A lot of places say these are peaceful fish. However, I have found some places that say they are semi-aggressive. I have been considering getting one for a while now, but I don't like dealing with aggressive fish. Basically, I'm looking for a peaceful fish that won't bully any fish in the tank whether it be the fish already in the tank or the ones I put in after it (and it must be completely reef safe). Any ideas if this fish would be a good addition or would I be better off with something else? Thanks!
