Clown fish how soon  6/4/07
Hi, I have clown fish in a 10 gallon tank with a cleaner shrimp. and wanted to know if I could put it in my new 30 gallon tank I ran it for 4 days and on 5th day put in my 3 stripe damsel.
<... may be troubles with these two here in such a small volume>
Is to soon to put my clown fish and cleaner shrimp in yet. And also is it to soon to put a baby clown trigger.
<No...>
I know this tank is not that big but I will be getting a 125 gallon tank soon.
<Then wait till you have this system up and going>
And don't know when my LFS will be getting baby clown triggers in again.
Thank you

Questions regarding nano reef (5.5g AGA): lighting and compatibility. Small Tank With Big Plans   5/25/07
Dear Crew,
<Scott F. your Crew member tonight!>
I'm not sure who will be the one reading this letter, but thanks in advance to that helpful person! I have a few questions; any help would be greatly appreciated. My system is
an AGA 5.5g nano reef.  I would like to keep the following:
   - Mushrooms galore
   - Purple cap (and similar corals)
   - Pulsing Xenia
   - Finger Leather
   - Yellow Polyps
   - Various zoanthids
   - Dwarf Seahorses (couple)
   - Peppermint Shrimp
   - Scarlet Leg Hermit Crabs
<In my humble opinion, this is too many corals of too many different types in too small a body of water. You'll have long term problems with chemical interactions between the various corals, particularly the Finger Leather and the Montipora (I assume that's what you mean by "Purple Cap"). In a system this small, I'd limit myself to one or two corals. Zoanthids would be a nice choice, because you could get a few different color varieties in this small space. Or, the best choice would simply be Xenia. They add movement, interest, and grow rapidly.>
After doing extensive research, I confirmed that all of the animals I picked are compatible with dwarf seahorses (except Zoanthids, of which I am unsure).
<I am not aware of any danger they would pose to the Seahorses. Although the crabs are generally inoffensive, they can stomp on and irritate your corals. If your dealer or other source for these crabs mis-identifies the species of crab, you could end up with a potentially dangerous one...Just something to think about when considering keeping crabs with Seahorses.>
Formerly I wanted to keep a blue clam, but after reading through
the FAQs, I found that the clams are best left for larger aquaria.  Some people also said that Linckia Sea Star (Blue) also need larger aquaria to survive, but I would like to get expert advice from you regarding that matter.
<Avoid the Linckia at all costs! They typically require large, long-established systems with large areas on which to feed on detritus, etc. A small system will simply not provide the necessary food sources for the sustainable husbandry of these creatures.>
My second question pertains to lighting.  I searched for days for
appropriate lighting for an AGA 5.5g.  While I love DIY projects, I've got two DIY projects queued, not to mention studying for GRE's and what not, so this is a bad time for another DIY.  Would the 20" 1x28W Coralife Aqualight hood w/ 50/50 be a good choice, or do you suppose I must go with higher intensity lighting (e.g., the 96W variant of the Coralife Aqualight)?
<Depending upon the photosynthetic animals that you'll be keeping, this could vary widely. For versatility, I'd probably opt for the 96 watt system.>
(Since the AGA 5.5g tank measures 16 inches long, there are not many lights that can neatly fit that are also appropriate for a nano reef.) At first, I wondered if it would be a good approach to get the 96W simply as a precaution in the event of an upgrade to say, a 10g tank.  In that light, would it be a wise maneuver?
<As above, I'd also opt for the higher wattage light. However, there are more and more small lighting systems coming to market all the time as "nano reefs" gain in popularity. Do check some of the e-tailers out there for what's new in nano lighting systems.>
Again, thank you very much.
Faithfully Yours,
Jason C. Wang
<Good luck, Jason! Hope your system is very successful! Regards, ScottF.>

