Chinese betta fish can tolerate lower water temperature. Under normal feeding conditions, as long as the water temperature can be kept above 3 ℃, they can live normally. But when raising them artificially, try not to raise them at too low water temperature. Because they are mainly distributed in the south of China, they prefer to grow in warm environment. If breeders breed them in a low temperature environment, their growth and development will be affected to some extent. If they live in a low temperature environment for a long time, their resistance and immunity will also decline, their physique will become worse and worse, and eventually they will die.

Chinese betta fish are mainly distributed in subtropical zone, so their favorite water temperature is also on the high side. During artificial breeding, the water temperature can be kept between 25-28 ℃. In this temperature range, their appetite and activity are the highest. Moreover, they grow in the best state. As long as the temperature is stable, they generally do not get sick.

In addition, Chinese betta fish has strong cold resistance, and can grow in the water temperature between 3-30 ℃. When artificially cultured, they can survive normally as long as the water temperature in which they live is constant. Although Chinese betta fish can survive without heating, if breeders want them to grow better, they'd better use heating rods to keep the water temperature constant.
