Pelagic spawner. A monandric species (Ref. 55367). Females are induced to change sex by removal of males from social groups (Ref. 38802). Sex-reversal is completed in 2-4 weeks after male removal in the area, or 170-280 days in an all female group (Ref. 34185, 34249, 34250). Length at sex change = 5.0 cm TL (Ref. 55367). Also Ref. 103751.
Successful males spawn nightly with successive females (Ref. 37816).
