shrimp.
<<Very good>>
I've read conflicting reports that the females should be added first or at the same time as the male.
<<This is the consensus for the “best” chance of a successful grouping, yes>>
I had also read that there was a risk that by adding the females first, that the dominant female would eventually change to a male.
<<More than just a “risk” if left too long…best to add the male within a week of introducing the females, in my opinion>>
Lastly, I had read that it was possible that the male would likely bully females added after the male had been added.
<<This too is true>>
Will I be ok with adding two-three females with the male?
<<Possibly>>
Or is this asking for trouble?
<<The more females added at one time the more any aggression will be spread around…be aware that the females too will establish a dominance hierarchy among themselves. Three is a good number…five would be better (assuming the system can handle them)>>
The main tank is currently a 100 gallon set up over a year and a half old, FOWLR. The tank is currently inhabited by a pair of 1.5" Ocellaris Clowns, a 4" Raccoon Butterfly, a 4.5" Achilles Tang,
<<Mmm…a delicate species that needs a bigger tank than this>>
a 3.5" Queen Angel,
<<Also “too much fish” for this size tank>>
a 3" Mystery Wrasse, a 3" Algae Blenny, and a 3" Eibli Angel. I know, too many fish for a tank this size.
<<Not “too many” for the tank so much as just inappropriate species selection re>>
I have a 240 gallon tank currently being set up, which will be the FOWLR for the Queen Angel, Raccoon Butterfly, Eibli Angel, and probably the Achilles Tang with eventually more fish.
<<The Queen Angel can reach 20” in the wild…and the Achilles needs lots of swimming room (and lots of water flow). With an eye toward the future, I would be reluctant to add anything but a few very small fishes here>>
The 100 will be converted over to a reef with the clowns, mystery wrasse, algae blenny, and trio of bimaculatus Anthias.
<<Do be aware the Clowns may pose a problem re the Anthias…I have seen Damsels chase small Anthiines to the point they jump from the tank in an effort to escape>>
Which, by the way, would it be ok to add one of the fairy wrasses to the 100 with the mystery wrasse? Or will they fight?
<<A similar or smaller sized specimen will likely be attacked>>
I enjoy reading your site and many thanks in advance! –Wes
<<We are all happy to share. Regards, EricR>>

Tankmate for Snowflake Eels and Friends, Tulip/Conch comp.,  – 10/16/08
I am in a school with three large marine tanks - one 55 gallon predator (will be expanding to meet the needs of these guys as they grow), one 75 gallon reef tank, and one 500 gallon touch tank. The predator tank has two snowflake eels (10 - 12") one volatin <Volitans?> lionfish (5") one dogfaced puffer (4") and two wrasse (one clown and one lunar).
<Better not confuse the predator with the touch tank, hehe. Oh, and medium sized wrasses have been eaten by larger Echidna eels. You will need a big upgrade in the not-so-far-away future.>
The touch tank has a beautiful Tulip Snail who has worn out his welcome. He is unkindly ridding my tank of all the other cleaners!
<Yes very, very predatory. Does best in a one-specimen tank.>
I have considered moving the Tulip to the "predator" tank but want to be sure he will not be bullied/injured by any of these current residents or be a threat to them.
<The latter. Wrasses and puffers sleep at night (partly), are still small and might become prey, even the eels are a little small. In addition, the puffer would become a threat to the snail, molluscs are their favourite prey.>
I could use a cleanup crew (even of one) in this tank. The tulip is quite large 7-8". If he is not suitable for this tank, could you make other suggestions for cleaners for this tank which won't be consumed by the predators. What about chocolate chip starfish?
<Would have been among my suggestions if you provide a good water quality. Can work in your predator tank, just keep the puffer away from the star for a few hours, he might try to sample it due to its “new” smell.>
Any other ideas?
<Very well armoured hermits.>
I also would love to try a coral here or there, but "Puff" (dogface) liked the looks of the rock anemone I recently tried briefly way too much!
<You can try a mushroom (Corallimorph), they taste nasty and are disliked my many puffers (not all, though). Another option might be a photosynthetic gorgonian or a leather coral, if you have reasonable lighting. However, it cannot be predicted what the puffer will eat and what he won’t eat, they really are individuals with regard too some of their foods.>
Thanks for your help.
<Welcome. Marco.>

