"An overhead, bird's-eye view of two koi fish swimming in a calm, clear pond. The larger koi fish is vividly colored with white, orange, and black patches, while the other is a deep black-purple. The water is a rich, tranquil teal-green, with gentle ripples, soft reflections, and visible aquatic plants rising subtly from the pond's depths, contributing to a sense of depth and clarity. The lighting is soft and diffused, with delicate light ripples and soft reflections across the water's surface, creating a peaceful and serene atmosphere. The two koi fish are clearly spaced apart, swimming in distinct areas of the frame, gliding smoothly through the water. The fish should have sharp, vivid textures with defined edges and crystal-clear details, showcasing ultra-high resolution and ultra-sharp textures with subsurface scattering. The background water and plants should remain softly blurred and less defined, emphasizing the fish in sharp focus.
