Three thousand years ago, there’s a saying in Taoism “You are not a fish; where do you know the joy of fish from?” But when you stand in front of the pond and watch these koi swim, it is not hard to discover the joy of the fish. Just like physiognomy, you would be able to tell if thekoi is healthy and happy by its nice form, its bright color and its speedy moves.

The word “koi” comes from Japanese, simply meaning "carp". There are many different colors of koi in the pond, the major named varieties include Kohaku, Taisho Sanke, Showa Sanke,Tancho. The Chinese call this kind of fish “Living diamonds” or ”Swimming art”. In the past, the Chinese see it as a symbol of successful career and blissful luck to the wealthy families.