Stocking and moving Plan for 220 Gallon FOWLR Tank 10/15/08
Hello Crew,
<Sean>
I'm upgrading from a 120g to a 220g FOWLR (72L*24W*30H) that will be set up as an island display with visibility from all 4 sides. The overflows will be in the corners, live rock will be in the middle (with plenty of see-through/swim-through areas) and the area between the rocks and the glass on all 4 sides will be left as open swim lanes. After much research, I've finally narrowed down my "wish list" (shown with adult fish size):
* Rock Beauty Angel (8")
<Mmm, a rare male... start much smaller... and this Holacanthus sp. is not easily kept... do read my acct. on WWM re>
* Flame Angel (4")
* Red Sea Golden Butterfly (9")
<Better in pairs/twos... I'd skip one of the other B/F's and get two>
* Saddleback Butterfly (9")
* Blue Striped Butterfly (5")
<A neat species... C. fremblii>
* Purple Tang (10")
* White-Faced Tang - a. japonicus not a. nigricans (8")
* 2 False Percula Clowns (already paired) (3.5")
* 3 Bartlett's Anthias (4")
* Orangetail Blue Damsel (3")
* Mystery Wrasse (5")
* Six-line Wrasse (3")
(About 83" total.)
I realize that the Rock Beauty requires plenty of sponge in its diet, and I've seen plenty of suggestions for food sources on your website, so I really want to give it a try, as this is easily my favorite fish. So, on to my questions...
* Bio Load - What size sump and what size refugium would you recommend for this to be a "safe" bio load with a 220g tank?
<Mmm, the biggest/largest you can fit in, really>
I am not limited to space inside the stand, as the sump and refugium will be located in the basement below the tank.
<Look into Rubbermaid's troughs...>
* Big Fish - The above includes 5 fish that are 8-10" in length. Is this too many "big" fish for this size tank?
<Mmm, no... given the shape, volume of the system... I don't think these animals will really approach their maximum sizes stated... Maybe half to two-thirds over years time>
* Aggression - The above includes a total of 7 angels, tangs and Butterflyfishes, which are reasonably similar in shape and diet. I only have 2-3 of each species, and with the exception of the Butterflyfishes, only one of each genus. I'm hoping that the genus mixture, coupled with the large tank size (with double the swim lanes resulting from the island set-up) will minimize the chance of aggression, or is this an accident waiting to happen?
<Mmm, no... I give you very good odds that you'll be fine here>
If so, would the situation be helped much if I "downgraded" the Golden Butterflyfish to a Lemonpeel Angel and/or "downgraded" the White-faced Tang to a Tomini Tang so that I have fewer of the "big" fish?
<Not really an issue>
* Wrasse - I've read that sixlines can be aggressive toward small, peaceful wrasse. Should I be concerned about the Sixline harassing the mystery wrasse in a tank this size?
<Mmm, no... s/b plenty of room for them to avoid each other>
If so, I might get a more peaceful radiant wrasse instead of the Sixline. Also, I've read some sources which indicate that all three of these could go after small ornamental shrimp,
<Can, do>
while other sources indicate that they are completely reef safe and won't harm invertebrates.
<Mmm, not so>
What's your impression? Would peppermints, skunk cleaners and fire shrimp be OK with all three?
<If all are well fed... better than even chances of getting along>
* Algae control - Without coral, I'll be able to go with minimal lighting, and I'll keep the temps around 76", but the tank will be exposed to quite a bit of direct sunlight. As this is a big, deep tank, I want to avoid having to go scuba diving to keep algae under control, so the stocking plan includes a lot of algae eaters. (I'll supplement with seaweed and algae in the feedings in case algae levels aren't quite high enough.) I've read that the Kole tang is the best for hair and bubble algae, but I just don't find it as appealing as the other fish in my wish list. Does the purple tang go after bubble algae?
<Mmm, no, not as much by far>
Does the white-faced tang or the Tomini tang go after it?
<The genus Ctenochaetus are best here, and with micro-algal species that are palatable>
I believe they all go after hair algae, right?
<Yes>
I know that emerald crabs eat bubble algae, but I also read many of your FAQs which indicate that they come with their own set of potential problems... Also, what critter(s) would you recommend for keeping the sand free of algae?
<A sand stirring goby or two perhaps (genus Valenciennea), and/or a goatfish sp.>
I have Nassarius snails and a sand sifting star in my 120g, but I still get a bit more algae on the sand than I would like. I may not have enough Nassarius snails stirring up the sand...
* Angels - I know that a tank should be up and running for 6 months before adding angels. Since most of the rocks and sand will come from the old system that has been "live" for more than 6 months, how long should I wait before introducing the angels into the new system? Also, should the angels be introduced last, or should the tangs be introduced last?
<S/b fine to add once the system is stabilized... let's say in a week or two>
* Skimmer(s) - Some sources recommend using 2 skimmers of different types for large tanks. What types would you recommend here? Any particular brands/models that you would recommend here?
<One of good quality will do... RK2, EuroReef, AquaC...>
* Wet-dry trickle with live rocks vs. using only live rock - I've
read/heard strong recommendations on both sides of this argument. What do you think would be best in this setup?
<The LR>
* The Big Move - My plan is to first fill the new system with RO/DI water to run and check for leaks, then mix the salt right in the system.
But then what? Should I gradually do daily water changes from the old system to the new system and gradually move live rocks from the old system to the new system (adding new cultured rocks to the old system) until the new system tests well?
<Mmm, likely once all is mixed, settled in water wise, mixing just once, some of the old water for the new... then next week, moving all the old into the new...>
Or would I be better off with a big bang approach -- i.e., after the new water is fully mixed and salinity/temperature adjusted in the new system, drain some of the water from the new tank, add all the new cultured live rock to the new tank and move all of the water and live rocks from the old system to the new system?
<This, with the one intermittent period>
This would then be the equivalent of a massive water change, since the livestock would have all of their old water and live rocks/sand, but lots of new water, too. Or is it possible that some water parameter may get out of balance? (The only inhabitants of my 120g that will need to make the move are 2 clowns, 3 Anthias, 2 serpent stars, the sand star, a peppermint shrimp, a skunk cleaner shrimp and various snails and hermits.)
<Best to mix, back and forth at least once...>
Sorry for so many questions. Thanks so much for your help (and for all of the great articles and FAQs on you website that have greatly helped my research).
<No worries, glad to conspire with you. Bob Fenner>

