Butterfly fish symbolizes wealth, auspiciousness, health and happiness, and is called "auspicious fish", "feng shui fish", "living gem in water" and "king of ornamental fish". Butterfly fish, as its name implies, has a lion's head, seven fins, a small head with a flat mouth bent downward, a short body, a tail fin as elegant as a butterfly's wings, and a white body, which is double-sacred under the light, just like a fairy. The group tour is domineering and very beautiful.
