Βιολογία     Γλωσσάρι (π.χ. epibenthic)

Inhabit deep, protected lagoons and channels, and the deeper parts of outer reef slopes. Juveniles are often solitary while adults occur in pairs (Ref. 1602, 48636). A planktivorous species that generally remains within a few meters of the reef. Juveniles may sometimes pick on parasites on the epidermis of other fish (Ref. 5503). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
