It is not necessary to use oxygen pump to raise goldfish, but it is best to decide whether to use oxygen pump according to the number of people raised. Under normal circumstances, as long as the number of fish in the fish tank is small and there is plenty of living space, it is ok for the breeder not to give them oxygen. Because goldfish's demand for oxygen is not high, as long as the breeder can keep a stable frequency of changing water, the oxygen in the new water is enough for them to absorb. However, if there are a large number of fish in the fish tank or the fish tank is too small, the breeder needs to give them oxygen, so as to ensure sufficient oxygen in the fish tank. However, the time of oxygenation should not be too long, and it can be done for about 2-3 hours a day.

1. Environment is stable: goldfish have low requirements for environment, but they are sensitive to environmental changes. Breeders need to keep their living environment stable so as not to make goldfish uncomfortable.

2. Reasonable feeding: Goldfish eat a lot, but they don't feel full. Breeders need to feed them regularly and quantitatively, which can not only ensure their adequate nutrition, but also reduce the occurrence of indigestion.

3. Proper lighting: Breeders should also give them regular sunshine, which can increase their body color, improve their resistance and immunity, and make them stronger.
