Pearl goldfish is a kind of fish that is not easy to raise. Because its body shape is round and fat, its stature is relatively small, and it can not adapt to the strong flow of water. Moreover, it is very sensitive to changes in water temperature, if the water temperature changes too much, it will cause discomfort, frequent water changes will also cause it to get sick. In addition, its own constitution is relatively poor, and it is easy to get sick. Therefore, it has a certain degree of difficulty in raising, and it is not recommended to raise new hands.
1. Feeding: Live bait such as earthworms or green worms should be used. This kind of feed has high nutritional value and can better meet their growth needs. Feeding can be 2-3 times a day, but the feed can not be too much at a time.
2. Water environment: Pearl goldfish should be kept in shallow water. Because they are fat and can't withstand the high pressure of deep water. Moreover, they cannot adapt to more mobile water, so clean water should be used for aquaculture.
3. Water temperature: Although they can grow in water of 0-30 ℃, once the water temperature changes greatly, they will grow poorly. Therefore, attention should be paid to maintaining stable water temperature in aquaculture.
4. Change the water: Do not change the water too frequently. Change the water once a week. When you change the water, you don't have to change it all, about a third or a quarter.
5. Breeding density: The breeding density should not be too dense, otherwise the phenomenon of insufficient oxygen will occur.
