Ive had a peacock bass for about 3 months now and he only has eaten live minnows and goldfish. All of the sudden he has not been eating. His tank mate (Clown Knife Fish) is still eating like a champ but my peacock is not eating anymore. He shows some intrest when his food gets near, but he wont eat it. He will kinda just mouth it away from him instead. I did a water change and he still wont eat PLEASE HELP!!
