Maturity: Lm ?  range ? - ? cm
Max length : 25.0 cm TL con đực/không giới tính; (Ref. 9710)
Các tia vây lưng cứng (tổng cộng) : 8; Các vây lưng mềm (tổng cộng) : 27 - 29; Tia cứng vây hậu môn: 3; Tia mềm vây hậu môn: 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.
