Description

The Argentine humphead is a cichlid from fresh water of the Parana-Paraguay basin in southern South America. The species grows to about 12 cm and has a deep, greyish body with glittering spots; adult males develop a conspicuous fatty hump on the forehead. As a bottom-dweller it sifts mouthfuls of sand, filtering out small invertebrates and detritus. It is a mouthbrooder. The fish is harmless to humans and is known from the aquarium trade.
