Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; brackish; pelagic. Tropical; 17°N - 4°S
Asia: Chao Phraya basin and Mekong basin in Laos, Thailand, Cambodia and Viet Nam; also from southern Borneo.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.0 cm SL male/unsexed; (Ref. 12693)
Dorsal spines (total): 0; Dorsal soft rays (total): 12 - 18; Anal spines: 0; Anal soft rays: 16 - 27. Body depth increasing with size of fish, belly sharply keeled, with 9 to 12 + 6 to 9 scutes. Pre-maxillae long and toothed; second supra-maxilla as long as or longer than blade of maxilla. Pectoral axillary scale at least 1/3 length of fin. No grey or silvery stripe along flank (Ref. 188). Last 2 rays of anal fin not forming a separate finlet (Ref. 43281).
Occurs in tidal zone of large rivers. Feeds mainly on planktonic crustaceans. Reported as non-migratory, may move short distances from the main river channels during high water periods. Used to produce prahoc and tuk trey (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00366 - 0.02072), b=3.03 (2.83 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.30 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 350 [183, 727] mg/100g; Iron = 2.21 [1.27, 3.92] mg/100g; Protein = 18.4 [17.3, 19.5] %; Omega3 = 0.487 [0.250, 0.950] g/100g; Selenium = 31.9 [14.8, 69.3] μg/100g; VitaminA = 66.9 [16.3, 273.1] μg/100g; Zinc = 2.54 [1.70, 3.76] mg/100g (wet weight); based on
nutrient studies.
