1. Changing water: When raising goldfish in winter, we should also pay attention to the water quality. That is to say, regular water change is also needed. However, the winter water can not be too frequent, generally speaking, control in a week or two to change once on the line. Do not change the amount of water too much each time, about one fifth is better, do not let the water environment change dramatically. If there are impurities such as feces in the water, you can use filters and other tools to remove them.
2. Water temperature: It is a very important choice to ensure that the water temperature is suitable for breeding goldfish in winter. In winter, fish tanks should be placed indoors as far as possible, not outdoors. Generally speaking, if there is heating in the room, the water temperature is generally OK. In the case of very low water temperature, heating rods and other tools can be used appropriately.
3. Feeding: In winter, with the decrease of water temperature, it is necessary to reduce the amount of feeding for goldfish. However, as long as the water temperature is not too low, we still need to continue feeding. It can be fed only once a day, and the amount of feeding should be reduced. In winter, the activity of goldfish will be relatively low, not very active, feeding too much can easily lead to poor digestion.
4. Disease prevention: In winter, it is also necessary to prevent goldfish diseases. Generally speaking, in order to disinfect and sterilize, a part of salt can be added to water.
In winter, if the water temperature is relatively low, you can feed them every few days. If the water temperature is suitable, you need to continue to feed regularly, once a day is better. However, compared with other seasons, the amount of feeding should not be too much.
