The image shows a large group of koi fish swimming in a pond. The fish are of different sizes and colors, including orange, white, and black. They are all facing the same direction and appear to be closely packed together. The water is dark and murky, and there are small rocks visible at the bottom of the image. The koi are swimming in different directions, with some overlapping each other. The image is taken from a low angle, looking up at the fish.
