There have been declines documented in some areas due to coral bleaching events, however these are not believed to have substantially affected the global population. In addition, this species has a wide distribution, large population and no apparent major threats other than coral loss. It is therefore listed as Least Concern.
|Range Description:||This species occurs throughout the Indo-west Pacific, from the Red Sea through the Indian Ocean to Samoa. Northern limit of range is southern Japan, to south New South Wales and Lord Howe Island (G.R. Allen pers. comm. 2006). Found at depths ranging from 1-25 m.
Range size ~60.3 million km2, from values estimated by Jones et al. (2002) based on projection of distribution maps from Allen et al. (1998).

|Population:||This is a generally common species. However, this species declined substantially (90% decline) following extensive coral loss in the central Great Barrier Reef in 2001 (Pratchett et al. 2006) and the population has shown no evidence of recovery (Pratchett et al. 2009). Declines in other parts of its range are unknown.|
|Habitat and Ecology:||This species inhabits coral-rich areas of lagoons, seaward reefs, and reef flats. Occurs as individuals or in pairs, but noted to form aggregations, possibly to mass-spawn (Pratchett et al. 2006). It is an obligate corallivore, but feeds on both hard and soft corals (e.g., Pratchett 2005). It recruits to shallow coral reef habitats with rich coral growth, settling among branching Montipora.|
|Use and Trade:||This species is frequently exported through the aquarium trade (Pyle 2001). Approximately 25,000 individuals were traded between 1988-2002 (Global Marine Aquarium Database 2009).|
|Major Threat(s):||Relies on live coral for food and recruitment, and has declined significantly following climate-induced coral depletion on the Great Barrier Reef (Pratchett et al. 2006). However coral bleaching and coral loss has been patchy throughout the Indian and Pacific Ocean, and localized declines due to coral loss have not substantially affected the global population. There are no apparent major threats other than coral loss.|
|Conservation Actions:||There appear to be no species-specific conservation measures in place. This species is present within marine protected areas. Data is required to establish effects of extensive aquarium collecting for this species. Monitoring of this species is needed in conjunction with coral monitoring.|
