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.

Web Edition (https://www.trussel2.com/acd/).; obscura: From the Latin obscurus, meaning indistinct and inconspicuous, referring to the fish in general..