Re: Stocking Plan for 220 Gallon FOWLER Tank, esp. dwarf lion comp.  8/18/08
Bob, this is all VERY helpful. Thanks much. I'd also really appreciate your opinion on a modified version of the plan that would include a lionfish. I had given up on the idea of a lion in my 120g so that I could have more fish rather than a smaller group of bigger fish. In the 220g, it's worth reconsidering. Here's a modified stocking list (also updated for your prior input):
* Dwarf Zebra Lion (7")
* Rock Beauty Angel (8")
* Flame Angel (4")
* Coral Beauty Angel (4")
* Saddleback Butterfly (9")
* Pearlscale Butterfly (6")
* Blue Striped Butterfly (5")
* Purple Tang (9")
* White-Faced Tang (8")
* Bristletooth Tomini Tang (6")
* White Stripe Maroon Clown (6")
* 3 Lyretail Anthias (4.7" ea)
* Mystery Wrasse (4.7"?)
* 2 Diamond Gobies (6" ea)
This is a bigger fish load than the original plan, so would I now be in potential danger territory for aggression, or will they likely behave given the extra swim lanes provided by the island setup?
<All this could/should work... the Lion may eat the gobies...>
I'm assuming bio load would still be OK with a large sump/fuge, despite the fact that the lion is a messy eater, right?
<Yes>
Assuming I get the lion transitioned to only eating frozen food while in QT, will these other fish let me get a feeding stick to the lion without trying to intercept it so that he doesn't starve?
<Likely so>
I've seen the mystery wrasse listed anywhere from 3-5". Since I don't know the real size, is this safe with the lion?
<If the Lion is started small... this Pseudocheilinus is usually "smart" to avoid Dendrochirus, and lives more in and about the midwater rock work... the Lion and the gobies though... on the bottom...>
If not, would a radiant
wrasse (4.5") be safe?
<Safer>
Also, are the Lyretails and Gobies safe?
<Not entirely, no>
I know smaller fish would be at risk, but I'm not sure if any of these would fit in his big mouth.
<Oh, can>
I believe a Fathead Anthias is taller than the Lyretail while being just as long, so that could be an option (though just one male if I get this one), or are the other fish too aggressive for the Fathead?
<I'd skip on a/the Serranocirrhitus here... too likely to "get lost" in your setting. Bob Fenner>

