Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This little-known species is associated with steep outer rocky reef drop-offs and caves, especially where vertical walls are covered with algae (G.R. Allen pers. comm. 2006, Endoh 2007).
Systems: Marine

Use and Trade [top]

Use and Trade: This species is rarely collected for the aquarium trade due to the limited distribution and deep dwelling habits (G.R. Allen pers. comm. 2006, Endoh 2007, R. Pyle pers. comm. 2009). It commands a high price when available.

Threats [top]

Major Threat(s):

While it has a limited distribution, there is no substantial habitat loss, it is rarely collected for the marine aquarium fish trade, and there appear to be no major threats to this species.

Conservation Actions [top]

Conservation Actions:

There appear to be no species-specific conservation measures in place. It is not known whether this species occurs in any marine protected areas, although it is assumed that populations are present within the Aldabra World Heritage Site.
