Species Profiles
Firemouth Cichlid
Thorichthys meeki
beginnersemi-aggressive30+ gal
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.
