Create a highly detailed, surreal yin-yang composition featuring two koi fish in a 3D, photorealistic style. One fish is pure white with subtle black markings, representing the yang, and the other is jet black with metallic scales and subtle white markings, representing the yin. They are swimming in a dynamic circular motion, creating a swirling effect of black and white water currents. Surrounding the koi are delicate, blooming white lotus flowers with soft red centers, adding an ethereal touch. The background is a deep, misty atmosphere that enhances the contrast between the light and dark elements. The scene should evoke a sense of balance, harmony, and tranquility, with a focus on the intricate details of the fish scales, the flowing water, and the delicate petals of the lotus flowers
