The video shows a turtle swimming in a tank with a fish. The turtle is seen swimming around the tank, while the fish swims in the background. The tank is filled with water, and there are rocks and plants visible in the background. The turtle appears to be a common pet turtle, and the fish is not clearly identifiable. The turtle moves slowly and gracefully through the water, while the fish swims more actively. The lighting in the tank is bright, and the water is clear, allowing for a good view of the turtle and fish.
