Habitat and Ecology [top]
Habitat and Ecology: Inhabits swift, clear streams with sandy or gravelly bottom; also found in large rivers; burrows into the bottom and enters flooded fields (Talwar and Jhingran 1991). Found in the basin-wide mainstream of the lower Mekong. The general colour and marking serve to afford the fish concealment in clear, shallow, sandy streams (Pantalu 1986).
Acantopsis species are near-exclusive inhabitants of flowing river channels with substrates of sand, fine gravel or mud but are known to migrate into temporarily flooded zones during the wet months of the year (Seriously Fish 2011).
Systems: Freshwater
Movement patterns: Full Migrant

Use and Trade: Found in fisheries, and of some interest as an aquarium fish.
