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.

Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
A paternal mouth brooder, exhibiting the typical egg exchange between female and male. After the nuptial embrace, the female picks up the fertilized egg from the male's curved body, proceeds to transfer the eggs to the male for oral brooding by spitting out the eggs and the male gulps the eggs into its buccal sac. Male sometimes rejects the eggs, but the female continues spitting and gulping the eggs until the male finally accepts. This process continues until all the fertilized eggs have been transferred, then another bout of egg laying occurs with the whole procedure repeated.亞洲: 婆羅洲。
