This fish is only known from subterranean streams in caves in Kham Muan Province, Lao PDR. Given the single location, the nature of the hydrological system, and the likely limited extent of occurrence, the species is assessed as Vulnerable (D2). Current and potential threats are tourism development and degradation of the surrounding watershed and water quality.

Habitat and Ecology [top]

Habitat and Ecology:A troglobitic fish, this species is restricted to subterranean streams some distance from the entrance (over 100 m). Its diet is possibly organic detritus from bat guano and microorganism. Its growth rate and life cycle still unknown.

Use and Trade [top]

Use and Trade: Occasionally harvested for the aquarium trade by a Thai dealer who hires local people to collect the species (2000-2003), but recently inactive.

Threats [top]

Major Threat(s): Declining water flows as a result of deforestation may threaten the hydrographic system in the subterranean stream, as well as contamination by agrochemical use within the watershed. Most troglobitic fish are very sensitive to water quality and hydrographic conditions.

Overfishing may threaten this species, if not controlled or managed.

Conservation Actions [top]

Conservation Actions: Monitoring of populations and threats is required, and research into the species distribution and population status.
