Found in lagoons and estuaries, entering freshwater and paddy fields (Ref. 7245, 30573). Common in tidal reaches and nearby upstream areas of coastal rivers (Ref. 12693). Lives in holes in the river bottom and bank and actively forages for small fishes at night (Ref. 12693). Reported to spawn in rice-paddies during the rainy season (Ref. 12693). Caught in bag nets and similar gear. Marketed fresh.
