Forms permanent harem groups composed of a single male and several smaller females (Ref. 55367). A monandric species (Ref. 55367). Oviparous (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). While protogyny was originally proposed for this species such as the report of length at sex change = 6.8 cm TL (Ref. 55367), recent studies confirmed gonochorism in the form of non-functional hermaphroditism (Ref. 103751).中太平洋東部: 大洋洲東南方包括社會群島, Tuamoto 島, 皮特凱恩島聚集, 與拉帕島。
