Good to know!! I am really sorry to here that though... That must have been awful!!! They have so far never showed any aggression to him yet, but of course that does not mean one day they wont. I am in the middle of getting a larger tank that I am moving my monsters too. I am going to keep my smaller cichlids in the tank they are now like my Firemouth and Convict and I will keep the Cory in with them.
