The video shows a small fish swimming in a tank. The fish has a shiny body with small, reflective scales that glisten as it moves. It has a long, slender body with a pointed snout and small fins. The fish is swimming near the bottom of the tank, which has a sandy bottom. The water is clear, and there are no other fish or objects in the tank. The fish moves gracefully, its fins undulating gently as it swims. The light in the tank highlights the shimmering scales on the fish's body, making it appear almost ethereal.
