hi crew
<Hello... where's your punctuation?>
I have a 10g tank setup ( small i know, this was just to make sure i could cope with the hobby before splashing out on a bigger system)
<Too small to have much chance of success>
in the tank i have about 4kilo of live fijian rock a blood shrimp and a fuzzy dwarf lionfish,
<...>
i feed mysis shrimp once a week,
<... Let me stop here. Please read:

temp 25 salininty about 1025 with a trickle filter, the system has been running for about 3 months. the "problem" is my blood shrimp which has molted regulary ( once a month) after his last molt has since turned
white/red nearly pink, was just wondering if this is normal and why? this has happened please help, everything else in my tank seems to be good.

35 gallon Hexagon Lighting, stkg., reading  11/18/09
Hi again,
< Hello >
I have just finished reading about the lighting for my aquarium and I am still not sure of what to buy. I have a 35 gallon hexagon which I purchased years ago. I probably should have bought a new rectangular one after coming across the problems with the lighting I'm encountering.
Anyway, I have live rock, a tang,
< Your tank is much too small for a tang. >
goby yellow clown, Basslet, and Ocellaris clown fish, serpent starfish, peppermint shrimp, snails, one emerald and one porcelain crab, also one anemone.
< Overcrowded. Also, a 35 gallon is borderline for any type of anemone. >
I would like to have two L.P.S.'s eventually. The top of my tank is only about 20 inches across. I have a compact fluorescent on there now that is extremely old and the company went out of business so it has been very hard for me to find a lighting fixture that will work( one that is only 20 inches across). The back of the tank has a protein skimmer hanging on it so there is no room for a clip on light, unless the clip is only 2.5 inches long.. After that being said..my tank is 18 inches deep and the top of the live rock is 6 inches deep. So the corals would be anywhere from 6 - 18 inches deep. I don't want to burn them up with too strong of a light but do want to give them what they need. What can you suggest,,, please help. I have thought about changing the protein skimmer also to try to add room for the clip on light, but no luck as of yet..
What do you think I should do???? Thank you so much for your help and time..
Cindy
< Normally I suggest T5 lighting for a tank of this size but because of the shape of the tank , I would look into one of the many 150 watt metal halide pendants on the market. Simply hang the light from the ceiling and raise or lower the light as needed. As an option you could look into a 24" 4 bulb T5 light. I know that the legs on Current lights and a few others have the ability to slide in , fitting smaller tanks. Not the most attractive way to go but very functional. Either option would serve you well. GA Jenkins >

Stocking a 37/Stocking Level/Marine Set-Up 10/27/09
Hi!
<Hello Alissa>
Thank you for taking the time to answer my question.
<You're welcome.>
I’m finally setting up my first fish tank and I’ve never been so excited. Even though I’ve never had a tank before I decided to dive right in with a FOWLR. I’ve been reading a lot and also have my expert sister for guidance. I have a 37 gallon (tank is 24”H x 30”W x 12”D) to which I’m planning on adding about 30-35 pounds of live rock and about 2-3 inches of live sand from fine to rubble, 1 protein skimmer & 2 filters (along with other necessities) to support 1 pistol shrimp, 1 smaller shrimp goby, 1 smaller serpent or brittle star, 1 emerald crab (maybe), 3-5 Green Chromis, 2 Firefish, and 1 Royal Gramma (maybe). Do you think this will be a good mix?
<The chromis' are aggressive feeders and likely will not be enough food available for the more timid Firefish. Firefish are best kept by themselves or with fish of similar personalities/disposition. Do read here. http://www.wetwebmedia.com/drtfshcompfaqs.htm>
I will of course be adding them gradually after quarantine in a separate 2.5 gallon tank.
<This tank is too small for a QT.>
Also, should I add the 2 Firefish first and then the chromis or vice versa? I’ve read that the Firefish will be less territorial but the chromis will be hardier in a beginning tank. Then I will add the gramma (maybe) followed finally by the goby. Thanks again for your expert advice!
<A better choice would be two or three Yellow Tailed Damsels (Chrysiptera parasema) to go along with your shrimp/goby combo and Royal Gramma.
The Royal Gramma should be the last fish you add and the shrimp/goby combo being the first. James (Salty Dog)>

