Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 67 - ? cm
Max length : 65.0 cm TL male/unsexed; (Ref. 48635)
A generally uncommon species that inhabits seaward reefs (Ref. 9710). Juveniles inshore on algae and soft coral reefs, usually swimming well above the substrate, looking much like a basslet (Ref. 48635). Found in small groups (Ref. 11888). Feeds on fishes. Flesh tastes excellent. Solitary (Ref 90102).
