Species Profiles
Firemouth Cichlid
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.

Metynnis hypsauchen
Silver dollars are large, disc-shaped, peaceful schooling fish related to piranhas — but entirely herbivorous. Their shimmering silver body catches light beautifully in motion. They are excellent dither fish for large cichlid tanks because their calm, open-water swimming behavior helps reduce cichlid aggression. Warning: they will eat every live plant in your tank.
