It is most suitable to control the temperature of Mickey fish at about 22-26 ℃, but their requirements for water temperature are not high, and they can accept the water temperature between 18-30 ℃. Although they can accept high or low water temperatures, breeders are not recommended to breed them at too high or too low water temperatures. Because the water temperature is high or low, it will affect their health and their physique.

For cultured Mickey fish, the water temperature can be kept between 22-26 ℃. This can not only ensure their activity, but also avoid their discomfort caused by too large temperature difference.

Whether Mickey fish can live without heating depends on the season in which they live. If it is spring and summer, they can survive without heating. As mentioned above, they can adapt to a wide range of water temperatures, and the natural temperatures in spring and summer are within their acceptable range, so it is ok not to heat them.

In autumn and winter, it is possible to freeze to death without heating. Because not only the temperature is low in autumn and winter, but also the temperature difference between morning and evening is relatively large. If breeders don't install heating rods to keep them warm, they will easily freeze to death. Even if they don't freeze to death, the temperature difference is too large, which will affect their health. In addition, although the temperature is comfortable in spring and summer, it is recommended that breeders turn on the heating rod at night, so as to avoid discomfort caused by temperature difference.
