It is ok for guppies not to use heating rods in spring and summer, because the temperature in spring and summer is generally above 20 ℃, which is more in line with their requirements for water temperature. But in winter, breeders need to install heating rods for them. Because the temperature in winter is low, it is often below 0 ℃. In addition, in winter, the temperature will change greatly. It is difficult for guppies to adapt to the low water temperature and the environment with great changes, so it is necessary to install heating rods to ensure that they can survive the winter normally.

If the breeder can move them to a heated room, the breeder may not install heating rods on them. Because the temperature can reach about 20 ℃ in a heated room. In this environment, guppies can also grow normally.

guppies not install filters, because they are small in size and have a low metabolic rate. As long as the breeder can ensure that the water is changed regularly and no filter is installed, it will not have too much impact on the water quality.

But if conditions permit, it is better for breeders to install filters. Because filters can slow down the deterioration of water quality and reduce the frequency of water change by breeders. This can keep the water quality stable and avoid the impact of water quality fluctuation on their health.
