What is a Betta fishes niche?

Betta fish, also known as Siamese fighting fish, occupy a niche in freshwater habitats, primarily in shallow waters like rice paddies, swamps, and slow-moving streams in Southeast Asia. They thrive in environments with dense vegetation, which provides shelter and breeding grounds. Their ability to breathe atmospheric oxygen via a labyrinth organ allows them to survive in low-oxygen conditions, giving them a competitive edge in their natural habitat. Bettas are also territorial and exhibit aggressive behaviors, particularly during mating seasons, influencing their interactions with other species.
