Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 6 - 7; Raggi dorsali molli (totale) : 10 - 11; Spine anali: 1; Raggi anali molli: 8 - 9. Characterized by dark brown body color and lighter brown to reddish head with five vertical blue lines; young fish with additional vertical lines on body; absence of scales; complete pelvic fin frenum and basal membrane; depth of body at level of pelvic fins 2.6-2.9 in SL (Ref. 90102).
Facultative air-breathing in the genus (Ref. 126274); Found in groups among branches of Acropora coral (Ref. 9710, 48637); a coral-commensal species (Ref. 72446). Feeds on small invertebrates and zooplanktons (Ref. 89972). Monogamous (Ref. 52884). The male takes care of eggs deposited on a coral branch (Ref. 32163). Has the ability to change sex in both directions to favor reproductive success (Ref. 32163).

The male takes care of eggs deposited on a coral branch (Ref. 32163). Has the ability to change sex in both directions to favor reproductive success (Ref. 32163). Monogamous mating is observed as both obligate and social (Ref. 52884).
