TLK, i feed them everything really. feeders by the 50's. shrimp by the pounds. pellets by the handfuls. i've never tried full fish that big but im sure it would. ii've fed large mice a few times which im sure some disagree with but i don't really care. i clean my tanks enough to not care about the dirtyness it creates. large lizards when i catch them. hotdogs occassionally. they'll eat anything that hits the surface
