Thanks Manny. Yeah that were lot of rocks I took out, thanks god all of corals and fishes made it, they do look stressed for awhile I guess the tank went through a half-cycle. I have been dosing bacteria and carbon heavily till today, I am starting to reducing to regular dosage.
Yeah these are blue eye cardinals, they are pretty cool (even not very colorful), keep in tight group and maintain the hierarchy most of time.
Sometimes I am thinking to only keep a groups of cardinal and a group of small anthias only, no other fishes , that will make the tank looks bigger, haha. But it is hard to resist those bigger fishes like tangs or reef-safe angels... they are so pretty and so much personality.
