I am currently building a plywood tank. What can I add to it besides my larger Midas cichlid? I have a jaguar cichlid, three tinfoil barbs, two walking catfish, and two iridescent sharks in my growout tank. I was considering adding all of these fish to the new tank, along with the Midas and the jaguar cichlid, while placing the iridescent sharks in the pond. Alternatively, I could add only the tinfoil barbs and the walking catfish to the plywood tank and put the iridescent sharks in the pond. How should I divide the fish to maintain a balanced load on both my 500-gallon pond and my larger tank without any problems?
