1. Clean water quality: If you want goldfish to live for a long time, you need to keep the water quality clean. When changing water for them, the chlorine gas in the fish tank should be cleaned up to avoid too much impact on their health.

2. Constant water temperature: Goldfish have low requirements for water temperature and can adapt to a wide range of temperatures. As long as breeders keep the water temperature in which they live constant, their health will not be affected.

3. Regular disinfection: Breeders should also check their bodies regularly, so that diseases can be found in time. It is also necessary to sterilize them regularly, so as to reduce their chances of getting sick and avoid getting sick. Because illness can affect their longevity, reducing illness can appropriately prolong their longevity.

1. Feed reasonably: If breeders want goldfish to grow faster, they should be fed more high-nutrition foods. This will not only ensure that they grow faster, but also make their physique stronger. However, don't feed the same food for a long time, which will easily lead to single eating habits and single nutrition.

2. Comfortable environment: If you want goldfish to grow fast, you should prepare a comfortable living environment for them. Because the environment is comfortable, they grow in the best state, so the growth speed is also the fastest.
