guppies need to be heated in winter because they are tropical fish, and their origin is Venezuela, Guyana and the Caribbean. The temperature in their place of origin is on the high side, and even in winter, the temperature will not be too low. However, the temperature in China is relatively low, and most areas cannot reach the temperature of their origin. Therefore, in winter, if the guppy is not heated, it may freeze to death. It is best for breeders to install a heating rod to keep the water temperature in a stable range. In addition, if breeders can transfer them to warm rooms, they can not be heated in winter.

1. Water temperature: After entering winter, breeders need to keep the water temperature of guppies above 20 ℃. This can not only ensure their living environment is comfortable, but also ensure constant temperature.

2. Change water: In winter, the frequency of changing water should also be reduced. Because guppy pollution to water quality will be reduced in winter, breeders only need to change water once a week. The amount of water changed each time should not be too large, and it should be controlled at one third of the total amount of water. If the filter is installed, the water can also be changed once every 2 weeks or so.

3. Feeding: Guppies lose their appetite in winter. Breeders need to reduce the amount and frequency of feeding, which can not only reduce indigestion, but also maintain adequate nutrition.
