Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 9; членистые (мягкие) лучи анального плавника: 7. Black stripe from eye to caudal fin; nearly complete lateral line, with only last few scales lacking pores (Ref. 12693).
Occurs in a variety of habitats (Ref. 27732): ditches, ponds, canals, haors, streams, rivers and inundated fields (Ref. 1479). Inhabits mainly sandy streams and rivers (Ref. 6028). Found in medium to large rivers and brooks of the middle Mekong (Ref. 12975). In the Mekong basin, this species is usually associated with large, slow flowing rivers, usually with turbid waters (Ref. 43281). Sometimes forms large schools. Feeds mainly on aquatic insects and detritus. A surface feeder (Ref. 1479). Spawning sites are found in rivers and ponds (Ref. 33813). Mature adults probably breed during the rainy season. Hardy and adaptable in the aquarium.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00491 - 0.01545), b=3.01 (2.86 - 3.16), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.1 se; based on diet studies.
Generation time: 1.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (K=1.10).
Fishing Vulnerability (Ref.
59153): Low vulnerability (13 of 100).
