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/)..

Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 1; Mjukstrålar i ryggfenan (totalt): 7-9; Taggstrålar i analfenan 2; Mjukstrålar i analfenan: 24 - 28; Ryggkotor: 29 - 31. Can be differentiated from other members of the Betta akarensis group by possessing the following combination of characters: opercle with interrupted second postorbital stripe; eye color yellow when alive; anal-fin rays 26-30 (mode 28); subdorsal scales 5 1/2-7 (mode 6); lateral scales 30-31 9mode 31); predorsal scales 22-24 (mode 23); postdorsal scales 9-11 (mode 10); preanal length 42.6-45.7% SL; head length 31.4-33.3% SL; length of anal-fin base 54.8-58.5% SL (Ref. 56613).

Biologi     Ordlista (t.ex. epibenthic)

Facultative air-breathing (Ref. 126274); Found in shallow (less than 0.5 m depth) peat swamps with substrate consisting mainly of detritus, leaves and peat (Ref. 12293). An oral brooder (Ref. 56613).

Assumed to be the same as in Betta picta, i.e., the male is carying the aggs in his mouth for about 10 days.

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).
Trofisk nivå (Ref. 69278):  3.2   ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
