I have a 26" really pink colored jar, that I haven't seen eat in a month or so. I feed the fish in his tank sinking pellets and massivor pellets. I have another 12" jar and a 14" black aro. They both eat pellets. The bigger jar is really a bully. I've just about decided he eats what the others eat or not. He'll either eat or starve. Idias are welcome. By the way he used to like frozen blood worms, but not what I would thin enough to keep him alive. He seems healthy.
