Max length : 18.0 cm TL Männchen/unbestimmt; (Ref. 4392)
Rückenflossenstacheln (insgesamt) : 9; Rückenflossenweichstrahlen (insgesamt) : 13 - 14; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 12 - 13. Juveniles are black with numerous longitudinal white streaks (Ref. 1602).
Inhabit lagoon and seaward reefs, along the upper edges of coral-rich areas (Ref. 9710, 58534). Benthopelagic (Ref. 58302). May be solitary or found in small group (Ref. 90102). Juveniles are encountered in exposed outer reef flats (Ref. 1602). Feed on a wide variety of small invertebrates as well as fish eggs.
Pelagic spawner. Females migrate to spawning sites, larger females travel long distances to downcurrent areas than smaller ones to protect the eggs from becoming prey to larger reef fishes (Ref. 32198). Spawning sites are chosen by the females irregardless of the males occupying them (Ref. 32198). Females spawn in more than one spawning site, each site occupied by more than one male, which are either territorial or non-territorial (Ref. 32198). After spawning, they return individually to their home ranges without passing through other spawning sites (Ref. 32198). Some females on the other hand change sex after spawning (Ref. 32198). As males, they begin to establish territories in the spawning sites, even to those they visited before the sex change (Ref. 32198). This observation support the suggestion (Warner's 1985, 1986) that females stored information on spawning sites by migrating to various sites which aided in the acquisition of a mating territory after changing sex (Ref. 32198).
