The video shows a close-up of a fish tank with a white air pump attached to the side. The pump is connected to a blue tube that leads out of the tank. The tank is filled with water and has a layer of small, smooth rocks at the bottom. The water is clear, and there are no fish visible in the tank. The air pump is turned on, and bubbles can be seen rising to the surface, indicating that the pump is functioning properly. The lighting in the room reflects off the water, creating a serene and calming effect.
