This media file shows a close-up, top-down view of several koi fish swimming in a tank of dark, murky water. A stream of water is pouring into the tank from above, creating ripples and splashing on the surface. The fish are predominantly white with red markings, and their fins are visible as they move through the water. The bottom of the tank appears to be covered with a dark, textured material, possibly gravel or a mat. The lighting is bright, coming from above and to the right, creating some glare on the water's surface and illuminating the fish. The overall impression is of a feeding or water change occurring in an aquarium. There is no visible text in the media file.