Re: Stocking Plan for 220 Gallon FOWLER Tank 8/18/08
Thank you SO much! I'll skip the Anthias and Gobies. Maybe get a Goatfish or just rely on the snails and sand stars to keep the sand clean.
<Ah, good>
I'll get a larger mystery wrasse, let him get started in the tank first, then get a small lion. Thanks again!

FOWLR Stkg.   10/12/08
HI WWM crew
<Dean>
I'm starting a 5ft saltwater aquarium. FOWLR. With separate external filter sump.
The fish I want to get are as follows.
4 percula clowns
1 longnose butterfly
1 scopas tang
1 coral beauty
1 royal gramma
Are all these fish compatible and suitable for the tank
<Yes>
Are there any in the list that could prove difficult to care for
<Mmm, perhaps the Butterfly... I would place it last... giving the organisms on your rock, many going on to populate the substrate, opportunity to spread, stabilize this system... and do take special care in picking out the Angel... some specimens of coral beauties are very "rough"... almost impossible to "turn around" from their collection, handling, shipping damage... Do read on WWM re livestock selection, this Centropyge in particular>
Thanks a lot.
Dean
<Welcome. Bob Fenner>

Re: FOWLR lvstk.  10/12/08
Would any other fish be able to be added or would that be the maximum amount of livestock for that tank
Thanks alot
<... no such word>
Dean
<Others could go with adequately breaking up the environment... with rock, decor... B>
 would I be able to keep a coral banded shrimp in this aquarium?
Thanks
Dean
<S/b.>

Re: FOWLR lvstkg  10/14/08
thanks
The tank is 5' by 1' will this narrowness interfere with any of the fishes natural behaviour
<Yes, can indeed. B>

Tank-stocking agenda, FOWLR, 55  – 09/12/08
Awesome resource, everyone. Thanks for the invaluable information!
<Welcome>
Experienced freshwater/cichlid aquarist wading (sorry ;-) ) into saltwater for the first time.
<Ahh, zee plongee!>
I'm nearing the end of my cycling process in a 55 gallon set up. I have 53 lbs LR and about 2" (+/- 50 lbs) of a seeded LS mix (about 40% live, 60% non-living when I added it). My water quality is right on: ammonia = 0, salinity = 1.023,
<I'd raise this... to NSW strength... 1.025-6>
Temp = 77-78F and steady. Two small powerheads create some decent movement in opposite corners, both toward the center of the tank. My next step is a satellite lighting system then hopefully some inverts/fish which is why I'm writing.
My intentions/hopes are: 1 Maroon Clownfish
<Can become a bruiser... the only fish here in some cases>
(or 2 Ocellaris or Perculas), 1 Australian Scott's Fairy Wrasse, 1 juvenile Koran Angel,
<Mmm, no... not enough room>
1 juvenile Bursa or Picasso Trigger.
<Ditto>
I'd like to add a BTA as well and maybe a long-spined urchin or two.
<... wait off on these till you have more experience...>
My questions are 1.) When adding an anemone and clownfish in hopes to create a hosting situation, which should be added first?
<See WWM in future, but don't try just yet...>
2.) How 'mature' must a tank be before adding a BTA?
<Mature... a few to several months...>
3.) I know I'm probably hopeful beyond most experiences intending a Bursa/Picasso in a tank with a BTA and long-spined urchins; provided that the Trigger is small when introduced (2") is it at all likely that a.) it won't bother either or b.) the Clown will protect its anemone (obviously this assumes it takes the BTA as its host).
<Not going to happen in this small volume. I discourage your trying>
As of now I plan to introduce the fish in an order as follows: 1. Maroon Clown, 2. ASF Wrasse, 3. Koran Angel, 4. Trigger. Is this advisable?
<No>
When should I try the BTA or do you advise against it altogether?
<The latter>
I've asked several questions in one, I hope you can make sense of it in the format I've used. Thanks again for all the info. You've offered a huge amount of help in the process thus far and certainly will continue to do so.
Joe V.
<Keep reading for now Joe... I don't want you to get so bummed out from bad experiences that you give up the hobby. What you propose here won't work. Bob Fenner>

