Ok, I've had it with this guy, if my LFS will take him,,he's going on Monday. He is terrorizing my whole tank. I have re-arranged my tank several times over the past few weeks but to no avail. I know that over crowding also curbs aggression sometimes but right now I only have one filter on the tank so I don't want to overload it. And yes, I read up on this fish b4 I bought it but guess I under estimated the aggression. This guy is gone unless someone has some stellar advice. Not looking for criticism, just doing some b****ing!
