Các tia vây lưng cứng (tổng cộng) : 1 - 2; Các vây lưng mềm (tổng cộng) : 9 - 12; Tia cứng vây hậu môn: 2 - 3; Tia mềm vây hậu môn: 24 - 28. Belongs to the Betta coccina species group but can be distinguished from the remaining species of this clade by having bright, greenish-colored flanks and unpaired fins (vs. body blackish without iridescent scales, or greenish iridescent scales restricted to the lateral blotch or the central parts of the flanks). Diagnosed from its geographic neighbor species Betta uberis by having 10-12 dorsal-fin rays (vs. 14-17 in B. uberis) (Ref. 93322).
Body shape (shape guide): fusiform / normal.
Facultative air-breathing (Ref. 126274); Found in peat swamps with depth of about 5 to 50 cm and with no water current. The water was shaded by trees and bushes. Collected among the aquatic and marsh plants. Forms bubble nest based on aquarium conditions (Ref. 93322).
