Hello, I wanna get a Russian Tortoise, to convince my parents that I am able to care for a animal I am doing research on Russian tortoises. One thing that I am confused about is what type of lights or light should I get? I hear that a Mercury Vapor Bulb (MVB) works the best, if so then do I still need a Ultraviolet Bulb (UVB) and Heating Bulb (HB) or can I just get a MVB? Please help I really want a tortoise!
