Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 13 - 14; Rayons mous dorsaux (Total) : 15 - 17; Épines anales: 3; Rayons mous anaux: 15 - 17. Black spot with white or bluish edges on its sides (Ref. 5372).
Body shape (shape guide): short and / or deep.
Adults are usually seen alone or in pairs (specially during spawning) but occasionally in small groups, particularly in the vicinity of staghorn Acropora and Goniopora (Ref. 5503) thickets. Diet consists of live corals which makes it difficult to maintain in captivity (Ref. 4858). Little intraspecific nor interspecific aggressiveness (Ref. 5503). Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205).
