This is a wide ranging species that can be locally abundant. It is occasionally traded in aquarium shops, but given its wide range, harvesting for trade is not considered a major threat. It is listed as Least Concern.

Habitat and Ecology [top]

Habitat and Ecology:This species inhabits rocky and coral reefs and can occur singly or in pairs. The diet is diverse, consisting of polychaete worms, coral polyps, crustaceans and mollusc eggs. Animals are monogamous (Whiteman and Côté 2004), forming pairs during breeding (Breder and Rosen 1966). Adults may form plankton-feeding aggregations of up to 20 individuals, and occasionally clean other reef fishes which join the group, such as grunts, parrotfishes and surgeon fishes (Sazima and Sazima 2001).

Use and Trade [top]

Use and Trade: The species is commonly sold in pet shops as an aquarium fish (Allen 1980, Carpenter 2002), but is not harvested for food (Carpenter 2002). During a five year period, 3,096 individuals were traded in Brazil (Monteiro-Neto et al. 2003).

Threats [top]

Major Threat(s): No apparent major threats.

Conservation Actions [top]

Conservation Actions: In view of the species' wide range, populations are present within several marine protected areas.
