All good points, thanks fellow MonsterFishkeepers. Yes, it is correct that there is no dorsal fin extension even though the fish is adult size already. There is good coloration on the body and a lot of orange in the tail fin if it is a female. There is a small hump on the head, but I'm not sure if it's enough of a hump to be a male, or if it is a small female hump. Very confusing. I had wanted to get a male and thought it was one based on its size and coloration, but now I'm not sure based on the lack of dorsal fin extension. Also...it's not very aggressive.
