A top-down shot shows a koi fish swimming in a narrow trough of water. The fish has large patches of orange, black, and white markings. The trough is flanked by stone structures on either side that are textured with layers of rock. The water is clear enough to see the bottom of the trough, which is brownish in color. In the bottom left corner, a small, dark-colored pump is visible, submerged in the water. The camera slowly zooms in on the fish as it swims in place.
