What kind of fish is suitable for raising fish by ancient methods?

The expert replied that the ancient method of raising fish is most suitable for goldfish and koi fish, because goldfish and koi fish have thicker skins, are less difficult to raise and can adapt to the outdoor environment.

Goldfish swim slowly, and some species are very suitable for keeping in ceramic tanks, such as Lanshou Goldfish, Heding Red Goldfish and Lion Head.

Koi fish is suitable for overlooking and viewing, but they are large in size and have certain requirements for space. Therefore, it is necessary to use relatively large containers when farming by the ancient method.

Traditional fish tanks are mainly used in ancient fish culture and are usually made of stones, pottery, sand, porcelain and other materials. Traditional fish farming is generally outdoors, and some aquatic plants such as aquatic plants and duckweeds will be planted in the fish tank, which can make them form a good ecological cycle and make the fish grow healthier.

The biggest feature of ancient fish farming is that there is no electric equipment, such as heating rods, filters and oxygen pumps. So most fish tanks should be buried in the soil so that the water temperature can remain stable.
