Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 4858)
Inhabits rock and coral reef at depths of 30 to at least 60 m. Occurs in aggregations that swim high above the bottom; harems of 2-5 individuals. Feeds mainly on zooplankton, although some benthic material is probably consumed (Ref. 4858). Almost never exported through the aquarium trade (Ref. 48391).
