Épines dorsales (Total) : 1; Rayons mous dorsaux (Total) : 8; Épines anales: 2 - 3; Rayons mous anaux: 22 - 24; Vertèbres: 29 - 30. Differs from Betta rubra bypossessing the following characters: a continuous black postorbital stripe extending up to opercle edge (vs. interrupted stripe); broad suborbital stripe below eye forming a triangular black mark (4-5 scale rows wide, vs. 2-3); body coloration less intense with wider interspaces between the black body bars; fewer anal-fin n rays (mode 25, vs. 27); greater number of subdorsal scales (6-7 vs. 5-5 ½); greater number of lateral scales (mode 31, vs. 30); greater number of vertebrae (mode 30, vs. 29); longer dorsal-fin base length (13.0-18.4, vs. 11.0-13.4% SL); and smaller maximum size (35.4 vs. 42.1 mm SL) (Ref. 93059).
Facultative air-breathing (Ref. 126274); Occurs in lowland hillstream and acid water swamp habitats. Found in clear to brown-water habitats, from secondary forest to plantation and farmland environments. Syntopic with Osteochilus jeruk, Rasbora jacobsoni, Rasbora kluetensis (Cyprinidae); Nemacheilus tuberigum (Nemacheilidae); Mystus punctifer (Bagridae); and Ompok brevirictus, Kryptopterus piperatus (Siluridae) (Ref. 93059).
