I have a pair of clowns, lawnmower blenny, mandarin, Cleaner shrimp, Emerald crab, anemone crab and a harliquen shrimp.
So far I havnt had any real problems with the acro yet. Except for teh 2 that just died for no reason. that in itself could make them kinda frustrating. The other 6 colonies of it are doing great.
They just needs lots of light and have good flow.
