The water temperature suitable for the growth of Thai fighting fish is between 22-24 degrees Celsius. It is a tropical fish, and if the water temperature is very low, it will grow poorly. Thai fighting fish living in water below 20 C for a long time will have a significant decline in vitality and resistance, and will easily suffer from enteritis or some other diseases. In addition, if the water temperature is very low, they will not be able to reproduce.
1. Keep warm: The biggest difficulty for Thai betta fish to survive the winter is to control and maintain the water temperature. Because the temperature in winter is relatively low, the water temperature will also drop. If the decline is severe, the fish will not be able to adapt and have growth problems. Therefore, when breeding, attention should be paid to keeping warm. It's best to keep the tank in a warm room. If the weather is cold in the north, it is necessary to install a heating rod in the fish tank in winter to keep the water temperature.
2. Reduce water changes: In winter, it is necessary to reduce the frequency of water changes for fish. Usually about a week for a time, then the winter time to change every 2-3 weeks for a time on it. You don't have to change all the water every time you change it, just about a third of it. When changing water, we should pay attention not to add new water with too low temperature to the fish tank. If cold water is added directly, the water temperature in the fish tank will drop sharply, which will easily lead to fish illness. If you use tap water, it is best to put it in the sun for a few days, and then change it after its temperature rises.
