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/); pallida: From the Latin word 'pallidus', meaning pale or colorless, compared to some of its congeners which are more colorful.

Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 8 - 9; Espinas anales: 2; Radios blandos anales: 24 - 25. Diagnosis: Caudal fin of males lanceolate, body with an uninterrupted dark central lateral stripe, dorsal and ventral margins clearly defined, distinct caudal spot lacking, the lower lateral stripe is posteriorly disrupted into wide-spaced small blotches (Ref. 54318).
Body shape (shape guide): fusiform / normal.
Facultative air-breathing (Ref. 126274); Specimens were collected in February 2005 in a slowly flowing creek which was only 20 to 50 cm deep; the water was clear and slightly tanned, bed covered densely with leaf litter; water
data pH 6.3, 82 µS/cm and 25.5°C. From another creek, where the species was collected, pH 6.5, 69 µS/cm and 26.6 °C (Ref. 78499).
