The video shows a white fish with a long body and fins swimming in the water. The fish has a small, brown worm in its mouth. The background is dark, and there are no other visible objects or creatures in the water. The fish moves slowly and gracefully, with its fins undulating gently. The worm appears to be wriggling slightly, but the fish does not seem to be bothered by it. The lighting is dim, casting a soft glow on the fish's body and highlighting its sleek form. There are no visible titles, subtitles, or informative text in the video.
