The video shows a close-up of a fish tank with green plants and rocks. There are several small fish swimming around in the tank. The fish are of different colors, including blue, red, and orange. The plants are lush and green, and the rocks are brown and rugged. The water in the tank is clear, and bubbles can be seen rising to the surface. The fish are swimming in different directions, some near the plants and others near the rocks. The video is shot from the outside of the tank, and the camera moves slightly to capture different angles of the fish and plants.
