A close-up shot shows several koi fish swimming in murky water. The fish are colorful, with patterns of orange, white, and black. Some of the fish are close to the surface, and their scales are visible. The water is disturbed by the movement of the fish, creating ripples and bubbles. There are some green plants or algae visible in the background, along with some white foam on the surface of the water. The lighting suggests it is daytime.
