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/); siamorientalis: Derived from Siam, the former name of Thailand, and orientalis, a Latin version for east, the region of the country where the fish is located.

Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 1 - 2; Raios dorsais moles (total) : 7 - 11; Espinhos anais: 3 - 5; Raios anais moles: 21 - 25. Can be diagnosed from other members of the Betta splendens group by having the following combination of characters: dark-brown to black body; black opercle with two parallel reddish vertical bars; red patches on dark brown to black opercular membrane; caudal fin rays with distal red crescent and thin black edge; no dark transverse bars on caudal fin; distal half of posterior anal fin rays red with a small red patch at distal tip; black and red from proximal pelvic fin base to the white tip (Ref. 93122).
Body shape (shape guide): fusiform / normal.
Facultative air-breathing (Ref. 126274); Inhabits shallow freshwater marshes, grass fields, and paddy fields. Found at the water edge (with dense vegetation) of ponds, lagoons, ditches, canals, and others water ways. Occurs in still waters and uses water plants as shelter to set up safe territory for building the bubble-nest, courtship, and hatching of fry. Cohabits with Trichopsis vittata, Trichopsis schalleri, Trichopsis pumila, Trichopodus trichopterus, Anabas testudineus, Lepidocephalichthys hasselti, Pangio anguillaris , Macrognathus siamensis, and Monopterus albus (Ref. 93122).
