The video shows a close-up of a fish tank with a blue background. A plastic bag is placed inside the tank, and the fish are seen swimming around it. The water is clear, and the fish are of various sizes and colors. The plastic bag appears to be floating in the water, and the fish are swimming around it, some even swimming inside the bag. The video is shot from above the tank, and the camera moves slightly to capture different angles of the fish and the plastic bag.
