There are 3 types of Asian Arowana - the Red, Gold and Green. For the Chinese, Red is a lucky color, as evidenced by the large amount of red used during Chinese New Year. This makes the Red dragon fish in high demand, and prices for a good quality red can easily fetch around USD5000. Gold is also considered lucky. However, it is surprising that Green variety is not very popular and is consider unlucky, especially in Cantonese speaking countries like Hong Kong, Shenzhen and Guangzhou. The Cantonese who keep a green Arowana in their home and often gamble are said to "shee tou meen cheang cheang" (lost till their faces turn green).
For the Chinese, the dragon is a symbol of good luck and prosperity. In the eyes of the Chinese, the dragon fish has the appearance and majesty of the Chinese Dragon, especially the scales - it resembles the scales of a Dragon.
When a Chinese businessman purchased one of these fishes, and strike a big fortune, the rumor will spread that he attribute his good luck to owning one of these fish. Soon, demand for this fish rocketed as many others hope that keeping a dragon fish will bring them luck.
Asian arowanas are considered "lucky" by many people, particularly those from Asian cultures. This reputation derives from the species' resemblance to the Chinese dragon, considered an auspicious symbol. The large metallic scales and double barbels are features shared by the Chinese dragon, and the large pectoral fins are said to make the fish resemble "a dragon in full flight."
In addition, positive Feng Shui associations with water and the colours red and gold make these fishes popular for aquariums. One belief is that while water is a place where chi gathers, it is naturally a source of yin energy and must contain an "auspicious" fish such as an arowana in order to have balancing yang energy. Another is that a fish can preserve its owner from death by dying itself.
