Species Profiles
Jack Dempsey Cichlid
Rocio octofasciata
Named after the legendary boxer, Jack Dempsey cichlids are large, territorial Central American cichlids with iridescent blue-green spangles across their dark body. They are aggressive, intelligent, and interactive — many owners report them coming to the glass to greet them. The electric blue Jack Dempsey variant is significantly less aggressive and more colorful.

Thorichthys meeki
Firemouth cichlids are one of the most beginner-friendly Central American cichlids. Named for their striking red/orange coloration on the throat and belly, they are less aggressive than most cichlids of their size. When threatened, they flare their gill covers to display their bright red throat — a bluffing display that is far more bark than bite.
