|Population:||There is no information available. In the Sesan basin, it is impacted by dams.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is found in rivers, streams, canals and ditches (Rainboth 1996); it occurs in medium-sized rivers, especially tributaries, and enters flooded fields (Taki 1978). It is largely herbivorous, consuming aquatic macrophytes and submerged land plants, as well as filamentous algae and occasionally insects (Rainboth 1996). It also feeds on small fishes, worms and crustaceans.|
It requires flowing water and would not be expected in reservoirs, but is found in still water in Singapore where it has been introduced.
|Movement patterns:||Full Migrant|
|Use and Trade:||This species is used in subsistence and local fisheries, aquaculture (for commercial production and the aquarium trade), and occasionally as bait in fisheries. It is usually marketed fresh.|
|Major Threat(s):||This species is not thought to have threats across its range. Populations have declined as a result of dams in parts of its range.|
|Conservation Actions:||None required.|
