Thai betta fish can live in weak acid, weak base and neutral water, because they have strong adaptability and low requirements for water quality, so they can live normally as long as it is not strong acid or strong alkaline water. The PH value of Thai betta fish can be kept between 6.5 and 7.2. As long as the fluctuation of water quality is not great, they can live normally.

The pollution of Thai betta fish to water quality is not serious. Breeders can change water once a week at ordinary times, and it is best to control one third of the total water quantity every time. When changing water, we should also pay attention to the temperature difference between new water and old water not exceeding 2 ℃, so as to avoid too large a temperature difference affecting their growth and development.

Thai betta fish can live in water temperature between 20-30 ℃, and they can live normally as long as the breeder can ensure the water temperature above 20 ℃. But if breeders want them to grow better, it is best to use heating rods to keep the water temperature between 22-24 ℃. In this temperature range, their appetite and activity are the best, and their growth speed and state are also the best. When the water temperature in which they live is lower than 20 ℃, there will be problems such as decreased activity, loss of appetite and decreased resistance. Some of them will get worse or die gradually.