Turbos in a Picotope   5/24/07
Hello, I've asked a few questions before and they have all been answered very quickly and completely.
<Glad to hear!>
So thanks.
<Welcome!>
I have 2 Turbos and 2 hermits in a 3-gallon Picotope. Questions are the Turbos and hermits have been working over time to rid the tank of unwanted hair and other algae. And doing an excellent job.
Are these cuc <???> going to consume their food source?
<Hermits are generally scavengers and typically aren't too picky. The Turbos will need sufficient microalgae to survive.  I would not add any Turbos to your current setup.>
I would like to get a cleaner shrimp or coral banded also, just want to know if they will have enough to eat.
<The shrimp will not compete with the Turbos for food.  Food and your water quality will likely be more of an issue in such a small system.>
Pico will eventually have mush,<mushrooms and mush?> polyp and other soft corals,
<Various Cnidarians in such a small system will likely cause problems with allelopathy. Please research each coral's potential for chemical warfare before placing in your Picotope.  "Aquarium Corals", a book by Eric Borneman, is an excellent resource you might consider employing.>    
Thanks again Joe

NMA Books/stocking 20L nano-reef    5/16/07
Hi all,
<Alex>
First - I really enjoyed the RI book - when is the sequel due out?
<Indeterminate... JasonC is working on the two fish books/volumes... but don't know at this point... maybe later this year>
Secondly - I'm trying to settle on fish for my upcoming 20L ("L" for long, not liter) nano-reef (with 10 gal refugium).  I would like to have a group of very small fish, and am liking the idea of a group of conspecific gobies.  I understand that this will work with Elacatinus sp -
<Mmm, maybe... really only with very closely related ones... best from the same "batch", tank-raised... see your dealer re ordering from an outfit that produces these if this is the route you're going>
what about Stonogobiops, e.g. yasha or nematodes?
<Can be done... in pairs here>
  Also, for the latter and for shrimp gobies in general, how necessary is the shrimp commensalism to their happiness in captivity?
<Not... though makes for far more interesting behavior, viewing>
Will they thrive without a shrimp if all other parameters are OK?
<Yes>
I am thinking to avoid Gobiodon clown gobies as I would like to grow some SPS frags and they can apparently be hard on such.
<Yes... and each other with crowding...>
Also, I would like to have one small "active" fish to complement the more demersal/passive behavior of the gobies.  My thinking is leaning toward one of the smallest of the Flasher or Fairy wrasses (e.g. P. carpenteri or C. filamentosus), or possibly a six-line,
<Mmm, no... not enough room here>
but am wondering whether this would be too large/active a tankmate for the gobies, and whether a lone male Flasher would look good, or if they only color up/display in the presence of conspecific females?  
<This latter really>
Other possibilities for my "active fish" would be a small Basslet (Gramma brasiliensis?  Or a Swissguard or Candy Basslet?  Blue Assessor?).
<Again... really too small a volume for these>
  Really don't want Nemo (or any other damselfishes), and am cool at best to firefish (would love to have other Dartfishes if I had a larger tank, but I don't).
<Correct>
Thoughts on the above and other suggestions welcome!
Thanks in advance
Alex
<Mmm, have you read here: http://www.wetwebmedia.com/smmarsysstkgfaqs.htm
and the series linked above? Have you seen Scott Michael's "Reef Fishes" pocket guide book? Bob Fenner>

Re: New hobbyist to marine aquariums   - 5/18/07
Thanks for your reply.  We only have a 58 litre tank (15 US gallons) and can only have about 4 fish altogether so need them to get on.
<Mmm, four very easygoing fishes perhaps... the ones you have are not...>
We have had an Anenome appear on the rock and also a spaghetti worm as well as a snail and we have bought a hermit crab.
<...>
We currently only have the two fish an ocellaris clownfish and presumed Dottyback?  We should have asked at the shop about the species but as we are novices and the shop knew this, we thought we were buying compatible fish and with all of the excitement (2 very eager children) didn't write it down - I can't find it in the books either!.
<I'd go back to the shop and ask...>
Looking through the book I have it does show that Dottybacks are compatible with clownfish
<Some species... but not in small volumes...>
and that they can both be mildly aggressive.  I was hoping you may the best next step for us.
<Me?>
Would it be OK for us to introduce another ocellaris clownfish now?
<... no my friend... your system is too small...>
I had read that you needed to buy them together if they were to be pairs, otherwise you shouldn't mix more than one of each species in a tank?  Any help would be of value.
PS: We have tried to photo the blue fish but it won't stay still long enough!
<Do make a trip to the local library... check out and read a recently published book on Marine Aquarium keeping... spend some time reading... You're setting yourself up for failure with the present slipshod approach to the hobby... Bob Fenner>

