Arowana
Arowana is an ancient fish, belonging to the family Leptospira. Its reproductive ability is very weak. It is very strange that females lay eggs and males hatch and feed in their mouths. Because of its two beards, shiny scales and ancient life experiences, people naturally associate it with the mysterious dragon and call it "arowana".
Arowana is regarded as sacred fish in Southeast Asia, Hong Kong, Macao and Taiwan, and places where overseas Chinese are concentrated. In Wang's hometown, people think it can be used as a feng shui fish to ward off evil spirits. Arowana, in particular, was listed as a class A protected animal by the Washington Wildlife Protection Treaty at 1980. In Hongkong, Macau and Taiwan Province, the price of one-stop fish is more than one million yuan, which is regarded as a symbol of family wealth and status.
