I have a problem of a overstock of convicts cichlids. I have a 640 gallon Cichlid pond. Started with 6 Oscars, 1 Jaguar Cichlid, 2 Jack Dempseys, 1 Red Devil, and 6 Convicts. The purpose of getting the convicts was for the Oscars to eat the convict babies. That never happened. Now I have over 100 convicts. I am thinking of getting a Red Tail Catfish for awhile to clean them out. Then give it away when done. Would that idea work?
