Hey fishy folks, I’ve had a red pike for a couple on months now. Love him. Amazing fish. He’s always been a bit of a git to the other fish but always left my ray alone. Now he has started to nip her tail. As I really want to keep him, is there any way to stop him doing this. I understand they have a reputation, but could I add other aggressive fish in to keep him occupied? Couple of Oscar’s maybe. He is the tank boss and ideally needs knocking down a peg or two.
