Found in coastal areas and mangrove-lined lagoons, also enters freshwater. Carnivorous. Feeds mainly on small fishes, especially clupeoids. Occurs at temperatures ranging from 26 to 29°C (Ref. 4959). Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205). Sold fresh in markets.
