Marine; brackish; freshwater; demersal; amphidromous (Ref. 59012); tropical; 19°N - 23°S -.

Asia: Indo-Australian Archipelago, including Indonesia, the Philippines, Borneo, Java, New Guinea, Vanuatu, New Caledonia, to northern Australia and the Andaman Sea. Reported from Palau (Ref. 6371) and the Ryukyu Islands (Ref. 559).

Maturity: L_m 7.0, range ? - ? cm
Max length: 12.0 cm TL male/unsexed (Ref. 7050); common length: 5.0 cm SL male/unsexed (Ref. 7242); max. published weight: 12.00 g (Ref. 7242).

Dorsal spines (total): 8; Dorsal soft rays (total): 9 - 10; Anal spines: 3; Anal soft rays: 9 - 10. Body very high, 50% of SL. Lateral line incomplete, but a few pored scales on a silvery midlateral band. Lower margin of inter operculum with few spines. The second spine of the first dorsal fin is strong and very long.

Found in brackish-water, mangrove, estuarine and freshwater-stream habitats, usually within 20 km of the sea (Ref. 2847). They occur at temperatures ranging from 28 to 32°C. Found in schools and migrate to freshwater. Mainly diurnal. A predominantly marine or estuarine spawner. Caught by hand and scoop nets (Ref. 7242).

A nonobligatory plant spawner.

Preferred temperature (Ref. 123201): 26.7 - 29.1, mean 28.4 °C (based on 1018 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00659 - 0.02000), b=2.96 (2.81 - 3.11), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.7 ±0.1 se; Based on diet studies.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Fec=29,000-310,000).

Fishing vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): Low; Very questionable: based on ex-vessel price for species in this family.
