I've had my RES ( Ike and Tina Turtle) for a few years now but in the last few weeks Ike has been constantly trying to bite Tina. Sometimes he will suceed and grab her by the back of the neck. I've tried separating them, but when I reintroduce Ike to the tank he attacks Tina again. Is there anything I can try short of getting a separate setup for Ike or giving him up?
thanks
