in cold water? Bettas can't spend the winter in cold water, because bettas mainly live in tropical or subtropical waters, and they prefer warm water temperatures. The optimum temperature is between 25 and 27 degrees. Although they have the ability to withstand cold, if the water temperature is too low, they will die. Therefore, if the room temperature is low in winter, it is better to use a heating rod to raise the fighting fish. When changing water, the temperature difference should not be too large. If the temperature difference is too large, it is easy to cause the fighting fish to catch a cold. The amount of water change does not need to be too much, about one third of it.
should betta fish pay attention to in winter? 1. Water temperature: Betta fish is a tropical fish, and the water temperature required is 25-27 degrees. During winter, attention should be paid to the water temperature not being too low, and the water should not be changed too frequently. If the water temperature is too low, it will lead to their poor growth and development.
2. Feeding: The amount of feeding in winter does not need to be too much, only one third of the usual amount. If the betta doesn't eat, it doesn't have to be fed.
3. Circulatory system: In winter, the circulatory system can not be opened in the tank of betta fish, because betta fish like quiet and are easily frightened. The water flow of the circulatory system may cause them to be nervous, especially in winter, their metabolism is slow, in fact, they do not need to be opened all the time.
