Thailand fighting fish is not cold water fish, but tropical fish, like the water temperature is 22-24 ℃. They are native to Thailand, which has a tropical monsoon climate, so they are tropical fish, not cold-water fish.
Thailand fighting fish must not be raised in cold water. The lowest water temperature they can withstand is 20 degrees Celsius. If the water temperature is lower, their growth rate will be significantly reduced, and their vitality will be much less than before. In addition, the resistance of Thai fighting fish growing in low temperature water for a long time will also decrease a lot, and it is easy to get sick and die. Therefore, when breeding them, we must not use cold water, but use water with temperature between 22-24 degrees Celsius.
In the winter, we must do a good job for Thailand fighting fish insulation work. The first thing to do is to put the fish tank in a warm room, preferably a heated room. When changing water, special attention should also be paid to not pouring the cold water just received directly into the fish tank, otherwise the water temperature in the fish tank will drop and the fish will be uncomfortable. Should receive water first come out, bask in below the sun 1-2 days, when water temperature rises, pour water into crock in. In addition, if you are still worried, you can install a heating rod in the fish tank to keep the water temperature and prevent them from freezing.
