Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 40.0 cm SL male/unsexed; (Ref. 30573)
Juveniles inhabit shallow protected areas, while adults prefer coastal reefs with heavy coral growth providing ample hiding places. Generally solitary or in pairs. Feeds on sponges, tunicates, and algae (Ref. 30573). The young are excellent aquarium fish and suitable for a community tank.
