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. Web Edition (https://www.trussel2.com/acd/).; pallifina: From the Latin pallidus (meaning pale) and finis (meaning boundary), referring to the unique coloration of the bordered anal and caudal fins of the females..

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0 - 1; Dorsal soft rays (total): 6 - 9; Anal spines: 1 - 2; Anal soft rays: 26 - 31. Differs from the other members of the Betta unimaculata group by the following combination of characters: hyaline subdistal band on anal and caudal fins of female; lanceolate caudal fin in adults; body brownish; lower half of caudal fin with dark distal edge; vertebrae 31-33 (mode 32); anal-fin rays 27-32 (mode 30); dorsal-fin rays 7-9 (mode 8); pectoral fin rays 11-14 (mode 13); subdorsal scales 5 - 6 1/2 (mode 6): lateral scales 32-34 (mode 33); predorsal scales 21-26 (mode 23); predorsal length 64.6-69.4% SL; head length 26.8-33.4% SL; length of anal-fin base 47.4-57.7% SL; length of dorsal-fin base 9.3-12.5% SL; lower jaw length 30.6-39.6% HL (Ref. 56613).

Facultative air-breathing (Ref. 126274); Found in headwater habitats (Ref 56613). Probably a paternal oral-brooder (Ref. 56613).

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): 3.3 ±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).