Compatibility (Help) 10/8/09
Hey all,
<Jonathan>
I am turning to you all for some advice. I have set up my 29 gallon nano tank for about 6 months now, and finally added my final livestock (Tail Spot Blenny) to my tank. I currently have a pair of false clowns (1
black/white and 1 orange) and one Royal Gramma. The 3 have been living in peace together for about 3 months now.
Since its been so long, I forgot that the most peaceful fishes should always be added to the tank first, and the Gramma seems to be bothering the blenny. I actually saw the Gramma take a pretty good bite of the blenny as he sticks his head out of his "hole". Unfortunately, he picked his spot right in front of the gramma's "nest" and the blenny is cornered in it seems. Its only been about more than a day but every time the blenny tries to leave his "hole" the Gramma scares him back in. Will this continue?
Should I be worried about the blenny? Also, the clowns are very curious, but I don't think they would do harm the blenny? Any suggestions?
<Yes, in lieu of the tank being on the small side and easier to work with, carefully rearrange the rockwork which will initially eliminate territorial behavior. We are hoping that after this remodeling, their new territories
will be much farther apart and hostilities will end.>
Your comments and advise are always greatly appreciated. Thanks in advance.
<You're welcome. James (Salty Dog)>
Sincerely,
Jonathan Tan

29 gallon stocking question
BioCube Stocking Options, First Time Reefkeeper - 09/22/2009
Hello guys,
<Ahoy!>
First thank you for all the great website. I plan on getting my first marine aquarium soon and I have decided on a 29 gallon tank.
<It is my opinion that this is much too small a tank for a first foray into saltwater. It can be done.... but larger is better. If you do opt to move forward with this system, please consider keeping your stocking density
quite low.>
The Oceanic BioCube if that is important.
<One of the nicer all-in-one tanks, but do keep in mind that, with a tank like this (as opposed to a generic tank with regular components), you are limited to what it comes with, and what modifications you can do within the confines of the space provided in the system.>
I plan on the tank starting out as a fowler and slowly progressing towards a reef tank.
<Tough to do in an unforgiving amount of space/water, but entirely possible. http://www.nano-reefs.org has a section about modding all-in-one tanks to make suitable reef systems; the BioCube has quite a bit of
discussion there. You might want to check it out.>
I was planning on stocking the tank like this:
16-20lbs of live Rock (Fiji)
<The more the better - as long as there is space.>
20lbs of live sand
<Go with an inch or less of substrate, unless you're doing a DSB, which I think is not possible in the BioCube. You needn't spend the extra cash on live sand; it will become "populated" with organisms and bacteria from the live rock.>
Ocellaris clownfish (Amphiprion ocellaris) ( I was also planning on using him to cycle the tank. Is the species hardy enough?)
<No, absolutely not a good plan. This is a great fish for this size tank, but no, do NOT cycle with this or any other fish. You're planning on live rock, yes? That alone will cycle your tank. Please read more, on WWM and elsewhere, on cycling, with live rock and otherwise. Cycling with fish is unnecessary, harmful and damaging to the fish used, and really not a good or easy way to cycle anyway.>
Six Line Wrasse (Pseudocheilinus hexataenia)
<I, personally, wouldn't keep this in so small a tank. They're surprisingly active, and will use all the space they're given.>
Royal Gramma (Gramma loreto)
<Same as the wrasse.... though many would keep a gramma in this size/shape tank. It could work. Bear in mind, though, that this guy will be a touch aggressive, and may very well outcompete other fish for food in such a small tank. I would NOT keep it in the same small system as the Firefish you list below. The Firefish won't stand a chance for food.>
And one Purple Firefish (Nemateleotris decora)
<An EXCELLENT option for a small system - and one of my all-time favorites!>
or a Flame Hawkfish (Neocirrhites armatus) I hear that the Hawkfish may fight with the wrasse.
<Nix the Hawkfish - they have appetites like you wouldn't imagine, and will likely eat the crabs you mention below. They're also a touch nippy. I would not keep this guy with the Firefish.>
6-8 blue legged hermit crabs(Clibanarius tricolor)
<These are fine.>
and some assorted snails.
Would this stocking plan work?
<As above.... Might you consider a pair of clowns, and a pair of Firefish, and omit the other fish? The Firefish will fare better in a pair, and these four should get along well in the space of this tank. It would also
make for a rather attractive display. You might also consider a couple of Lysmata cleaner shrimp.>
I am fairly certain these are all reef safe.
<Depends on what you call reef safe. The flame Hawkfish is quite adept at eating shrimp, crabs....>
I also heard the Clownfish may do better with a mate, but I think that may be too many fish.
<The list you provided is "too many" in my opinion, considering the aggression of and space used by the fishes you list. There are many, many other options out there of smaller, less aggressive, and less
space-consuming fishes. Four fish might not be too many, but the activity level and aggression of the fish must be taken into consideration.>
Is it better for me to introduce all the fish at once after the tank has cycled or should I add them over time and if so what is a safe introduction plan?
<As you list.... The hawk and gramma would be the final introductions, with the Firefish and clown preceding them by two weeks or more. But again, I really don't think your list would be successful long-term, and
I'd hate to see that Firefish starve.... I trust you will be quarantining the fish prior to introduction....>
Thanks,
Cory Prewit
<Good luck with your first foray into reefkeeping! I hope you'll find it to be very rewarding. Don't stop reading, and keep planning. You'll find success. Wishing you well, -Sabrina>

