I am new to rescuing a Russian tortoise. I currently have a basking light and a coil uv light. Lately he is just staying in his hut and not coming out to eat. I was looking at switching to a mvb to see if that helped since so many people recommend it. I know they are more expensive so a friend told me that lowes sells mvb lights. I didn't know if those would be ok to use since they were cheaper. Also any other ideas on why she would not come out and eat?
