The most suitable temperature for the growth and development of guppies is between 22 and 26 degrees Celsius. However, their adaptability is strong, so they can survive in the temperature range of 20 to 32 degrees Celsius. If the temperature can be maintained in this range, there is no need to use heating rods. If the temperature is lower than 20 C, it will bring different degrees of influence on their growth. If the temperature is between 16 and 20 degrees Celsius, the food intake of fish will decrease, the growth rate will gradually slow down, but they can still survive. If the temperature is lower, when it reaches 13-16 C, the fish will not like to swim and the disease resistance will become worse. At this time, the heating rod should be used immediately to increase the temperature of the fish tank, otherwise once the temperature is below 13 C, it will cause a large number of fish deaths.
The temperature in winter is generally low, especially in the northern region, the temperature drops very fast. When breeding guppies in winter, it is better to control the temperature above 20 C. In this case, even a small drop in temperature will not immediately make it difficult for fish to survive. If the water temperature does not reach 20 C, heating measures should be taken, and heating rods can be used to raise the water temperature. Note that when changing water in winter, the temperature of the new water can not be too low, it is best to adjust to about 20 degrees Celsius, and then pour into the fish tank. This will not cause the temperature of the whole water body to change too much, so as to avoid the discomfort of the fish.
