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.

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 1; Rückenflossenweichstrahlen (insgesamt) : 8; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 27. Distinguished from Betta chloropharynx in the following characters: median black throat spot (vs. two rounded black marks); spotted opercle (vs. non-spotted); opercle with black lower margin (vs. yellow margin). Differs from Betta hipposideros in the following characters: median black throat (vs. horse-shoe shape mark); spotted opercle (vs. non-spotted); opercle with black lower margin (vs. yellow or brown); more postdorsal scales (mode 10 vs. 9 1/2). Can be differentiated from Betta renata in the following characters: black median spot (vs. kidney-shaped mark); absence of dorsal and caudal transverse bars (vs. presence); fewer subdorsal scales ( mode 5 1/2 vs. 6 1/2); fewer postdorsal scales (mode 10 vs. 12); more anal fin rays (mode 30 vs. 29); and more lateral scales (mode 32 vs. 31) (Ref. 56386).
Body shape (shape guide): fusiform / normal.
Facultative air-breathing (Ref. 126274); Inhabits swamps as well as adjacent streams, usually in relatively shallow water about a meter or so in depth with dense vegetation growing along the banks and under shade.
