In the video, a person is seen holding a small plant with green leaves and placing it into a fish tank. The tank is filled with water and has a rocky background. The person's hand is visible as they carefully place the plant into the water. The plant is then shown floating in the water, with its green leaves swaying gently. The tank appears to be well-maintained, with clear water and no visible debris. The plant is the only object being added to the tank, and it is placed near the center of the frame. The video does not show any fish or other aquatic creatures in the tank.