Re: Compatibility question for new marine setup   - 5/18/07
Thank you so much for the prompt reply, and Mr. Fenner, let me say your book is far and away my favorite of all the books I have read on the subject of marine fishkeeping!  
<Am glad you have benefited from its perusal>
Ok, I will stay away from the clown goby, although I will admit I am a bit sad as everything I have read says they are wonderful fish with great personalities.
<As stated, live on, within SPS colonies... on which they derive nutrition... Not actually/generally easily kept>
  But I would hate for the little guy to be unhappy since we are not planning on having corals, or to be tormented by the bi-color blenny.  "Sigh..."  
<Yes>
But in that case, I would like to add some yellow to our tank, so instead of the bi-color blenny, what about either the midas blenny (I like that he will swim around and not stay hidden all the time) or the Canary Lyretail Blenny?
<A good choice>
Again, the biggest questions being would either be a good choice for a novice aquarist like myself, be compatible with the hex aquarium and other tankmates (the blackcap Basslet, a pair of ocellaris clownfish, and a flame angel)?
<This tank is a bit small for a Loricula... but the others will likely go, be fine... and there are MANY other choices...>
Thank you so much for taking the time to respond.  I can imagine the number of questions you get
<A few dozen a day...>
and how busy you must be, but I greatly appreciate your input and advice.  Nothing I would like more than to prevent any newbie mistakes that could result in harm the life I am so looking forward to keeping.  
Jamie
<Am happy to co-conspire with you... You're doing fine. Bob Fenner>

Nano-Reef Stocking    5/15/07
Hey Crew,
<Hello.>
I have a ten gal. nano with a small yellow clown goby, and four dwarf seahorses.
<Too much and wrong type of livestock for this type of tank.>
If I were to add a chalk Basslet, would I be over crowding the tank?
<Already 'tis my friend.>
Also, does the amount of bio-filtration (macroalgae, live rock etc. .) reduce the needed frequency for water changes?
<Mmm, not in your case, you'll be needing' at least 20% weekly or bi-weekly on this tank.>
I don't really have a problem with water changes, but it just seems a shame to waste more water than I need to. guess I'm in the wrong hobby) :)
<Please see our nano articles on the main site.>
Thanks!

BTA, Entacmaea quadricolor in a Nano Tank – 5/8/07
Hello Crew,
<Hi Matt, Brenda here>  
Throughout this past year I have relied heavily on your FAQ’s to obtain knowledge in proper husbandry.
<Great!  Happy to hear you find it helpful.>
This particular is regarding a new setup with a 24G JBJ Nano Cube. I have used “cured” rock from my 200 gallon reef of over a year, along with water from the same tank to quickly cycle the new Nano Cube.
<Did you transfer any of the sand?  An established sand bed is important.>
My Nano setup is: 150 watt Viper Light, Remora Protein Skimmer, Koralia Powerhead, 35 Lbs Live Rock, JBJ Auto Top off, Milwaukee Ph Monitor and so on. My question is this, with careful weekly water changes and diligent checking of water parameters, is it possible to have several 2-3 rose anemones in this species only tank?
<It is possible, but I don’t recommend it.  Water quality can go down hill fast in smaller tanks.  One anemone can quickly out grow a tank of that size.  Also, a powerhead can be deadly to an anemone.>
Also, what is the proper temperature to maintain such creatures? I am hovering around 77-78 right now.
<79 – 81>
I would appreciate any input as I value your experience highly.
Thanks, Matt
<You’re welcome!  Brenda>