Re: Tank-stocking agenda, FOWLR, 55  9/12/08
Bob,
<Joe>
I appreciate the quick response. And thanks for the suggestions. Don't worry about my being put off by the info; I'm searching for the right information because at this point I prefer to learn by researching rather than (bad) experience.
<You are wise here>
For the sake of the process, the money spent and most of all, providing the proper environment for these guys.
I'll reconsider, keep reading and let you know what I arrive upon. Next time I write it me be re: 200 gallons ;-)
Thanks again.

<Welcome! BobF>

Wrasse Compatibility/Stocking - 55 gal FOWLR  9/18/09
Crew,
I'm currently in the process of planning my stock for a 55 gallon FOWLR tank. Obviously for any new tank there can be tons of options so while it's an exciting time, I'm committing myself to having the plan laid out before making any expensive purchases or costly stocking decisions.
Upon Bob's better judgment I've scrapped Plan A (Maroon, Fairy, Koran, Bursa) and it's back to the drawing board.
<Good>
I'm showing 0 Ammonia, 0 Nitrites, 8.0-8.4 pH, 1.026 specific gravity (upped that a bit a week ago on Bob's recommendation - Thanks again!)
10-20 Nitrates ppm. 53 lbs LR, 2-3" LS (~50 lbs).
A few questions in specific regards to Wrasses:
1. I'm strongly considering 2 species. A Sixline (Pseudocheilinus hexataenia) and a Scott's Fairy (Cirrhilabrus scottorum) (My LFS currently has a beautiful 4" Australian specimen; though it also has a beautiful 3-digit price tag.) So the question here is which should I introduce to the system first? The Scott's Fairy or the smaller, though
probably more feisty Sixline (2")?
<Mmm, what else is to go here?>
2. Also, I've seen a few references made on WWM as to QT and Wrasses. Should typical QT practices not apply to Wrasses? Should I just drip acclimate, dip and add?
<I would do the latter with these species>
3. I'd also like to add a Maroon Clown. Which should I add first of these three? Or is this a one-or-the-other situation?
<I would not keep a Premnas in this size, shape system with other fishes... It's too likely to bully them... to the extreme. Read here: http://wetwebmedia.com/marclncompfaqs.htm>
4. I understand the Sixlines offer a bit of 'housekeeping' by feeding on small LR inhabitants. Is a general diet of Mysis, Brine, et al. sufficient for the Sixline in addition to what the LR/LS already offers?
<Yes>
Thanks so much,
Joe V.
<Please... learn to/use the search tool, indices... on WWM. BobF>

