If the breeder breeds Chinese betta fish, he can choose not to use heating rods. Because Chinese betta fish have strong adaptability to the environment and a wide range of acceptable water temperatures, they can grow at a water temperature above 6 ℃ as long as the environment can be kept stable. Therefore, even if the breeder does not install heating rods on them, it will not affect their lives. But in winter, when the temperature is low, it is better for breeders to install heating rods to make their lives more comfortable.

If the breeder breeds Thai betta fish, it is necessary to install a heating rod for them. Because Thai betta fish has high requirements for water temperature, and the acceptable temperature range is relatively wide. If the breeder does not install heating rods on them, it is easy to freeze to death.

In general, betta fish do not need filters. Because betta fish are aggressive by nature, the density of breeding is generally not very high, and their pollution to water quality is not serious, so it is ok not to install filters.

In addition, betta fish like to live in still water, and installing filters will affect their normal life. Moreover, it will affect their normal rest at night. As long as the water quality does not deteriorate rapidly, breeders do not need to install filters for them.