Oceanic 29 Gallon Bio Cube. Euph/(frogspawn) in Nano Reef?  – 05/08/07
Hi crew.
<Hi.>
Before I get to the question I just want to say how helpful the site is.
<Go on……………>
VERY!!!
<Great; thanks!>
Anyways I would just like to know if you think that the Oceanic 29 Bio Cube has lights powerful enough to keep a frogspawn coral healthy and happy?
<Tis’ borderline. Not only the lighting but the size of the aquarium will make it difficult to keep the chemistry stable for this animal. But it is doable.>
It comes with 2 36w pc's.
<I would make sure both are 10,000k bulbs and replace them every 6 to 9 months as PC’s depreciate in lumens at an alarming rate in comparison of other types of lighting.>
If it is not, I heard of this  website called nanocustoms.com where they mod nanosystems. I just want to know what you think of this site,
<Am familiar with it. Have not used it personally, though I know many who have and have been very satisfied. Can’t give you a personal opinion really as I have nothing to base it off of. Having said that modding the original set-up may void the warranty. And I believe, though I am not sure, that nanocustoms gets around this by offering their own warranty. At the least it is something you should look into.>
if you've heard of it and would 4 36w pc's be enough?
<Yes but then there are heating issues to be concerned about.>
Also they have a skimmer on that site that fits into the back of the Bio Cube made by Sapphire which I never heard of, do you know if it is a good quality or not?
<No am not familiar with it either, though any skimmer is better than none….to many nano-‘ers go skimmer-less. Read this to; http://www.wetwebmedia.com/nanoreefsysart.htm .>
Just looking for your input.
<^^ There it is.>
Thank you.

Compatibility for 25 gal tank – 04/30/07
Hi there,
<Howdy>
I have a question regarding compatibility of fish, corals and invertebrate. I started   25 gal saltwater tank with 25 lbs of live rocks , hang on filter and Fission Nano Skimmer. Temperature, PH and salinity are perfect.  Its been running like that for three weeks now . I put Javanese Damsel and couple of Nassarius snails after two weeks of running and started the protein skimmer at the same time. Fish and snails are  doing fine even though the Nitrite level has been  rising by third week. My question is ; what kind of fish , corals and invertebrates should I put to match with the Javanese Damsel after my tank cycles?
<... a wide selection...>
  I saw the list of Fish that would do good in Nano reef but I don't like most of them , except Clownfish.  The kinds of Fish I was thinking about were; Clownfish,  Damsel,  Few different types of  Chromis, Spotted  or  Banggai  Cardinals (or both) ,  Dwarf Angel ,
<Maybe a "dwarf dwarf"... covered on WWM>
Clown or Rainfordi goby (or both).  Also wanted to put some  Zoos ,  Mushroom Corals   and  tiny Starfish  and few different kind of Snails. Please advise which of them from my choice list I can put in there after the time is right without crowding. Also how many fish I can put in the 25 gal reef tank ?
<About three to four cubic inches...>
Can I put two different kinds of Clownfish ?
<No...>
Or two of same kind of Clownfish? How about two different types of Damsel or two of the same Damsel ? Your insight would be highly appreciated.
Sincerely,
VICTOR

Nano Compatibility 4/25/07
Hi Crew,
<Hello>
I have a 10 gallon with a clown goby (3 years),  a spotted cardinal (3 years), a royal Gramma (2 years) and a pair of neon gobies(1 year). <Seems like a lot of fish to me.> When I got the Gramma he was about half the size he is now. I think he would be better off in a larger tank and I would like to replace him with a fire fish.  <I definitely think he would be better off in a bigger tank, but I would not replace him.> And he bullies the cardinal. <Yep, they do that.> Is there any reason to think the firefish and Neons would not get along? <Probably, but in such a small area all bets are off.>  Also what is the life expectancy of the Gramma. <10 to 15 years probably, although few live that long.> I couldn't sell him if he can not be expected to live much longer.  <Most marine fish are very long lived when properly house.>
Thanks

