In the video, a person is seen holding a white and black device in their hand. The device is being used to clean a fish tank. The person is moving the device around the tank, presumably to remove dirt and debris from the water. The fish in the tank can be seen swimming around, seemingly undisturbed by the cleaning process. The tank itself is filled with water and has various decorations and plants inside. The person's hand is steady as they hold the device, and they appear to be focused on the task at hand. The video provides a clear view of the cleaning process and the fish tank's environment.
