Natural Habitat & Betta Fish Behavior
Betta fish originate from the slow-moving, shallow waters of Thailand, Cambodia, and Vietnam. They inhabit rice paddies, swamps, and small streams with warm, oxygen-deficient water, using their labyrinth organ to breathe atmospheric air.
In captivity, Betta fish are known for their territorial behavior, especially males, which should not be housed together. Females can coexist in Betta sororities under specific conditions. Bettas are intelligent, responsive to their owners, and can even be trained to perform tricks.
