Salmon (red wen-yu)
The original name striped fish, as early as the end of the Ming Dynasty, when the goldfish was raised by the pond into the basin and tank, the color of the goldfish gradually increased. In order to distinguish it from the original goldfish, it was called "striped fish" with the meaning of pattern on its body. This is recorded in the rest of Kao Bo in the Ming Dynasty. It is characterized by a short, wide, triangular body with a pointed head like a mouse's head; it is the earliest species in the language with well-developed fins, which evolved directly from grass goldfish. Japanese red gold, which comes from Chinese red fish, was originally only red, but it has been cultivated year by year with more colors and richer varieties.
