Hi guys I need some help with my stocking. I have a 6x18x20 uniquarium. Basically I have 82 gallons for the fish and another 30 gallon for the sump in the back of the aquarium. The real dimensions for the fish will actually be is 6x13x20. My stock as of now is a 5" Jack Dempsey, 5" green terror, 3" chocolate cichlid,3" firemouth and 2 3" rapheal catfish. I would like to put 1 more Jack Dempsey, but I feel I will be pushing it. Tell me what you guys think. Thanks in advance Vince
