The long things under a betta fish's chin are called "pectoral fins." These fins are used for steering, balancing, and maneuvering while swimming. Betta fish also have unique elongated fin shapes that contribute to their graceful movement and vibrant appearance. The pectoral fins can be particularly prominent in male bettas, enhancing their display during courtship or territorial displays.
