**Betta fish **are a type of freshwater fish that belong to the gourami family. They are native to Southeast Asia, where they live in shallow water of marshes, ponds, or slow-moving streams. Betta fish are also known as Siamese fighting fish because of their aggressive behavior towards other males and incompatible tank mates. Betta fish have a unique organ called the labyrinth that allows them to breathe atmospheric air. This helps them survive in low-oxygen environments.
