Maturity: Lm ?  range ? - ? cm
Max length : 28.0 cm TL male/unsexed; (Ref. 9710); max. reported age: 15 years (Ref. 72479)
Occurs in coral rich areas of clear lagoons, channels, and protected outer reef slopes. Changes to adult pattern is dramatic, and intermediate stage are rarely seen (Ref. 48636). Often solitary. Feeds on sponges and tunicates. Uncommon (Ref. 9710). Highly prized aquarium export (Ref. 37816).
