Many people don't know that the family goldfish actually originated in China. As early as the Song Dynasty in the 12th century, we began to study the domestication of goldfish. After such a long time of development, the variety of goldfish has been greatly optimized. Now, goldfish in the world are introduced directly or indirectly from China. Chinese goldfish, which has accompanied human life for more than ten centuries, is the earliest species in the history of ornamental fish in the world. How can we raise goldfish to survive more easily?

First of all, we need to pay attention to some details when choosing goldfish in the market. We should choose the fish with strong body and bright colors. The fish with broad body, complete chest, abdomen and tail fins and open tail are the best. When selecting some species without dorsal fin, we should select the fish with smooth back and without incomplete dorsal fin or nodule. Fish that are active, gregarious, full-bodied, without white spots and fluffy mucus on their bodies, without bloodshot and festering on their tails and scales indicate that they have no disease. Such fish should be the first choice. All kinds of fish have their own characteristics: longevity head, lion head, heding red, goose head red and so on. Such fish have good ornamental value and should also be included in the purchase list.

Secondly, the quality of the fish tank is a key factor for the survival of the fish. The quality of the fish tank here does not only refer to the firmness of the tank, but also includes the size of the opening, whether it contains harmful substances and whether it is easy to clean. The basic requirements of the fish tank are firm, durable, water tight, free of harmful substances, small dead angle, high flatness and wide mouth as far as possible.

Finally, it is also the most critical feed problem. Goldfish is best fed with live bait, which is good for the micro ecological environment of the whole bathtub. There are fish worms (also known as red insects, water fleas), Cyclops (commonly known as green skipping), Paramecium (commonly known as grey water), larvae (mosquito larvae) and so on.
