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/); stiktos: From the Greek noun stiktos meaning dappled, spotted, in reference to the rows of diagnostic round spots on the dorsal fin.
