My pacus get pellets, krill, market shrimp, beef heart, bugs ( crickets, earthworms, mealworms), broccoli, peppers, baby carrots, and sometimes fingers. It is a lot of fun to watch them eat the carrots. You can hear them crunching them from across the room!
Very nice I cant wait till mine is that large, but then again I sort of hope he slacks off growing(not likely) for another year until I move out of my parents house. If not I guess hes getting a cattle trough
