The image shows a large group of koi fish swimming in a pond. The fish are predominantly orange and white in color, with some yellow and black markings on their bodies. The water is dark and there are small ripples visible on the surface. The pond appears to be made of concrete and there is a concrete wall on the right side of the image. The koi are closely packed together, creating a large number of them. The image is taken from a low angle, looking up at the fish.
