The most obvious manifestation of fear in Brazilian tortoises is that they will retract their heads, limbs and tails into their shells and will not come out for a long time. In addition, they will become neurotic. Once someone approaches or there is a loud sound, they will scurry back and forth in the container, and some will remain motionless. They are in a state of fear for a long time, which will also affect their eating. Some tortoises also have refusal to eat and diarrhea, and if they are serious, they will suffer from incontinence. Although Brazilian tortoises have strong adaptability, their long-term unhealthy state will also affect their health and physique. Breeders need to appease them immediately after finding them afraid. If they refuse to eat and have diarrhea, it is recommended to seek medical advice immediately.

Brazilian tortoises are lively and like to interact with people. It is relatively simple to make them not afraid. When feeding, the breeder needs to feed himself. If he has time, he can talk to them and familiarize them with the owner's voice and smell. When they are no longer afraid of their owners, they can feed them with food in their hands, which can make them interact with their owners and form conditioned reflex. When the owner approaches again, they will be extremely excited.
