Hi my Greek tortoise, Sheldon is not moving. He hasn't moved for the past three days and today I picked him up to see if he was okay. He has been next to his rock by the basking lamp and when I picked him up I noticed his eyes weren't open and his legs felt very stiff. I then filled his water dish warm water and briefly soaked him before putting him under the basking lamp. As I i setting him down I noticed his back right leg was very limp. Please help I haven't had Shelly for very long and he's only about 5 years old.
