Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 9710)
Found on coral slopes (Ref. 9710) Juveniles in large groups at base of reef, sometimes with H. diphreutes; adults usually solitary or paired, occasionally in groups (Ref. 9710). Feed on zooplankton and benthic invertebrates (Ref. 9710). Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Distinct pairing (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
