Can you turn off a heating light for a tortoise at night?

Yes, you can turn off a heating light for a tortoise at night, but it's essential to ensure they have an appropriate temperature gradient in their habitat. Tortoises require a warm basking area during the day, but at night, they can tolerate cooler temperatures as long as they are not exposed to extreme cold. Providing a nighttime temperature that mimics their natural environment is crucial for their health. Always monitor their behavior and health to ensure they are comfortable.
