The best water temperature for Thai betta fish is 22-24 ℃, because they are tropical fish, and the temperature in their place of origin is on the high side, so the living water temperature is also on the high side. In this temperature range, their appetite and activity are the highest, and their growth speed is also the fastest. Although they prefer a little higher water temperature, breeders can't raise them with extremely high water temperature. Because high temperature may cause them to have decreased resistance and deteriorate their physique.

In addition, the water temperature should not be too low, otherwise they may have loss of appetite and decreased activity. When raising artificially, you can choose to install a heating rod to keep the water temperature between 22-24 ℃.

1. Keep the water temperature: The origin of Thai betta is in Thailand, and the temperature in Thailand will not be very low in winter. However, the temperature in most areas of China is relatively low in winter, so breeders need to pay attention to the water temperature in the fish tank when breeding. If conditions permit, Thai betta fish can be placed in a warm room, and if the indoor temperature cannot be guaranteed, a heating rod can be installed in the container.

2. Reduce water change: When the temperature is lower in winter, the metabolic speed of Thai betta fish will also decrease. Breeders can choose to reduce the frequency of water change and change water every 2-3 weeks instead. When changing water, we should also pay attention to the temperature difference between new water and old water, otherwise it may cause them to have stress reaction.
