Hi all I’ve just recently bought a 12” -14” inch walking catfish from a friend who just couldn’t find time to keep anymore. Recently moved his tank and changed his features and he’s loving it. Only struggle I’m having at the moment is he’s only interested in bloodworm blocks and I don’t know what else to feed him. Concerned to if I’m not feeding enough or over feeding but don’t want to contaminate the water with waste food he’s not supposed to have or wants. Any help with what people have fed there’s before or know is really appreciated! No luck searching online
