pond filled with a large number of koi fish

pond filled with a large number of koi fish. The fish are predominantly red and white, with some solid red and solid white individuals as well. They are actively swimming and moving around in the water. The water is dark, and the bottom of the pond is not clearly visible. There is some greenery around the edge of the pond, including grass and what appears to be a metal fence or structure. The camera appears to be stationary and focused on the pond from an elevated position.
