Distinctively stunning cichlid, very popular with aquarists which is a bit of a surprise because of its relatively strong territorial instincts. Making it somewhat aggressive towards other aquarium inmates. A well matched pair is a joy to behold. The female has orange scales on her lower body and dorsal fins and the male is larger, less colorful, has a steeper forehead and longer fins. As it ages, the male will acquire a fatty lump on the forehead.
