10 cm Brazilian tortoises are generally around 4-8 years old, and the specific age depends on their living environment. Under normal circumstances, Brazilian tortoises raised at constant temperature grow the fastest, and they only need 3 years to grow to 10 cm. Because keeping them at constant temperature eliminates hibernation time, and the environment is more stable, which is more conducive to their growth.

If it is a domestic Brazilian tortoise, it usually takes only 4-5 years to grow to 10 cm. Because the Brazilian tortoise raised in the family has enough food and the living environment is relatively good, the growth and development speed is relatively fast.

If it is a wild Brazilian tortoise, it takes 8 years to grow to 10 cm. Because the wild environment is poor, and food and nutrition are not sufficient, the growth rate will be slower.

Brazilian tortoises generally mature in about 5 years, at which time breeders can let them reproduce. If the breeding environment is better and the food and nutrition are sufficient, the time for their development and maturity will be shorter. If the breeding environment is poor, they will grow up slower. Although Brazilian tortoises can mature in about 5 years, their body size will grow slowly, and they will stop growing only after 7-8 years of birth.
