Research into population trends, habitat trends, and impacts of known threats.
Location Information
The species was described by Freyhof (2003) from River Thu Bong basin in Central Viet Nam (Quang Nam Da Nang Province), and presently it is known from this area only.
Population Information
In the last ten years (2000-2010), a strong decline in the abundance of the species has been observed (J. Freyhof unpub. data).
Threats
Major threats to this species are habitat degradation through massive water pollution and siltation caused by gold mining activities and deforestation practices, overfishing and dam construction. Further research on the impact of collection for the aquarium trade is required as it may be collected in high quantities.
