Comments: Inhabits outer reef slopes, over rubble, algae, or coral (Ref. 9710). Occurs in small groups of mix sexes but females outnumber males greatly (Ref. 48636).  Swim close to the bottom and females swim in small groups.  Males swim around them and often hurry from one area to another where there are groups of females.  Some juveniles are secretive and often single or small groups amongst the rubble (Ref. 48636).