29 gallon cleanup crew  4/25/07 
Good Evening! I have a question regarding a suitable clean up crew for my 29 gallon setup. Everywhere i go seems to have their own package of different animals. I'll explain my setup and if you don't mind, could you tell me what would be an ideal clean up crew. Current inhabitants include 1 ocellaris clown, 1 scooter blenny, 1 rock flower anemone,
<Not a good animal to mix with the other Cnidarian Classes...>
1 green Ricordea, couple of red mushroom polyps, 1 small colony of blue zoos, 3 small giant sun polyps, and 1 sally lightfoot. After further reading, I'm finding out the sally may not be such a good idea... I'll keep a close watch. My sand bed is CaribSea aragonite 1 1/2 inches deep. The only other animals I'm likely to ever put in this tank are some more corallimorphs and the like.
<Again... this mix is a disaster waiting to happen...>
I do have a small hair algae problem. Thank you very much in advance for any info you can provide. I'm grateful that there are people like you guys who help guys like me so much. Have a good evening

Stocking question, small reef, and FYI, re: der. of Yasha haze...  4/24/07
Hello Crew,
<Eric>
Long time reader, first time writer here.  (Actually, I wrote about a week ago and didn't receive a response, so I'm trying again.)
<Good>
I have a 7 gallon (5 gallons of water) tank (30cm x 30cm x 30cm) with a little under 3kg of live rock, a Stonogobiops yasha and an Alpheus randalli.
  Lighting is 40W of compact fluorescent.  All filtration is biological via the live rock, and I have a power head and a hang-on filter with the media removed which combine to circulate the water 25 times per hour.   Ammonia and nitrite are at zero and nitrate is at 5ppm.  SG is 1.024 and pH is steady at 8.3.  Alkalinity is at 4 meq/l.  (All data is from Red Sea tests.)
Can you recommend a second fish that will be comfortable in this size tank?
<Some of the very small, easygoing Pomacentrids, Apogonids, Blennioids, Gobioids... many possibilities>
The aquarium stores I've visited here in Japan have made all sorts of suggestions, but I'm pretty doubtful about all of them.  I'd really like to find a compatible fish to add, preferably one that is a free swimmer, because the tank seems lonely with the goby and shrimp hiding almost all of the time.
Also, FYI, I see lots of different spellings, variations on the common name for Stonogobiops yasha, and I thought you might be interested to know that the fish's common name in Japanese is "yasha haze"  "Haze" is pronounced "hah-zeh" and means goby, so the term "yasha haze goby"@is actually redundant.  "Yasha" is a female demonic warrior deity, and I assume that the goby gets this name from its bright red stripes and spiky dorsal fin.
<Thank you for this>
Thanks in advance for your advice.
Yours,

Re: stocking question and FYI  4/25/07 
Mr. Fenner (or which ever member of the Crew can respond),
<Eric>
Thank you very much for your guidance. Of the genera you mentioned, I am most interested in the Pomacentrids. After a quick check of the area LFS's, I found that the only member of the genus immediately available is Pomacentrus alleni.
<Is a very good choice... as might be some of the small/er Chrysiptera... Talbot's, C. taupou...>
My wife and I both think the fish is very attractive and would like to move forward, but I thought it best to check back with you once more to confirm that this is a suitable choice. The FAQs on WWM regarding this species seem to indicate that this is a less aggressive member of the genus, but also that it often does best when kept alone.
<Yes>
In your opinion, will it and my yasha goby get along? I also found references on the Web stating that the minimum tank requirement for Pomacentrus alleni is 30 gallons, although I also found examples of people keeping them successfully in nano tanks. Should I be concerned about this?
<I do give you very good odds here>
I apologize for taking up so much of your time. Once again, many thanks for providing such a useful resource!
Regards,
Eric Anderson

