I have a 75 gallon reef tank that currently has only a fire fish. Im considering the next move on the tank, and I'm looking for a fish that is small 2-3 inches adult, active swimmer, and peaceful. Here's what I'm stuck on, I'd like there to be 4 or 5 of them. Many fish seem to become aggressive to same species. I've read that blue/green chromis would be good but tend to use aggression to establish hierarchy and you end up with 1 or two at the most. Any other suggestions?
