Several colorful koi fish swim in a clear, indoor pond designed to resemble a natural rock pool. The pond features a pebbled bottom, large rocks forming the edges, and various green plants, including ferns and ivy-like foliage. In the background, a small waterfall cascades over stacked rocks into a darker section of the pond. Artificial lighting illuminates the scene, highlighting the fish and the water's clarity. The koi, varying in shades of orange, white, gold, and mottled patterns, swim actively, some congregating together while others move independently. The setting suggests a tranquil environment, possibly in a public aquarium or a large indoor space in Sochi, Russia. No text is visible.
