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.

Differs from other members of the Betta unimaculata species group by the following combination of characters: distinct black spot near caudal peduncle; body wormish; opercle blue; uniform caudal fin coloration; vertebrae 33-34 (mode 33); anal-fin rays 30-31 (mode 30); dorsal-fin rays 8; pectoral fin rays 12-13 (mode 13); subdorsal scales 5-5 1/2 (mode 5 1/2); lateral scales 32-34 (mode 33); predorsal scales 24; predorsal length 68.8-71.9% SL; head length 31.4-33.3% SL; length of anal-fin base 52.2-54.5% SL; length of dorsal-fin base 10.5-11.3% SL; lower jaw length 27.3-33.1% HL (Ref. 56613).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Facultative air-breathing (Ref. 126274); Inhabit more slow flowing areas of the headwater habitats (Ref. 34011). Found usually in ravines and isolated elevated pools. An adult and several juveniles are usually encountered in submerged leaf litter. Adults may take cover under floating leaves and are excellent jumpers, which may explain their presence in isolated elevated pools (Ref. 56613). Feed mainly on terrestrial insects and occasionally on aquatic invertebrates (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
Widerstandsfähigkeit (Ref. 120179):  hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
