. To raise goldfish in winter, we should first raise water, change water too frequently, but ensure water quality and sufficient oxygen in the water. When changing new water, we should choose good water, and tap water should be dried in the sun for 3 days. Change one third of the water each time. When changing the water, the temperature difference should not be too large. If the water is too cold, a heating rod should be installed in the cylinder.
In winter, we can reduce the frequency and amount of feeding, because the digestive system of goldfish is weaker in winter. You can choose millet, sesame, fish, earthworm and so on. The water temperature should also be maintained and the heating rod should be used in time to prevent the bacteria from infecting the fish.
in winter in the north? 1. The temperature in winter in the north is relatively low, so we should pay attention to keeping goldfish warm. The water temperature should be kept above 10 ℃. You can move the fish tank indoors or cover it with insulation film. Because the water temperature is too low, the goldfish will stop growing and the color will be dim.
2. Fish tanks should often be exposed to the sun, which can warm the water and sterilize the goldfish through ultraviolet rays. Goldfish are social animals, it is best to feed more goldfish in the fish tank, but under the premise of sufficient space in the fish tank.
3. Northern winter feeding adheres to the principle of a small number of meals, because in the low temperature season, the activity of goldfish will be reduced, and the food needed is not much. You can feed the food once every two days. When feeding, you should observe whether the food is finished. If not, you should fish out the remaining food in time. It is recommended to feed the goldfish at 7-8 am or around 3 pm.
