What's wrong with oscellaris? My lfs had a pair of maroon clowns in on Friday, some knowledgable r2r members talked me out of that though. I may get a pair of Picasso percs one day. Your corals should be fine, it's the anemone I was unsure of. Also, hopefully this is not the case, but I expect the chromis will reduce their numbers down to 1 eventually. They do bigger in groups of 5 or more, sure, but in that size tank I think they'll think they have to compete too much. Hopefully I'm wrong. I had 2 in my 10 gallon, they got along great for about a month. Then one morning one was finless and gone. [emoji17]
What kind of light are you using?
