Ground color light brown. Dark chevron markings over most of body. Snout-eye band and opercular bar reddish. Caudal fin with broad black triangular or diamond shaped patch bordered with yellow.
Usually found in shallow waters at depths of 2 to 12 m in the close association with branching corals.
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.
