The body length of domestic snapping turtles in adulthood is between 38-66 cm, but how big they can grow depends on the way they are raised and the living space. If breeders can take good care of them and ensure that their food and nutrition are sufficient, they should be prepared with a larger living environment, so that their body size will grow bigger, which can be about 60 cm. If the breeding environment does not meet their requirements and there is not enough space, they can grow up to about 40-50 cm in adulthood. There are also some Buddha crocodile turtles, which can't reach 40 cm in length even after adulthood.

1. There is plenty of space: The body length of snapping turtles in adulthood is between 40-70 cm. If breeders want to make them grow bigger, they should prepare a large enough container for them to move normally. If conditions permit, it is best to prepare a container 2-3 times larger than their size, so as to ensure sufficient space for their activities.

2. Adequate food: If you want to make snapping turtles grow bigger, you should feed them more nutritious food, so that they can ensure adequate nutrition during their growth and development. At ordinary times, they can be fed more small fish, shrimp, lean meat, animal viscera and so on.

3. Environmental stability: Breeders should ensure that their living environment is stable at ordinary times, which can make them live more comfortably. Although they are not sensitive to environmental changes, we should pay attention to the fact that the water temperature and water quality should not change too much.
