I see many people just copy other people's statements when they answer, and even the basic questions can't be solved. I think guppy and anchovies are exactly the same, and they are probably close relatives, but they are definitely not a kind of fish, and there are no two names for a kind of fish. The differences are as follows: First, anchovies are native fish, which are found from the source sea in China to the northeast to the South China Sea, and guppy is an exotic species, native to South America. Second, anchovies are marine fish, and they can also live in fresh water. Peacocks are freshwater fish and cannot live in seawater for a long time. Three anchovies are not pure tropical fish, and most of them can survive in the cold waters of Northeast China, but guppies are absolute tropical fish, and there is a survival crisis when the water temperature is lower than 18. As mentioned above, guppies and anchovies are not a kind of fish. Our families raise them as ornamental fish. In fact, there is no need to raise guppies from South America, and anchovies are more valuable. Among them, anchovies from Wenzhou, Zhejiang Province are delicious and canned and exported overseas.
