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.

Espinhos dorsais (total) : 1; Raios dorsais (total) : 9 - 10; Espinhos anais: 2; Raios anais : 25 - 26. Distinguished from Betta burdigala in the following characters: body black in color (vs. red); no iridescent green spots on median fins (vs. presence); fewer dorsal fin rays (10-11 vs. 14-15); fewer subdorsal scales (8 vs. 11-11 1/2); more anal fin rays (27-28 vs. 24-26); more predorsal scales (18 vs. 15-16); smaller dorsal fin base length (16.0-24.6% SL vs. 26.8-28.6); smaller postdorsal length (12.3-13.3% SL vs. 16.7-17.4); greater predorsal length (56.2-65.4% SL vs. 52.8-54.9); and smaller preanal length (37.9-42.6% SL vs. 42.5-45.5). Can be differentiated from Betta coccina in the following characters: absence of lateral iridescent blotch (vs. presence); body black in color (vs. red); white pelvic fin tip (vs. black); absence of iridescent green spots on median fins (vs. presence); smaller postorbital length (12.3-13.3% SL vs. 14.3-15.5); and greater pelvic fin length (8.7-12.0% SL vs. 7.8-8.8) (Ref. 56386).
Body shape (shape guide): fusiform / normal.
Facultative air-breathing (Ref. 126274); Occurs in shaded, acidic waters in a swamp forest, with leaf litter and soft mud substrate.
