I have aquired a full sized chocolate catfish, i'm not sure what i should be feeding it. I already use shrimp pellets, spirulina discs, discus tucker and bloodworms for various other fish in the tank, will this be enough or does it need something else. There was a gimpy neon and a guppy i didn't like in the tank when i put it in but they have gone missing. Am i right in suspecting the choc catfish? Its the only one with a big enough mouth
