I don't have any first hand experience with either catfish, but am looking for an active group of readily available fish for a SA community. The tank is 210 gallons 7x2x2 and will house 4 green severums, 2 chocolates, 6 festivum, 6 silver dollars and possibly the catfish shoal. Some of the cichlids may be split off over time as they grow or become quarrelsome, currently all the fish are approximately 2". Other suggestions and any thoughts are appreciated.
