Firemouth Cichlid

Thorichthys meeki

Firemouth cichlids are famous for their dramatic territorial displays, flaring fiery red opercular membranes and projecting throat membranes to appear twice their actual size. Monogamous pairs clear smooth stones or sunken wood to deposit hundreds of adhesive eggs, fiercely defending their brood against intruding fish. When foraging, these bottom-dwellers scoop up mouthfuls of sandy substrate, filtering out tiny invertebrates before expelling the inedible sediment through their gills.