Green star polyps 09/14/09
I have a small 7 gallon saltwater tank that was given to me about 4 months ago. The tank has 1 spotted dotty back, 1 tube anemone, 5 assorted hermit crabs, 7 snails, 5 star polyps and 2 mysterious snails I was told are conchs by fish store.
<My friend, you have far too many animals in this "tank." Please remove all but the one fish, star polyps and maybe 2 *small* snails.>
When I first bought my star polyps I had around 30 on a piece of live rock.
After 3 weeks I noticed they were diminishing. I checked my water and the levels seemed ok. To note due to small tank I change the water on a regular basis as instructed by fish store. They said more if levels get to high but 10 percent a week. I moved them to a lower flow area and noticed these conchs followed and seemed to be pulling them off the rock.
I have isolated these conchs and now my stars are not disappearing. When I asked the fish store they said a conch will not hurt the polyps. My question is what would hurt the polyps?
<Likely the hermit crabs, among other things... again, your system is overstocked.
Cheers,
Sara M.>

Re: Green star polyps, Sm. SW stkg.  – 09/14/09
Crabs are bad news in small tanks. The store didn't lie to you. They will eat some algae, but (in such a small space) they will also pick at everything else too. As for the tube anemone... is there any reason you can't just get a bigger tank? The tube anemone might be ok for awhile, if you're really careful to keep the water quality up. Very experienced aquarists could probably do this. But 7g is just ridiculously small for a reef tank... very unforgiving. Do you think you could upgrade to at least a 20g tank?
Best,
Sara

Stocking A 29 Gallon BioCube 9/9/09
Hi crew.
<Hello Jessica>
Thanks for your site and all of the invaluable info.
<Welcome.>
I purchased a 29 gallon BioCube and am currently in the process of cycling it with about 40-50 lbs of LR and 35 lbs of live sand. Everything on the tank is stock except I added the Oceanic skimmer which seems to be working fine. I am a ways away from adding any tank inhabitants but I have done some research
on specific fish and am looking for your expert opinion. I have a 2-3 inch sand bed because I am fascinated by the shrimp/goby pairs and am thinking about getting a pair. Would they be ok in a tank this size with a sand bed that deep?
<Sure, and an interesting addition.>
I am also interested in a clown fish but some seem to get rather large for this tank. What would you suggest? Clown or no clown?
<Twas me, I'd go with no clowns, but two Ocellaris Clownfish would work out.>
And which one? The other fish I like are Firefish and the Bicolor Blenny (purple front with a yellow tail). Would these fish be ok in my tank?
<The Firefish does much better in groups of three or more and in lieu of this, would not be a good choice for your bio cube. The blenny would be fine, but keep in mind they can easily exceed 3 inches in length.>
Which ones are ok, if any, and what combo can I have?
<The above are fine, but keep in mind, four small fish is about the maximum load for this system.>
Any other suggestions on fish selection would be helpful.
<Look at some of the colorful Dottybacks such as the Neon and Sunrise Dottybacks.>
Thanks for the help :)
<You're welcome. James (Salty Dog)>

Re Stocking A 29 Gallon BioCube 9/9/09
Thanks for the help. Which shrimp goby would you recommend?
<No specific recommendation, but I like the Yellow Watchman Goby.>
And as far as Firefish go I have read on your site that they don't do well in groups..Maybe I am confused..
<You are not, Scott Fellman mentions this in Dartfish FAQ's, but on the other hand Scott Michael (Reef
Aquarium Fishes) mentions otherwise. My opinion is that they do better in groups and should not be kept with aggressive tankmates as they will usually hide and refuse to eat. If I were to choose Firefish/Dartfish, I would not include clownfish due to their more aggressive feeding habits, likely
leaving the Firefish with unequal portions of food. A good place for Bob's opinion/thoughts.>
<<...? The more popular species of Microdesmids kept by hobbyists are almost always found in twos/pairs in the wild... Some, e.g. P. evides, in social groups... This is stated on WWM. BTW, none are suggested for such small volumes as this. RMF>>
Would I be able to have the two clowns you recommended and other fish as well? The clown pairs can be pretty territorial right?
<As I mentioned, no more than 4 small fish including the clownfish. The Ocellaris Clownfish can be
aggressive, but is generally limited to conspecifics and/or other damselfish with similar personalities.
James (Salty Dog)>

