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).


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.
