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/).;  gladiator: From the Latin gladiator, meaning warrior or fighter, alluding to the aggressive behaviour of the species..

生物学特性     字汇 (例如 epibenthic)

Facultative air-breathing (Ref. 126274); This is an aggressive and territorial species which inhabits heath forest with acidic water. Single adults stay about one meter apart, usually together with a small number of juveniles. Individuals kept in captivity continuously fight and have to be kept separately, otherwise they would have killed each other (Ref. 56613).
