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.

Body shape (shape guide): fusiform / normal.
Facultative air-breathing (Ref. 126274); Occur in standing waters of floodplains, canals, rice paddies (Ref. 12693) and medium to large rivers (Ref. 12975). Feed on zooplankton, mosquito and other insect larvae (Ref. 12693). Air breather and bubble nest builder. Used in behavioral studies (Ref. 4537). Males will fight each other. The many colorful varieties are popular aquarium fish, however, the holding of the males in very small containers should be discouraged (Ref. 1672). Aquarium keeping: sexes should be kept separate unless for mating, and that only one female should be brought into the breeding tank measuring about 20-30 L (http://www.kampffischnet.de).
