in winter? Chinese bettas are mainly distributed in subtropical areas. Although they are most suitable for growing in warm environments, they can survive in low temperatures. During the curing period, the optimum growth temperature is between 25 and 28 deg C. Because the Chinese fighting fish has a strong constitution and strong adaptability to the environment, it is easy to maintain, it can tolerate the low temperature environment above 0 C, even if the aquarium is not heated in winter, it will not be easily frozen to death. Under the condition of artificial breeding, the water temperature can be adjusted between 26 and 27 degrees Celsius, but the water temperature should be kept at 28 degrees Celsius during the breeding period.
Chinese betta has no special requirements for temperature, and its low temperature resistance is strong. In winter, as long as the water temperature is not lower than 3 C, it does not need to be heated. When the temperature in the water tank can not meet their growth needs in winter, the water tank needs to be heated at this time. The water temperature can be adjusted to about 26 ℃ by using a heating rod, and the activity of the betta can be observed to see if there is any abnormal situation.
In addition, if it is maintained indoors and there is heating in the house, it is basically unnecessary to heat it in winter.
