Ecologia
marino; acqua dolce; salmastro benthopelagico; amfidromo (Ref. 138274); distribuzione batimetrica 0 - 5 m (Ref. 86942). Tropical; 25°C - ? (Ref. 2059); 30°N - 32°S, 25°E - 176°E
Africa to Oceania: Red Sea and East Africa, south to Transkei in South Africa, and most inland freshwater bodies over the Indian Ocean and western Pacific (Ref. 4343, 52193). Common in coastal and estuarine waters from austral Africa and Madagascar to India and south of China.

Adults are found mainly in freshwater and estuaries, but also enter the sea (Ref. 4833). They also occur in canals, ditches and ponds (Ref.12693), in clear to turbid streams with rock, gravel or sand bottoms (Ref. 2847). Encountered in medium to large-sized rivers of the lower Mekong (Ref. 12975). They feed on small insects, crustaceans and small fish. Grow to a much larger size in brackish water than in fresh water. Marketed fresh (Ref. 12693). Cannibalism is relatively common for this species (Ref. 48660).

Spawning occurs in freshwater afterwhich eggs and larvae are washed down by the river current into the sea (Ref. 110258).
