While there have been no declines documented, this species is dependent on live coral cover, which may make it susceptible to habitat loss. However, it has a relatively wide distribution, apparently large population and no obvious major threats other than coral loss. It is listed as Least Concern.
|Range Description:||This species occurs in the Red Sea and the Gulf of Aden, east to the Arabian Sea coast of Oman (Allen 1980, G.R. Allen pers. comm. 2006). It is found to a depth of around 20 m.|
Native:Djibouti; Egypt; Eritrea; Israel; Jordan; Saudi Arabia; Somalia; Sudan; Yemen

It is generally common throughout the Red Sea, particularly in the Gulf of Aqaba and farther to the south off Jeddah and Port Sudan; populations are stable (Allen 1980, G.R. Allen pers. comm. 2006).
|Habitat and Ecology:||This species is found in lagoonal and fringing coral-rich reefs with clear water (Allen 1980, G.R. Allen pers. comm. 2006). Solitary individuals or pairs are most often encountered, with small shoals less frequent. It is an obligate corallivore, but gastropod eggs and anemones are also consumed. Juveniles inhabit a single coral head until they reach maturity (Allen 1980, G.R. Allen pers. comm. 2006).|
This species relies on live coral for food and/or recruitment, and may therefore decline in abundance following climate-induced coral depletion (Pratchett et al. 2008). Currently there has been no documented declines associated with coral loss, and there appear to be no other major threats to this species.
There appear to be no species-specific conservation measures in place. This species is present within marine protected areas. Monitoring of this species is needed in conjunction with coral monitoring, as well as determination of the degree of co-dependence between this species and corals.
