Barito River
"Betta pallifina" is only known from clear forest streams in the upper Barito River basin in Central Kalimantan, Indonesia. These streams have soft sandy or leaf-litter bottoms with dense marginal plants and patches of aquatic vegetation. The water temperature in which these fish are found is typically 77-79 °F (25-26 °C), with the pH ranging from 6.6-7.4.
