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/).
Eponymy: In Greek mythology, Persephone was the queen of the Underworld -the equivalent of the Roman goddess Proserpine (q.v.). The name was given in fanciful allusion to the fish’s dark and sombre colouration. (Ref. 128868), visit book page.
