The betta is a tropical fish, not a cold-water fish. It is mainly distributed in tropical and subtropical waters, and also in China. It likes to live in warm water, if the water temperature is too low, it will lead to poor growth, a variety of growth problems.
Bettas like to live in warm waters between 25-28 degrees Celsius. If the water temperature is below 20 C, it is easy to grow poorly. Therefore, when maintaining it in winter, we should pay attention to keeping it warm. If the water temperature in the room is too low, you can put a heating rod in the fish tank to maintain the water temperature. In addition, when changing water, do not change all, generally change one third or one half of the water can be. This is to ensure that the water temperature will not drop sharply, so as to avoid the problem of poor growth.
Whether they need to use heating rods when breeding betta fish depends mainly on whether the environment for breeding it is cold or not. If in the north, the temperature is very low in winter, it is better to prepare a heating rod in the fish tank. Warm the water when it's cold to keep the betta from freezing. If you are in the south, and you can keep the place where you breed betta fish warm all the time, you can do without heating rods. It should be noted that there are also cold places in winter in the southern region. Heating rods are also recommended when raising betta fish in these areas.
