The suitable temperature for Thai betta fish is between 22-24 ℃, because they are tropical fish and like higher water temperature. During artificial breeding, it is necessary to keep the water temperature above 20 ℃ according to a heating rod. This can not only ensure that their living environment is comfortable, but also ensure that the living water temperature is constant.

If they live in low water temperature, they are prone to get sick. When they grow in a low temperature environment for a long time, they may not be able to reproduce. In addition, although they are tropical fish, they can't grow in too high water temperature, otherwise they are likely to deteriorate or die.

Thai betta has strong adaptability to water quality, and can grow in neutral, weak acid and weak alkaline water. As long as the breeder keeps the PH value between 6.5 and 7.2, they can grow well.

The pollution of Thai betta fish to water quality is not serious. Breeders only need to change water every 7 days, and the amount of water change each time is controlled at one third of the total water quantity. However, when changing water, we should pay attention to the fact that the water quality between new water and old water should not change too much. Also avoid the temperature difference between new water and old water not exceeding 2 ℃. If conditions permit, a circulating filtration system can be installed to slow down the deterioration of water quality.
