Hi, I have a 80 gallon tank. So far I have a fire goby, 2 cleaner shrimp, and 4 snails. The next one on my list is a blue green chromis. I was just a little concerned about their behavior. Even though this is a pretty peaceful fish, it is still in the damsel family. Will this fish be aggressive to other new added fish? Also I am just getting one, because if they are in small schoold, they will pick on the weakest one, and end up with just one. I have seen some aquariums with a single green chromis, and they seem to do pretty well.
