Environment: milieu / climate zone / depth range / distribution range
Freshwater; brackish; demersal; pH range: 6.5 - 7.5; dH range: 10 - 15; potamodromous (Ref. 51243); depth range 10 - ? m. Tropical; 22°C - 28°C (Ref. 13371); 23°N - 9°S

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 65.0 cm SL male/unsexed; (Ref. 43281); common length : 30.0 cm TL male/unsexed; (Ref. 12693)
Facultative air-breathing (Ref. 126274); Found in rivers, swamps, reservoirs and canals. Enters flooded forest (Ref. 9497). Feeds on small fishes, shrimps, aquatic insects, mollusks and crabs (Ref. 6459). Considered a delicacy over much of eastern Asia. Exported fishes command a high price (Ref. 12693). Maybe the largest species of the goby-like fishes.
