Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 12; Raggi dorsali molli (totale) : 15 - 16; Spine anali: 2; Raggi anali molli: 12 - 13. Exhibits geographic color variations.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Adults inhabit coral and rocky reefs (Ref. 9334). Omnivorous (Ref. 9334). Adults are territorial and aggressive, vigorously driving off other fishes and certain invertebrates from their feeding and reproductive territories. They graze on algae and invertebrates including tubeworms, small crustaceans, and the tentacles of anemones (Ref. 28023). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