10 Gallon Marine Nano, Much Reading Needed  – 04/16/07
Hello Mr. Fenner,
<Sorry to disappoint...this is Adam J filling in for Bob F.>
I have had fish for a while with success and I want to start a 10 gallon fish only tank.
<Does not leave you with very many options, livestock wise in a marine tank.>
I was thinking of starting with just a regular 10 gallon setup, with a Skilter 400, and a powerhead for filtration.
<Mmm...Skilters are convenient but unfortunately not very effective in most circumstances, I would opt. for either a hang on refugium or protein skimmer...maybe both if you can fit them.>
I'm thinking of either having 1) one Dwarf Zebra Lionfish,
<Far too large for this aquarium.>
or 2) One Pygmy Angelfish.
<Also too large...>
I was just going to use lava rock or Texas Holey rock for hiding/sleeping places.  Thanks for your time/suggestions.
<See this article regarding nano marine aquaria:
http://www.wetwebmedia.com/nanoreefsysart.htm .
Read this and more....do as much research as possible, nano tanks are not easy not for the faint of heart, they are a roller coaster as far as maintenance and stability go.> <<Well-stated. RMF>>
Thanks

BTA in Nano Tank?   4/11/07
Hello crew
<Hi.>
Tyler Kohring  today
<Adam Jackson on this end.>
I have a 24 gal. reef tank which has had is ups and downs.
<Nanos tend to do that...fickle creatures they are.>
Now it is finally back to normal.
<Good.>
Anyway I  wanted clownfish for a while, but I didn't like the normal perculas so I decided to get two black Australian perculas. * very cool fish *
<Especially the tank-reared versions.>
I have not had them long but they are doing good, one is slightly larger.
<Normal.>
they seem to have paired up and I want to give them a anemone.
I had a bubble tip anemone on mind. Do you think this is a good choice if not can you suggest one?
<Well first I think it is important to mention that clowns in captivity do not need anemones in any sort of way to be happy. In fact most people who breed the animals on a large scale do not use anemones...in fact I don't know one commercial breeder who uses them. If you do get an anemone it is strictly for your enjoyment...the clowns don't care.  Anemones is general are not easy to maintain in captive aquaria, most don't live a year in captivity. Out of all of the choices, E. quadricolor, the BTA is probably the best choice, but that's not to say they are easy by any means.  If you do get one, your best bet is to go for a captive reared specimen.  I'll end by saying I do not personally recommend it. I do not like to see anemones placed in nano aquaria, as you've mentioned they have their ups and downs and anemones appreciate very stable environments with low nutrient levels. Be sure to so all your research and read the articles/FAQ's placed on WWM.>
Tank is four months old tank mates: bicolor blenny, Australian perculas, fire fish, Rainford goby, and six line wrasse.
<Tank is a bit overstocked for my liking...being a nano and all.>
Thanks for the help,
<Anytime.>

