The video shows a person's hand holding a plant with small green leaves and stems. The plant is being placed into a fish tank that already has some green plants and leaves floating on the surface of the water. The fish tank appears to be well-maintained, with clear water and no visible fish or other aquatic creatures. The person's hand is steady as they carefully place the plant into the water, ensuring it doesn't disturb the existing plants. The lighting in the room is bright, and the focus is on the action of placing the plant into the fish tank.
