Environment: milieu / climate zone / depth range / distribution range
Ecologia
marinhas associadas(os) a recifes; intervalo de profundidade 0 - 61 m (Ref. 58302), usually 5 - 40 m (Ref. 27115). Tropical; 28°N - 26°S

Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 25.0 cm TL macho/indeterminado; (Ref. 9710)
Espinhos dorsais (total) : 8; Raios dorsais moles (total) : 27 - 29; Espinhos anais: 3; Raios anais moles: 25 - 26. Gill rakers on anterior row 21-25, on posterior row 25. Juveniles differ greatly from adults. They have deeper bodies and are bright orange-red with numerous dark chevrons. Adults appear uniformly black from a distance but actually have numerous dark green horizontal pinstripes.
An uncommon species that inhabits seaward rocky or coral reefs (Ref. 9710). Juveniles found in relatively deep coral rich areas (Ref. 42056). Benthopelagic (Ref. 58302). Feeds on film algae (Ref. 89972). Minimum depth reported taken from Ref. 128797.
