Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Body shape (shape guide): short and / or deep; Cross section: compressed.
Diurnal grazers on sessile invertebrates and algae but specializes to a larger extent on sponges. They also feed on plankton. Reproduction occurs in late summer. Females are more territorial and form pair bonds with the males. Oviparous (Ref. 240). Monogamous and always in home-ranging pairs, that is they do not defend an exclusive territory (Ref. 52884). Sometimes forms mixed aggregations with Pomacanthus zonipectus (Ref. 9333). Cleaning behavior has been observed in juveniles.

Spawn daily throughout the lunar cycle (Ref. 240). Protogyny has been proposed for this species awaiting confirmation (Ref. 103751). Monogamous mating is observed as both facultative and social (Ref. 52884).
