Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Body shape (shape guide): short and / or deep; Cross section: compressed.
A diurnal feeder or substrate feeder. Primary food item are sponges supplemented by tunicates, algae, bryozoans, hydroids and eggs. Adults often range widely over the reef in pairs or loose aggregations while juveniles are territorial and solitary. Oviparous (Ref. 240), monogamous (Ref. 52884). Breeding occurs from midsummer to early fall and juveniles are most abundant from August through November.

Protogyny has been proposed for this species awaiting confirmation (Ref. 103751). Monogamous mating is observed as both facultative and social (Ref. 52884).
