Territorial species which occur in shallow lagoon and semi-protected seaward reefs (depth 2-30m, usually down to 10m). Associated with tabular and staghorn Acropora corals.
An obligate corallivore, feeds exclusively on the polyps of Acropora corals with an apparent strong dependence on (Acropora hyacinthus). Solitary or in pairs. Juveniles
secretive among coral branches. Oviparous. Form pairs during breeding. Distinct pairing. Listed as Near Threatened due to strong dependence on corals that are subject to
coral bleaching and has shown a decline in tandem with the coverage of said corals.
This species is not protected or subject to fishery regulations. It may be subject to net and trap fisheries but typically would be released.
