A school of koi fish, predominantly orange with some black and white markings, swim in murky water, their mouths open as if feeding. The camera angle is from directly above the water, providing a close-up view of the fish. Sunlight appears to be filtering through the water, illuminating the fish and creating reflections on the surface. Some fish are stacked on top of each other, indicating a dense gathering. The overall impression is of a lively and active aquatic environment.
