I have a black Wolf that I've had for a few months, and he never had a problem eating (in fact he ate 2 Jack Dempsey, green terror, and a fire mouth). Since I got tired of him eating my cichlids I move him to a larger tank, and he has stopped eating. He is still king of the tank, and is still active he just won't eat( I've tried feeders, beefheart, and pellets). I'm just wondering is this normal? Do they go on hunger strikes like this? Or should I be looking for something else?
