The requirements of guppies on water temperature are not high. When the room temperature is above 15 ℃, guppies can survive normally, and their lives will not be affected without turning on the heating rods at this time. Although they are tropical fish, they have strong adaptability to water temperature. As long as the water temperature can be kept above 10 ℃, they can survive normally. Therefore, if the room temperature at which they are raised is kept above 15 ℃, they can grow well. Although they can accept a wide range of temperatures, if breeders want them to grow better and faster, they'd better turn on the heating rod and keep the water temperature between 22-24 ℃. In this way, their growth state and speed are the best.

Guppies can install oxygen pumps or not, because their demand for oxygen is not large. If the water in which they are raised is large, the oxygen in the water is enough for them to absorb. At this time, they are not equipped with oxygen pumps, which will not affect their health.

If the feeding density is too high, it is recommended to install an oxygen pump, which can ensure sufficient oxygen in the water where they live. However, the time of oxygenation should not be too long, and it can be done for 3-4 hours every day. In addition, when the temperature is on the high side and the air pressure is low, the oxygen in the water will decrease sharply, and the breeder also needs to give them oxygen at this time.
