There is no question in my mind that it is a Dovii, anyone who has owned one above 10 inches knows what I'm talking about. I have owned 12 inch Oscars, Chocalate cichlids,large severums, Manguense, 15" Peacock bass, pikes etc etc none of them compare to the intelligence and interaction of a large male dovii. Oscars are probably second but a very distant second.