New Tank Stocking – 09/08/08
Good day Crew,
<Eric>
Thank you in advance for your assistance. I read so much on a daily basis.. at times the words run together!
<Mmm... I try drinking less coffee and caffeinated diet sodas... getting up, away every hour or so from the keyboard... reflecting paragraph to paragraph, asking myself "what is this saying?">
I am setting up a new saltwater tank and just have a quick question. I have a bare tank (in the planning stages.. have yet to figure out filtration, etc. I have not bought any of the following livestock or the filtration system. It will be well filtered with high levels of mechanical and biological filtration, and will of course have a great skimmer.
Here is my proposed stock list:
1. Zebra Moray Eel (Gymnomuraena zebra)
2. Yellow Eye Kole Tang (Ctenochaetus strigosus)
3. Flame Angel (Centropyge loriculus)
4. Wrasse (Lunare, Blue, or some other related Wrasse)
5. Long Spine Urchin (Diadema setosum)
6. Turbo Snails (Turbo sp.)
<These last two may prove incompatible with the Eel and Wrasse>
The most important are the Zebra Eel and the Flame Angel.
<These two can co-exist fine together... the Gymnomuraena needs a good volume more... at least a hundred gallon system>
I am a bit concerned re: the Compatibility of the Flame and the Kole (will add the Kole first)
<These two should do fine together as well>
and I'm concerned about the Eel/Wrasse and the Urchin.
<You should be... too likely the eel will damage itself... the Thalassomas will eat them if hungry>
I have read that the Urchin has the long spines to protect itself, but I'm a bit doubtful.
Again, thank you very much for your assistance!
Eric
<Do keep reading, accumulating notes for now... This is the best path to assuring future success. Bob Fenner>

Re: New Tank Stocking, FOWLR  9/9/08
Hi Bob,
<Eric>
I really appreciate the help. I've been doing a ton of reading, and actually (after writing) saw a picture of 2 Lunare Wrasses dismantling and eating an Urchin, so that's a no go. Also, I wouldn't want the clumsy (and somewhat vision impaired) Eel getting hurt by the spines.
<Good>
I forgot to mention that I have a 75 gallon tank, so I think that the Zebra eel will be out.
<Agreed>
I've read a lot of conflicting info.. some say 75 gallons is the minimum, some say 100 gallons.. I tend to think it grows too large for my 75 and will be a messy eater.
<See my article re this species on WWM...>
Here's my updated list, in order of introduction.
Can you give a moderate critique? (I promise this won't be a recurring theme!)
<I can, will>
1. Small shoal of Damsels (lesser aggressive types, such as the Yellow-Tailed Blue or possibly Chromis, though I bet they'll get picked on by the Wrasse)
2. Kole Tang
3. Snowflake Eel (friendlier than most eels, and smaller than Zebra)
4. Flame Angel
5. Lunare Wrasse
<This mix could work... as you state/hint, the Lunare may prove to be too raucous...>
All these previously mentioned fish will be added at about a rate of 1 per month or so, and I'll buy them small.
Once the fish start getting bigger, I'll relocate the Damsels to other tanks ( I have other homes for them).
<Ah, good>
Does this seem like the correct order? Also, slight possibility of the tank being overstocked?
<I'd place in the order you list above>
Thanks again, I honestly appreciate it!!
Eric
(P.S... in my research, I went to YouTube and saw some videos of my prospective fish 'in action'.. good place to go for additional insight, although I wouldn't trust their information.. I saw a video that had a Bamboo shark and about 1/2 dozen other small- too large fish in a 75 gallon tank! awful..)
<Thank you for this. Bob Fenner>

FOWLR compatibility question?, 9/4/08
First off I have to say I love your site and use it regularly to research new fish and also to gain new information.
<Great>
I currently have a 46 gal tank with about 75 pounds of live rock and also have about 50 pounds of live sand. As
of right now I have one flame cardinal and a dwarf or falco hawk and I was thinking about adding one or two more fish to my system in which I would like to get a Valentini puffer and/or a Picasso trigger.
<The Picasso gets way to big for this tank, the Toby may work, but I would be concerned with the Hawkfish, which it may nip due to it's sedentary behavior.>
I have been looking for a hardy fish that is also very active and entertaining to watch and happen to come across these two at the my LFS and was wondering what your opinion would be on these two fish?
Thanks Chris
<Definitely no on the trigger, and I would probably skip the Toby as well. Perhaps on of the smaller wrasses or a pair of good old clowns would work here. Lots of other choices available as well.>
<Chris>

