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/).; mahachaiensis: The specific name is derived from its common Thai name for a subdistrict of Samut
Sakhon Province, viz. Maha Chai..

Dorsale stekels (totaal): 0 - 2; Dorsale zachte stralen (totaal): 8-11; Anale stekels 3-4; Anale zachte stralen: 22 - 26. Distinguished from other species in the Betta splendens group by the combination of the following characters: opercle with two parallel iridescent green to bluish-green vertical bars; brown-to-black opercular membrane without red streaks or patches; dorsal, caudal, and anal fin rays brown to black contrasting with iridescent green or bluish-green interradial membranes; dorsal fin with at least its proximal two-thirds having transverse black bars; caudal fin without dark transverse bars, small black rounded marks flanking the internal rays on interradial membranes; pelvic fin brown to black with iridescent green/bluish-green front margin and white tip; an iridescent green to bluish-green appearance on the brown-to-black body background; head length 24.9-31.2% SL; postdorsal length 17.1-25.2% SL; length of dorsal fin base 12.2-19.3% SL; pelvic fin length 21.2-49.6%; pectoral fin length 15.4-21.3% SL; and orbit diameter 22.8-29.7% SL (Ref. 92085).
Facultative air-breathing (Ref. 126274); Encountered in nipa palm (Nypa fruticans) swamps, especially in the water-holding phytotelma of the palm bract, which the pair use for bubble-nest building, courtship, and hatching of fry (Ref. 92085).
