After selling all the fish in my 55 gallon, except for me bn pleco, a week later (today) i introduced 6 new cichlids into the tank. The strange thing is, my pleco is chasing them! I have never seen this before and thought plecos really kept to themselves! I'm kinda worried, cuz these are quite expensive cichlids and i don't want the pleco to hurt them! Anybody else have pleco aggression with other fish? Anybody know whats goin on with mine?
