These are amphibious turtles. Adults can actually live in one meter deep water, but there must be shallow water and land. They breathe with their lungs. In deep water, they have to keep paddling to breathe, which takes a long time. If there is no place to rest, you will be exhausted. Generally, shallow water is enough. If the place is large, prepare deep and shallow water areas, land areas, and basking areas. They will not kill themselves