FOWLR System Stocking – 08/29/08
Dear Crew,
<<Steve>>
I have a Sea Clear system II 125, already aged 3 yrs with a 1 mandarin, 1 yellow tang, 1 blue tang, 7 chromis, 1 imperator angel, 1 Pseudochromis, 1 cleaner shrimp, 1 clown, 1 coral beauty, 1 emerald crabs. All doing very well. Are these guys compatible with a Naso tang and Heniochus acuminatus butterfly fish?
<<Compatible, yes…but “too much” for this already well stocked tank. Best to pass on these additions and allow the fishes you have to continue to mature, grow, and live with some room to do so, in my opinion>>
Thank you,
Steve
<<Happy to share. EricR>>

Stkg. 75 gal., FIWLR  7/20/08
Hi all,
It's me again, sorry about all the stocking questions all the time, just don't want to over crowd, and I still have fish I would love to have if I could. Right now, I have a Pink Skunk Clown fish, a Six line Wrasse, a Flame Angel, 3 Green Chromises, a Lawnmower Blenny, a Fire fish, a Chalk Bass, a Serpent Star, a Skunk Cleaner Shrimp, 2 Feather Dusters, 2 Emerald Crabs, a Sally Light Foot, and assorted Mushrooms all in a 75 gallon tank. I have a Remora Pro, and an Emperor 400 that I only run with 2 generic cut to fit filter pads, and 80 lbs of live rock. I do a 20% water change, replace the filters in the Emperor, and clean the protein skimmer pre filter every Friday morning.
I wanted to know if you think this is maxed out. What I still really like for fish are, another Pink Skunk Clown, a Fairy Wrasse, another star fish, and or more Mushrooms. I would also like to take out the three Chromis and give them to a friend. Do you think I can add any of these to my tank with/without taking out the Green Chromises? And if so, which ones?
Also, how would suggest getting the Green Chromises out of the tank? Aside from taking the whole take apart. And last, how often would you suggest giving the whole protein skimmer a vinegar bath, to clean out the inside.
Thanks again,
Marc
P.S. Do you think feeding the fish a half of cube of frozen food once in the morning and once at night is sufficient, or too much?
<I do not believe your aquarium is maxed out. A 75 gallon tank is large enough for fish such as clowns, fire fish, etc. You may want to add a tang such as a yellow or purple, maybe even a bristle mouth tang such as a Chevron or Kole for algae control. I would also clean the protein skimmer as it becomes full with waste. Hope this helps, IanB>