Re Stocking A 29 Gallon BioCube 9/10/09
Ok thanks.
<You're welcome.>
And for part of the cleaner crew would a scarlet cleaner shrimp be ok?
<Would be fine.>
Do the clownfish have to be in pairs?
<No. James (Salty Dog)>

Corals... sm. SW stkg. issues  08/02/09
Hey guys,
Love the informative website! My tank is doing well thanks to your advice regarding stocking my tank. =) I finally took the plunge into corals, and wanted to get some advice on how many hrs a day should the lights be on for maximum health?
<10hrs to 14hrs, ideally. However, there's some flexibility if you have different kinds of lights. For example, I know some people who have both metal halide and VHO, who keep the metal halides on for 6 to 8 hours a day, the VHOs on before and after the MHs come on and off.>
Currently I have some polyps and one xenia and though they do open up, not quite as much as in the local LFS. I have placed them in the sand to acclimate them to the nano cubes lights, which should be sufficient for these corals. Also, my snails and hermit crabs seem to always be on their rock/frag which I know will cause the corals to close. Is this something I should be worried about? I have 3 dwarf blue hermit crabs and some nausarias/cerith/trouchas snails. Any suggestions on how to give the best care to the corals?
<In a nano cube? Your biggest challenge is going to be keeping the water quality high enough. Do plenty of water changes, be prudent about matching temp/pH/etc. of change water. Run plenty of carbon, keep your filter clean. Don't overstock with fish... you know, just keep the water quality as best you can. If you do so, these corals will likely "forgive" less-than-ideal lighting (once they adapt to it).>
Thanks again.
Jonathan
<De nada,
Sara M.>

Tank livestock, sm. SW  08/02/09
Could I put a clown fish a blue tang and a yellow tang in a 38 gallon tank?
<No. Please research these fish here on WWM, elsewhere. Once full size, these will be too much bioload for a 38g tank. Also, tangs need *at least* 55g. -Sara M.>
Re: Tank livestock 08/02/09
Not even just one of them?
<One of what? One Tang? No... not in a 38g. You can keep a clown fish in a 38g. -Sara M.>

Re:... Stocking 38 08/02/09
Hey crew! I just added my first fish yesterday to my 38 gallon tank a clownfish and a chromis I want to add a small tang I have read they will grow to fit their tanks but on another note could u name some other good
fish for my size tank? Pls answer I haven't received answers to many of my past questions
<My friend, you have received responses (you even responded to one of them). And again, no, you can't/shouldn't keep a Tang in a 38g tank. No, they do *not* grow to fit their tanks! With only 38g, you should stick to fish that are smaller and don't need a lot of swimming room. Some good choices might be gobies, blennies, clownfish, etc. Please see here:
http://www.wetwebmedia.com/marine/setup/marsetupindex1.htm
Scroll down, look under "Small Marine Systems (< 40 gal.)."
Cheers,

Re: Stocking 38
Alright thanks and the one I replied to about stocking it was after I sent the message saying I didn't get a reply but thanks!
<Ok, cool>

Shrimp Question, comp.   7/31/09
Hey all,
<Jonathan>
I have a 24 gallon nano cube with about 20 lbs of live rock. I currently have 2 cleaner skunk shrimp and was thinking of adding either one or 2 blood fire shrimp.
<Mmm, I wouldn't... not enough room here>
Will they coexist together?
<Maybe not; particularly during moults>
At first, I got 2 cleaner shrimp because they are more active and less shy than the fire shrimp. However, my 3 yr old son loves the fire shrimp and I would love to get one for his birthday this weekend. Will they
coexist together?
<...>
Will it be more beneficial if I get a single red blood or a pair? Current tank mates are one orange and one black/white clown and a royal gramma.
Thanks again for all your help.
Jonathan
<I'd stick with what you have or trade them for the L. debelius. Bob Fenner>

