1. Comfortable water temperature: guppies are tropical fish and like higher water temperature. However, the temperature in winter in China is relatively low, so breeders need to keep the water temperature above 18 ℃. If conditions permit, it is best to install a heating rod to keep the water temperature in a suitable range.

2. Change water properly: Guppies do not pollute water quality seriously, especially in winter, their metabolism will become lower. At this time, the amount and frequency of changing water for them by breeders should not be too high, and it is OK to change water once every 5-7 days. If conditions permit, it is best to install a filter, and the frequency of changing water can be lower.

3. Adequate sunshine: If guppies want to spend the winter better, the breeder had better expose them to the sun for about 2 hours every day. Adequate sunlight can not only speed up their growth, but also enhance their resistance and immunity.

After entering winter, guppies' appetite will decrease. Even if the breeder can keep their water temperature constant, their appetite will be affected to some extent. Breeders should pay attention not to feed too much to avoid indigestion. Under normal circumstances, the breeder feeds once every 1-2 days, and the amount of each feeding can be finished within 3-5 minutes. If they don't eat well, the breeder can also feed them once every 2-3 days instead.