Stocking question, Marine 7/4/08
Hey Guys,
<Hello>
I really enjoy the site, lots of great info there!
<Thanks>
I have some questions about the stocking of my tank, and what you think of it so far. I have a 30 Gallon saltwater system, with 35 pounds of live rock, a Prizm Skimmer, (rated for 100 gal)
<Does not have a great reputation.>
two smallish powerheads for circulation. I have finished adding fish to it, I added them over a period of a few months, one or two at a time. The order went as such 1 Ocellaris Clown (Genghis), followed by two more a few weeks later (Kublai and Attila) as I was told that adding just one more would lead to one of them probably killing the other.
<Actually 2 will most likely pair up and kill the third as they mature.>
The cleanup crew came after that, over a period of a few weeks. The cleanup crew comprises 2 scarlet hermits, five tiny blue legged hermits, five neisseira
<Nassarius?>
snails, and a Monaco shrimp (Paul). Finally I have added a scooter blenny and a coral beauty angelfish.
<Both of these need larger tanks, the angel will outgrow this tank and the scooter "blenny" (really a dragonet) will not be able to find sufficient food.>
I don't plan on adding any more. The fish are all eating well and swimming around fairly energetically. The clowns have found a niche by the heater, and the Angel sits behind one chunk of live rock most of the time, coming out and swimming around every now and again.
They come out a lot more during the day. Am I overstocking this tank?
<Not really overstocked, but inappropriately stocked in my opinion.>
Every other site I have found states that a 30 gal tank should be sufficient and my LFS said it should be fine, but I don't want the fish to be unhappy so want to check as your site suggests a larger tank for what I have.
<I would agree with what you found on our site.>
I am also having a lot of algae problems... though I was told this is normal for a new tank... I'm getting brown algae, lots of green hairy algae, and following that a but of this nasty purple goopy stuff that bubbles a lot (I'm guessing Cyanobacteria, so I try to clean it out when it happens).
<Its common for this to happen in new tanks, but you want to control it as best as you can since it is quite difficult to remove once it has gotten a foothold.>
It usually comes back a few days after I've cleaned it off. I do a 3-5 gal water change every couple weeks, and my water chemistry is as follows S.G 1.026, pH 8.3-8.4, Alkalinity is in the normal range, Temp 78-79 F, Nitrate almost 0, Ammonia is less than .25, but above zero, though this is a few days after adding the last fish so probably doing a little cycle of sorts.
<Watch this very closely, ammonia is very toxic even in small amounts, be prepared for extra water changes.>
Should I expect the algae to go away soon, or should I try switching to RO/DI water?
<I use RO/DI, removes some guesswork, but time will tell if you need it or not.>
(Currently use tap water but it apparently has no nitrate, phosphate etc when I tested it).
<Good>
I also cut back on the amount I feed them, I feed them New Life Spectrum flakes with garlic, some green Nori seaweed, and mysis shrimp (frozen) for some variety.
<May want to feed every other day for a while to get the algae under control.>
I do hope to eventually add some soft corals too.
Does this tank have a chance of succeeding?
<You have some stocking issues, but the basic setup has a good chance of success.>
I'd hate for anything to die or even suffer here. Thanks so much for your help. I have looked over a LOT of your stocking suggestions etc, but nothing that really addressed my specific situation.
Eric
<I would look for new homes for 1 of the clowns, the angel, and scooter blenny, then find a couple of more appropriate fish.>
<Chris>

Aquarium Sizing & Such, Marine Stocking 6/22/08
Hi, I have a kind of silly question to ask. First, I have 10+ years of freshwater experience, 4 years of brackish and 1+ years of marine. So my basement looks like a fish store, lol. Anyway I would like to set up a show tank, preferably about 200 gallons. Currently I only have damsels and clowns in FOWLR systems. I've learned not to trust coral. The fish I would love to have would be
1 Dwarf Zebra Lionfish
1 Blue Dot Puffer
1 Powder Brown Tang
1 Metallic Foxface Rabbitfish
3 Banggai Cardinal Fish
1 Coral Beauty Angelfish
Now I have friends who keep fish too but not really of the kind I'm looking for. One problem is some say yes and some say no. One problem would be that the Blue Dot Puffer would nip at the Dwarf Lionfish, but one of my friends say that as long as the puffer is fed, he won't be a problem.
<Not often related to feeding, more along the lines of general aggression/territorial issues. Depends on the individual personalities of the fish.>
Is that correct, or do I owe my friend a smack?
<Smack them anyways.>
Another would be that the Lionfish would eat the Banggai Cardinals, but again, I've heard if there is enough rockwork that they are fast enough to not become meals, and if the lionfish is fed right, there won't be a problem with him anyway.
<If they can fit in his mouth the lion will most likely try to eat it, and it only has to get it right once.>
Is that all correct? I've also looked up how big an aquarium should be, but it only comes up per fish. If it's all added up, it should be a 350 gallons. That just seems like it would be too much open space to not enough fish.
<Not really possible in my opinion but I know what you mean.>
So would it be ok to place them in a 200 or 250 gal?
<This would probably work, the tang needs the most room here, at least six feet of straight line swimming room.>
Is 350 the minimum? I want to move my hobby upstairs, that is why I want a show tank. I'm just afraid a 350 gal (even a 250) might be too heavy
and bust through the floor.
<Definitely a concern.>
