Dante koi fish should be in the East. Whether in China's Eight Diagrams Metaphysics or in the western Tarot cards, the East represents success and development. Because the whole body is red, it is best to put it in the east to replenish energy.
Gold and koi fish should be placed in the West. The west always represents money and social status, but because the west is a sunset and lacks the quality of "gold", putting gold and koi fish in the west is the most prosperous way to get rich.
Red, white, koi fish or tricolor koi fish should be placed in the south. North and South represent fame and family respectively. The south should be warm, but it is not allowed to emit strong light. Koi fish should be able to capture sunlight and collect heat. Therefore, red and white brocade or tricolor brocade is the most nourishing feng shui in the south because of its rich colors and soft light.
Koi fish should be placed in the north. In the north, due to the worst lighting and heavy yin, it is most appropriate to put a pair of mullet carp, so that suction yin can keep away evil spirits.
