Etymology: Betta: Malay/Javanese origin. Bleeker (1850, 1858) indicates Ikan Wadder Bettah as the local name of Betta trifasciata Bleeker, 1849 (now Betta picta, Valenciennes, 1846) in the Ambarawa Javanese dialect. Ikan Wader is a common Javanese name for smaller freshwater fishes, especially cyprinids (already used in Old Javanese). See Blust, R. & Trussel, S. Austronesian Comparative Dictionary.

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Body oblong, dusky or yellowish brown with 3 fainted dark stripes. Opercle with blue green patch, fins with iridescent blue, anal fin with dark margins. Pelvic fin short, anal fin base long, caudal fin rounded (Ref. 58784).

Facultative air-breathing (Ref. 126274); Inhabits limestone streams and marshes (Ref. 58784). The type locality was described as a pool of 10-15 m diameter, up to 10 m deep and the species was collected along the banks. Water data reported was 27 °C, pH 7.0, electric conductivity 530 µS/cm. Examined specimens were collected in a comparatively fast flowing, clear-water creek and were found between plants (Ref. 78499). Carnivorous, feeding on zooplankton and insects (Ref. 58784).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00376 - 0.02663), b=2.97 (2.75 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

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

Prijsklasse (Ref. 80766): Unknown.