My tank. Sm. SW stocking issues... reading    7/30/09
Hi Crew,
After 5 years with a 10 gallon I upgraded to an Aquapod 24 gallon and moved my fish and corals to the new tank back in January. The new tank has an hob skimmer and 65 watt pc's 12k daylight. Added all new sand (sugar texture) and rock. The fish I had were a spotted cardinal, a neon goby and a clown goby. The coral was candycanes. I added two heads of frogspawn and 10 heads of a hammer plus a four inch square Favites. I added a Firefish
<Is a social species and needs more room than this>
and a chalk bass. Then I added a false percula and 2 more Firefish. One Firefish lasted a day and the other about 4 weeks. Then my 6 year old clown died. So Now I had the spotted cardinal, neon goby, chalk bass and clown. The clown is not as docile as my other fish even though he is just about and inch so I was thinking I should remove him. But he was so active he made the others come out and swim in the open so he stayed.
Then a couple weeks ago I saw some fish on sale and I got a blue chromis, a royal gramma, a red spotted Sandperch and a citron goby.
<... troubles>
I had actually ordered a yellow clown but the citron is what came and it is much bigger than what I expected. So what is my rational for all this. The Sandperch stays on the bottom (except during feeding). The cardinal hovers but does not move around much and he is larger than the others. The Firefish and the neon goby are similar in how and what they do but seem to get along.
The blue chromis is an open area swimmer near the top and the chalk bass is an open area swimmer but more towards the middle. The Gramma goes around but tends to stay close to the rock. The citron goby just parks himself on a Candycane and watches everyone else. However he is not eating like he should. I have seen him take something but not regularly. His eyes look a little cloudy and I am wondering if he has a problem seeing. The percula clown is all over the place and during feeding fights with the chalk bass. That is the only aggression that I see. So there are a lot of fish they have different tendencies so my feeling is it should work. I will remove the clown. One of my concerns was where they would all go when lights are out so I made sure there were plenty of hiding places in the rock. I do have Cyano but it is not out of hand and is mostly on a few patches of sand which I stir up once a week. I assume you think I should remove some other fish as well. What would you suggest.
Thanks

Condy Anemone 7/14/09
We have just started our first saltwater aquarium and purchased a Condylactis anemone.
< Anemones should never be placed in a newly established aquarium. 6 months to a year minimum. >
It is pink/white and has purple tips. I have read a lot about these anemones but still have a question or two about it. First here is some information on our tank. We decided to start small. So we have a 20G tank.
< Too small for this animal. >
It's inhabitants include:
1 1/2 inch substrate
6lbs dead rock
10 1/2 lbs live rock
5 hermit crabs (red legged)
3 snails
1 Skunk Cleaner Shrimp
1 Black Brittle Star
1 Royal Gramma
1 Lawnmower Blenny
< Can become aggressive in small environments. Especially as they age. >
2 Percula Clowns
1 Pencil Sea Urchin
< Could cause injuries to the anemone. >
1 Condylactis Gigantea
(We also have some Ricordea, a few tiny feather dusters and 5 teeny tiny sea stars that came on live rock) (Not sure if I spelled everything right! sorry)
< Tank is overcrowded. I would remove at least 2 of the fish. I would suggest keeping the Perculas.>
The only thing that I know about our lighting is that it is 15watt fluorescent. I do know that anemones need strong lighting.
< This is not nearly enough lighting. >
I target feed the anemone a small piece (1/4 inch or smaller) once a week and feed the tank a 1/2 cube of mysis shrimp morning and night. My water quality is excellent...1.024,
< I would slowly raise this to 1.026 >
8.2. 76 degrees, 0 for all levels it should be and so on.
After having the anemone a week now it is still "free floating" in one spot in the tank. It has not attached it's foot anywhere!
< This is not a good sign at all. >
Questions:
Is it normal that it hasn't attached yet?
< Absolutely not. This is a sure sign something is not right. >
Should it attach to something or will it always float?
< A healthy anemone should attach fairly quickly. >
Is my lighting good for this anemone, or do I need more?
< Your lighting is no where near enough. You should look into a 4 bulb T5 setup. Look for one with individual reflectors. You should also increase the feedings to help supplement the poor lighting. >
Also my anemone keeps "deflating" and "inflating", I know this is normal because it has not been in the tank long but do you know how long before they start to stay "inflated"?
< The inflating in deflating could just be the animal expelling waste. >
I really love this animal, it is SO gorgeous and want to do anything I can to make it happier. We are in the process of getting a bigger tank.
Thanks for any help you can offer!!
< A bigger tank is a good step but lighting is an immediate need. If a new light fixture can not be purchased quickly , you may want to consider returning this animal until you are more prepared to care for its needs. GA Jenkins >
