Has the goldfish with green skin and blue life been eliminated?

Lanshou is by no means enlarged in equal proportion. It is a fatal mistake to choose the fish of that year according to the miniature version of the 3-year-old fish that has been raised to the extreme. If you just want to keep it for fun, you can choose a medium height, well-developed head and hard tail. That's enough.

However, if you want to spend time and energy to raise the fish of that year. Then it is wrong to choose according to this standard. Lanshou develops in different parts in different months. It is very important to lay the foundation in the early stage. If the skeleton can't be opened in that year, it will only be a small old fish in the next year. Old fish are characterized by bigger eyes, thinner body, dull scales and soft tail. Swimming like a satrap, tail swinging. The texture of the tail becomes very thin, without thickness and hardness. Because the tail is soft, the stress intensity of the tail becomes lower, which leads to the tail pipe becoming thinner and thinner. When not swimming, the body is crooked.
