? Water quality is very important for the breeding of small goldfish. When there is no filtration system and oxygen, it is particularly important to change the water. Generally speaking, the water temperature is high in summer, and the water quality is more likely to change. At this time, the water needs to be changed relatively frequently, and it is more appropriate to change the water once every three days or so. In winter, the water temperature is low, the water quality changes slowly, and the water change time can be extended to about 7 days.
When changing water for small goldfish, we must pay attention not to change too much water at a time, about one third of the water can be changed each time. When changing water, the water temperature should be kept consistent as far as possible. The change of water temperature caused by changing water will seriously affect the health of goldfish. If tap water is used, it must be dried for a period of time before changing the water.
little goldfish is very good. In the first three days after birth, the little goldfish can survive on the nutrition of the yolk. After that, you can feed egg yolk water, not too much. When it comes to normal feeding, it is possible to feed once or twice a day, which is not very important. It's better to feed regularly and quantitatively, not too much at a time. Regular and quantitative feeding can ensure that goldfish can eat up the food every time, and will not affect the water quality because of food residues, so that they can better grasp the time of changing water.
