Habitat and Ecology [top]

Habitat and Ecology:This species is found in flowing streams and rivers, typically murky waters containing a lot of sediment. They are seasonal spawners which lay their eggs at the beginning of the rainy season, then the fry then migrate to flooded areas to feed and grow.

The species' dominant presence at the Khone falls is during dry season, it exhibits a small peak in the beginning of the rainy season. (Baran et al. 2005).
Movement patterns:Full Migrant

Use and Trade [top]

Use and Trade: This species is found in the ornamental fish trade, and in fisheries.

Threats [top]

Major Threat(s): No information is available on threats. Its status as a food fish may render it vulnerable to overexploitation, but this awaits verification.

Conservation Actions [top]

Conservation Actions: Further research into population sizes and trends, as well as the effects of fisheries on it, is needed.
