A plankton feeder occurring mostly in swamps or flooded grounds of coastal zones, either in turbid or clear stagnant water (Ref. 35237). Possesses very long and very fine branchial archs which allow it to filter microorganism-rich waters of the flooded savannas and swamps which are its preferred habitats (Ref. 27188). Males are larger than females, attaining maturity between 17 and 22 cm. Reproduction takes place during the rainy season (Ref. 35237).
