Notes: The name "Green Terror cichlid" used to refer to Andinoacara stalsbergi which has a white lining on the edges of the fins instead of the orange one found on rivulatus. These cichlids are best put in tanks with a darker substrate to make their blue color "glow". These fish are also very, very, very slow growers.
