Asia: Mekong and Chao Phraya basins, Malay Peninsula, Indochina, Philippines and Indonesia. Record from Fiji needs confirmation.
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.
