The best for Brazilian tortoises to be raised with tap water. Both river water and rain water may be polluted, and tap water is relatively cleanest after disinfection, but the only problem is that residual chlorine remains in water, which may affect turtle skin, so it needs to be dried. In order to ensure the turtle's health, it should be changed regularly, and at the same time, attention should be paid to controlling the water temperature to avoid large changes in temperature.

1. Pay attention to temperature difference: When changing water, Brazilian tortoises should first pay attention to temperature difference. Although they have lower requirements for the environment and strong adaptability, too large temperature difference will also affect their lives, and they are prone to catch colds. Therefore, when changing water, breeders need to keep the temperature difference between new water and old water between 3-5 ℃.

2. Pay attention to water quality: Secondly, pay attention to changing water. Most of the Brazilian tortoises are raised with tap water. Because this kind of water is easy to obtain and the water quality is clean. However, tap water is chemically disinfected, which contains more chemicals. Although it is harmless to human body, it has certain influence on Brazilian tortoises. Breeders need to take out tap water or expose it to the sun for 2 days, and then use it best for Brazilian tortoises.

3. Pay attention to the amount of water changed: Finally, the amount of water changed by Brazilian tortoises should not be too large, otherwise the fluctuation of water quality will make them uncomfortable. Therefore, breeders change up to half of the water when changing water.
