Indo-West Pacific. East Africa to Fiji, north to Taiwan, south to the Norfolk Island.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL male/unsexed; (Ref. 2334)
(total): 12 - 14;
soft rays: 21 - 25. Dark spot distally between 1st 2 dorsal spines; (Ref. 4404). Males with about 6 dusky bands on body; females with bands that tend to form vertical rows of dusky spots; dusky spots on dorsal and caudal fins; anal fin uniformly dusky (Ref. 4404).
Euryhaline. Adults are often found in mangrove areas (Ref. 9962). They inhabit sheltered rocky shorelines and mangroves (Ref. 37816). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
