Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 45.0 cm TL male/unsexed; (Ref. 9710)
Inhabits coastal reefs to at least 30 m (Ref. 9710). Adults often found in pairs inside caves (Ref. 9710, 48636). Juveniles settle in very shallow inshore habitats with short filamentous algae growth on rock or dead coral substrates (Ref. 48636). Feeds on sponges and tunicates (Ref. 48391). Undergoes a complete color transformation from the juvenile to adult stage. Regularly exported, e.g. from Sri Lanka, for the aquarium trade.
