The video shows a close-up of a fish swimming in the water. The fish has a reddish-brown body, with a long, thin tail and fins that are spread out. The fish's eyes are small and black, and its mouth is slightly open. The water around the fish is clear, and the background is blurred, but it appears to be a natural body of water. The fish moves slowly and gracefully through the water, with its fins and tail gently undulating. The video is shot from a side angle, giving a clear view of the fish's body and fins.
