It takes 3-4 years for Brazilian tortoises to grow to 15 cm, and their growth rate is relatively fast compared with other tortoises. Under normal breeding, they can grow by about 5 cm a year, so Brazilian tortoises with 15 cm are about 3-4 years old.

Of course, not all Brazilian tortoises grow at the same speed. Different living environments and different foods will affect their growth and development. If properly raised, they can grow to 15 cm in three years. If the Brazilian tortoise lives in a poor environment, it will grow slowly, so it will take longer to grow to 15 cm.

Under normal feeding conditions, the body length of the Brazilian tortoise in adulthood is about 20-30 cm. How big it can grow depends on the feeding environment and feeding method. Although Brazilian tortoises are small in size, their activity is relatively high, so breeders need to prepare a larger container for them to ensure that they have sufficient living space. Only when there is enough living space can their bodies develop bigger.

If the environment for raising Brazilian tortoises is poor and there is not enough food and space, then their body size will develop smaller, and some even grow less than 20 cm.
