Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-10-09
Assessor(s): Pyle, R. & Myers, R.
Reviewer(s): Elfes, C., Polidoro, B., Livingstone, S. & Carpenter, K.E.

Listed as Least Concern in view of its wide distribution, large overall population, collection for the aquarium fish trade is not globally impacting the population, and there are no other potential major threats.

Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is commonly found in rich coral areas and sometimes over rubble, most usually on sheltered outer reefs, but also in lagoons and passages (G.R. Allen pers. comm. 2006). Feeds on algae; forms harems of three to seven individuals (Pyle 2001).

Use and Trade [top]

Use and Trade: This species is occasionally exported through the aquarium trade (Pyle 2001).

Threats [top]

Major Threat(s):

There appear to be no major threats to this species. Although it is occasionally collected for the aquarium trade, harvest levels are not considered to be impacting the global population. There is no substantial habitat loss in the range of this species.

Conservation Actions [top]

Conservation Actions:

There appear to be no species-specific conservation measures in place. In view of the species extensive distribution it is presumably present in some protected areas.
