To prevent your turtle's shell from becoming soft, you should ensure that they have a balanced diet that includes calcium and vitamin D3, as these are essential for shell health. Providing a proper basking spot with UVB light will also help your turtle absorb calcium and maintain a healthy shell. Additionally, keeping the water in their habitat clean and at the right temperature will promote overall health and shell strength. Regular veterinary check-ups can also help catch any issues early on.
