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 soft rays (total): 9 - 12; Anal soft rays: 27 - 29. Distinguished from Betta burdigala in the following characters: presence of lateral iridescent blotch in males (vs. absence); black pelvic fin tip (vs. white); fewer dorsal fin rays (9-12 vs. 14-15); fewer subdorsal scales (7-8 vs. 11-11 1/2); more anal fin rays (27-29 vs. 24-26); more predorsal scales (18-21 vs. 15-16); greater total length (132.7-138.5% SL vs. 131.0-132.3% SL); smaller postorbital length (14.3-15.5% SL vs. 16.7-17.4); smaller dorsal fin base length (15.2-20.4% SL vs. 26.8-28.6). Can be differentiated from Betta miniopinna in the following characters: body red in color (vs. black); presence of lateral iridescent blotch in males (vs. absence); black pelvic fin tip (vs. white); presence of iridescent green spots on median fins (vs. absence); greater postorbital length (14.3-15.5% SL vs. 12.3-13.3); and smaller pelvic fin length (7.8-8.8% SL vs. 8.7-12.0) (Ref. 56386).

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 (0.00376 - 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).

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).

Price category (Ref. 80766): Unknown.
