Facultative air-breathing in the genus (Ref. 126274); Found in freshwater streams and ponds and brackish estuaries. Usually over mud and rock bottoms, sometimes among weeds (Ref. 44894). Feeds mainly on insects, crustaceans and algae. Spawns during spring in the upper reaches of estuaries (in less than 30% salinity), where aquatic vegetation is plentiful (Ref. 44894).
