I'm new here and I have a problem. I have a 60 gallon tank with an eclipse catfish that I've been having for 3 years, and two kissing kish that I've been having for 4 weeks. The kissing fish haven't eaten fish food since I gotten them and my catfish only eats when no one is around. I don't know what to do for the kissing fish they go around pecking everything but they're getting skinny.
