2. Solution: The breeder needs to raise the water temperature to 22-24 ℃ immediately, and use a heating rod to keep the water temperature in this stable range. Especially in autumn and winter, the temperature difference between morning and evening is large. If the temperature is too low, their living conditions will get better.
