Is it normal for them to spend most of their time just laying on the bottom of the tank? I have 2 and they both act the same. They are both under 5 inches. One is 3.5 the other is about 4.5. What should I be feeding them? And how do I get them to eat? I've been feeding them black worms because that's what I feed my peacock bass. I've tried shrimp pellets blood worms and frozen beef heart. The beef heart I've only seen them eat a couple of times. They don't go after it like they do the black worms. The rest of the stuff they don't even pay attention to. It can literally be on their nose and they won't even move. Help a new catfish owner. These are the first bottom feeders I've ever had aside from pecos.
