Marine; freshwater; brackish; reef-associated; amphidromous (Ref. 46888); depth range 0 - 78 m (Ref. 86942). Tropical; 30°N - 24°S
Indo-West Pacific: Red Sea and East Africa to the Tuamoto Islands, north to the Ryukyu Islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.0 cm TL male/unsexed; (Ref. 4343)
soft rays: 8 - 9. Characterized by red face with vertical blue lines; uniformly dark brown to light brown or bright green with a longitudinal thin red stripe; red stripe at the base of dorsal fins; absence of scales; complete pelvic fin frenum and basal membrane; depth of body at level of pelvic fins 2.6-3.0 in SL (Ref. 90102).
Marine species usually living on coral reefs but also recorded from pools, freshwater streams or lagoon mouths (Ref. 4343). Preys on copepods (Ref. 92840). Found on tabletop Acropora corals (Ref. 1602); a coral-commensal species (Ref. 72446). 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).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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).
