See profile for complete details of my setup, but I've got a 20 gallon tank with skimmer, GFO & carbon reactor, and 20 lbs. of live rock. I also plan on using live sand (whatever amount is recommended by you fine folks).
I'm letting my wife and kids pick the fish, and I'll be picking the coral when the time comes.
They've decided on a pair of very small (an inch or so) LFS tank-bred, tank-raised Ocellaris clownfish.
this is marginally fine; keep in mind that once they are sexually mature, they will want to control about 25 gallons of tank space
First of all, I'd like to ask if you all think that is OK. I think it is, but advice never hurts.
Also, in the future I'd like to add a clean-up crew that includes some hermits, stails, and at least 1 emerald crab. Any recommendations regarding clean-up crew compliment are welcome. I would not do snails and hermits as the hermits will kill snails
Finally, I've several ideas for fish, but I don't know how many to get. When I did freshwater tanks as a kid, we used a general thumbrule of 1 inch of fish per gallon of water. That does not apply to salt water fish.
I don't think this applies to a reef tank. That being said, I'd like to add creatures from the following list: blenny and/or goby-shrimp pair, azure damselfish, and/or some blue-green chromis.
In your sized tank, a goby/shrimp pair would be marginally ok. However the others would not once the clownfish mature
If there is a thumbrule for a reef tank like the one above, please advise. Also, let me know which/how many fish would be OK to add to my tank. impossible to answer for any tank as it depends on behavior, bioload, and ecological niche
If it matters, I'll be adding as many corals as possible, and I'll be adding kalkwasser to my ATO reservoir (a 5.5 gallon cheap tank).
Thanks in advance for all the help/advice!
