Betta is a large genus of small, often colorful, freshwater ray-finned fishes in the gourami family (Osphronemidae). By far the best known Betta species, commonly known as the Siamese fish. The various bettas can be divided into two groups, based on their spawning behaviour: some build bubble nests, such as B. splendens, while others are mouthbrooders, such as B. picta. The mouthbrooding species are sometimes called "pseudo bettas", and are sometimes speculated to have evolved from the nest-builders in an adaptation to their fast-moving stream habitats.