Ich on corals? Cnid. allelopathy, esp. dangerous in smaller vol.s  3/28/07
Hi guys!  I'm hoping you can help me out of what I'm afraid might be my 1st experience with Ich (or marine velvet). I have a 24g Nano with MH lights, temp=80, spg 1.025, ph=8.3-8.4 (depending on am or pm measure), calcium=450, nitrites, nitrates and am=0.  I do 3g H2O changes weekly.  We have 2 true percs, a royal Gramma, 2 peppermint shrimp, assorted snails and hermit crabs.  Corals include Blasto, assorted mushrooms, zoas, sun coral (my favorite), toadstool and Palys.
<Yikes... trouble with all these disparate Cnidarians down the road... with growth... do settle on not adding any more species... and DO be diligent re maintenance>
I noticed white spots on our palys 4 days ago, and they have gotten worse.  I removed and gave to a friend to put in his hospital tank (I am getting one tomorrow!).
<Good moves!>
  Now I noticed that the Gramma is looking beat up. and scratching itself on the live rock. He's not breathing heavy, though. I think I see 2 pinhead white spots on the fin of 1 of the percs. I plan to take all 3 fish and put in hospital tank as soon as I have it set up, but I'm wondering if the corals are at risk of this parasite, since it seemed to start on the palys.
<Mmm, not likely a parasite... of any of them... But very likely a matter of the fishes being exposed to types of chemical warfare twixt the stinging-celled life... "Caught in the cross-fire" so to speak">
I have had them for 1 mo already.  I just don't want to treat the fish, and wind up with all the corals getting this white stuff too!  Please advise!  Thank you!!  
-Debbie
<Please read here: http://wetwebmedia.com/cnidcompfaqs.htm
And the linked files above... Perhaps my write-up on Tom Walsh's small systems from years back... The "Garden Mix" of Zoanthids, Scleractinians et al. you list is possible, though not really practical in small volumes... these sessile animals species have varying, but highly effective strategies for "saving space", hogging light, gathering food exclusively to themselves... These potent stinging, poisoning, over-growing mechanisms easily play havoc in small captive systems... As you are experiencing. There are a few strategies for limiting the morbidity and mortality here... Read on. Bob Fenner>

Re: Ich on corals? Bambi vs. Godzilla short parody/explanation   3/29/07
As always, thank you for the prompt reply!  You guys are wonderful!! Just so I understand correctly what "next steps" to take, if the likely culprit is chemical warfare rather than a parasite, would the best course of action be to relocate some of the corals into a separate tank, rather than placing the 3 fish in a hospital tank and treating with copper, etc.?
<... please read where you were referred to>
I do think the hospital tank approach may be premature,
<Agreed>
as none of the fish appear to have breathing difficulty or white spots -- only the Gramma is scratching on the rocks very frequently, and seems unhappy.  If a larger and separate tank is what you suggest for separating the corals, which of the following corals would get along best together? (red & green mushrooms, green and blue hairy mushrooms, button polyp frag, zoas, xenia, toadstool leather, sun coral). Please note that I have looked for a Compatability chart for specific corals,
<Good point... As far as I'm aware there is none that is comprehensive... too much of "this goes with that, but not with this other" factual matter to graphically present>
and I just seem to get general information about keeping 6-10" spacing, etc.
<Is a good idea... as is starting with small specimens, colonies, the less noxious/stinging first... Additionally, frequent, partial water changes, use of chemical filtrants... diligence in cleaning/operation of your skimmer...>
The reason I am so confused is that many reef tanks I've seen appear to have many different corals living together in close proximity.
<All a matter of balance, time going by, and all potential trouble/time bombs... as in the wild, what appears to many folks, or as so pastorally "painted" as calm, serene cohabitation is in actuality an extremely aggressive world of chemical and physical warfare, kept in check (but not static by any measure) by dilution of water currents, predation, meteorological events...>
I love the look of a reef "garden" with lots of colors, but I'm not sure how to avoid the chemical warfare issue. :-(  I greatly appreciate any advise you may have!  
Thanks,

29 gallon saltwater... stocking  3/28/07
Hello!
<Katharine>
I've had my 29 gallon tank set up for saltwater for about a month now.  I've got 4 lbs. of live rock growing some coralline algae in there.  The filtration consists of a 30 gallon hang off the back bio wheel filter, with a sponge, some "bio balls" and a "Purigen" bag.  I've just added two Green Chromis, and I want to add an Ocellaris Clown pair soon.
<Mmm... these should get along... but the Chromis are more social... like to live in larger settings, in greater numbers>
I want to set up a refugium, but I'm having problems fitting anything large enough to work under my aquarium.  I know there are hang off the back refugiums, but I'd rather have it under the tank.  My question is, what else can I put in this small of a tank safely?  Thank you!

<Heeeeee! The list is indeed long... likely some of the smaller gobies, blennies would be good bets... Please see WWM re. Particularly: http://wetwebmedia.com/smmarsysstkgfaqs.htm
