Piranhas were first introduced to China as ornamental fish. Their gorgeous appearance, especially their resounding reputation, are attractive to some fish lovers with a curious mind. Piranhas in natural water bodies are almost always pets or commodities abandoned by owners and traders.

As a tropical fish, piranhas have rigid requirements for water temperature. The climate of the southern part of our country, especially the Liangguang region, is similar to that of its place of origin, which makes it possible for piranhas to survive. Piranhas are highly reproductive, and can lay hundreds or even thousands of eggs at a time.
