Οικολογία
Θαλασσινό(ά) Υφαλόφιλο(α); εύρος βάθους 0 - 61 m (Ref. 58302), usually 5 - 40 m (Ref. 27115). Tropical; 28°N - 26°S

Μέγεθος / Βάρος / Age
Maturity: Lm ? range ? - ? cm
Max length : 25.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 9710)
Ραχιαίες άκανθες (συνολικά) : 8; Μαλακές ραχιαίες ακτίνες (συνολικά) : 27 - 29; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 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.
