The lowest acceptable water temperature of Thai lion goldfish is 0 ℃, and they can grow in the water temperature between 0-38 ℃. Moreover, they have low requirements for the environment, as long as the breeder can ensure that the water temperature in which they live is stable. Although Thai lion goldfish can survive in lower water temperature, breeders should not grow them in too low water temperature. Because the living temperature is too low, their appetite and activity will be affected. If they grow in a low temperature environment for a long time, their resistance and immunity will decline, and eventually they will get sick and die.

The most suitable temperature for Thai lion goldfish to grow is between 20-28 ℃. They are cold water fish, and their requirements for water temperature are not high. When raising artificially, it is only necessary to ensure that the water temperature in which they live is between 20-28 ℃. Although their requirements for water temperature are not high, breeders need to ensure that the water temperature in which they live is stable, and they need to keep warm when the temperature difference between morning and evening is large in autumn and winter. If conditions permit, it is best to install a heating rod to keep the water temperature constant. However, in summer, when the temperature is on the high side, they will also have more discomfort. Breeders need to add ice bags to cool them down, or they can be transferred to air-conditioned rooms.
