I have a 55gal set up that I'm looking to add a bottom feeder into. I would love to get a catfish but don't know if I would be able to introduce it into my tank. I currently have a yellow lab, 2 electric blue Hap. A jack Dempsey, one cichlid I can't identify, and a goldflake Moray eel. I had a Pleco but he continually would swim into the lid and his head wound got infected so unfortunately I lost him. My fish all get along at this point. The yellow lab supriisingly is head of the tank and actually beats up the others when she gets in a mood. But (knock on wood) I have never had a problem with any aggression. Any ideas on adding a catfish to my tank?
