I know that Leopomis Cyanellus is NOT a chiclid, i am planning to house it in my 55 gallon cichlid tank once it grows to a suitable size. There is no sunfish thread, so i am posting it here. Anyways, right now it is only 1 1/2 inches long and is currently housed in a 3 gallon planted tank. Green sunfish i heard attain length of 5-7 inches in aquarium, and up to 12 inches in the wild. My sister actually caught this one at Lake Pleasant when it was only 3/4 inches long, and since then it has grown lots of personality. I give it a mixed diet of frozen brine shrimp, omega one fish flakes, live scuds, and floating chiclid pellets. From my experience so far it has proven a very easy fish to care for, but i wonder if that will change when it grows larger.
