We have wayyyy too many fish but they seem to do very well. 5 Tangs (Sailfin, Naso, Hippo, Yellow and Kole), a couple of clowns, 3 blennies, 5 Damsels, and a dwarf angel. 2 Starfish and lots of snails and crabs, The Tangs get along great. The problem lies with the %*&-$# Damsels and the Angel. They are idiots and I'm thinking getting rid of them and putting something else in. Although, it took us about 6 months and a lot of costly mistakes to find the right fish/coral/liverock combination.
