Chinese betta do not need to be heated, because they have strong adaptability and can tolerate low temperatures of 6 degrees Celsius. Generally, they do not need to use heating rods. But Thai fighting fish need to be heated, because their favorite water temperature is 25-28 degrees Celsius, although they can tolerate low temperatures, but when the water temperature is below 18 degrees Celsius, there will be a decrease in activity and appetite. Therefore, when raising Thai fighting fish, it is necessary to install heating rods to keep the water temperature constant. When changing water at ordinary times, attention should be paid to controlling the temperature difference between new water and old water within 2 degrees Celsius, so as to avoid the stress reaction of fighting fish caused by excessive temperature difference.
? Bettas need to bask in the sun, because a moderate amount of sunshine can promote the hair color of bettas, enhance their ornamental value, and make them more energetic. Although sunlight is good for bettas, they can't be exposed to light for a long time. Because they like to live in a dark environment, if the light is too strong, they will have discomfort. Therefore, it is best for breeders to give them sunshine at 9-10 A. M. every day, when the sun is not very strong, suitable for bettas to receive light.
