Clés d'identification | Morphologie | Morphométrie
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 and always in home-ranging pairs, that is they do not defend an exclusive territory (Ref. 52884). Breeding occurs from midsummer to early fall and juveniles are most abundant from August through November.
