Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.4 cm TL male/unsexed; (Ref. 101568)
soft rays: 12 - 13. This species is distinguished by the following characters: bluish longitudinal stripe on the middle of the body; translucent white or pink, silvery on head and abdomen; caudal peduncle sometimes with a posteriorly placed black spot; characterized further by one or both caudal fin lobes having black tip; greatest depth of body 3.3-3.6 in SL (Ref. 90102).
Inhabits lagoon and coastal reefs, among coral and rocks (Ref. 4329). Lives sympatrically with A. notatus (Ref. 76833). Forms large schools (Ref. 559). Feeds during the day in currents above reefs as well as at night (Ref. 48635).
