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.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0 - 1; Dorsal soft rays (total): 8 - 9; Anal spines: 2; Anal soft rays: 27 - 28. Differs from Betta hipposideros in the following characters: µ-shaped black throat mark (vs. horseshoe-shaped black mark); absence of both dorsal and caudal transverse bars (vs. presence); fewer subdorsal scales (mode 5-6 vs. 6 1/2). Distinguished from Betta renata in the following characters: µ-shaped black throat mark (vs. kidney-shaped); absence of both dorsal and caudal transverse bars (vs. presence); non-spotted opercle (vs. spotted opercle); opercle with yellow lower margin (vs. black margin); fewer subdorsal scales (mode 5-6 vs. 6 1/2). Can be differentiated from Betta spilotogena in the following characters: µ-shaped black throat mark (vs. black median spot); non-spotted opercles (vs. spotted opercle; and an opercle with yellow lower margin (vs. back margin) (Ref. 56386).

Facultative air-breathing (Ref. 126274); Occurs in a secondary forest area in a pool among leaf litter.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00377 - 0.02651), b=2.97 (2.74 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

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).
