This species has a very wide distribution in the tropical waters of the Indian and Pacific Oceans. Although there is no evidence for any population declines, it is taken in the marine aquarium fish trade, and occasionally also for food. It is, however, well protected in Marine Protected Areas within its area of distribution. This species is therefore listed as Least Concern.

Population [top]

Population:This is apparently a relatively common species throughout most of its broad range. There is no other population information available for this species.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species occurs in insular and coastal waters primarily around coral reefs, and particularly in clear lagoon and seaward reef areas over mixed living coral, coral rubble and sand habitats, from the lower surge zone down to 30 m (Myers 1991, Lieske and Myers 1994).

It is carnivorous, feeding mainly on benthic macro-invertebrates (Masuda and Allen 1993, Lieske and Myers 1994). It shows some sexual colour dimorphism. It is not known whether this species is a protogynous hermaphrodite like most other members of the genus.

Use and Trade [top]

Use and Trade: This species is occasionally captured live and traded as an aquarium display species, and in some areas it is also taken for food in local subsistence/artisanal fisheries.

Threats [top]

Major Threat(s): There are no known major threats to this species, though specimens are occasionally captured live for the marine aquarium fish trade, and others are occassionally sold in local fish markets for food.

Conservation Actions [top]

Conservation Actions: There are no specific conservation measures in place for this species, however its distribution overlaps several marine reserves in parts of its range.
