Do you need a heating rod for fighting fish?

The suitable water temperature for fighting fish is 24-27℃, so when the temperature can't reach this range, a heating rod is still needed to raise the temperature.

If the breeder raises China betta, he can choose not to use the heating rod. Because of its strong adaptability to the environment and wide range of acceptable water temperature, China Betta can grow in water temperature above 6℃ as long as it can keep the environment stable. Therefore, even if the breeder does not install heating rods for them, it will not affect their lives. But when the temperature is low in winter, the breeder had better put heating rods on them, so that they can live more comfortably. If the breeder raises Thai betta fish, they should be equipped with heating rods. Because fighting fish in Thailand requires high water temperature, the acceptable temperature range is relatively wide. If the breeder does not install a heating rod, it is easy to freeze to death.
