Your temp are a little cold, and temperature is the most important thing in keeping a tortoise healthy. Please read through this entire thread. It should help you quite a bit. Have you tried baby food soaks? Just mix carrot baby food 50-50 with nice warm water and soak the tortoises in that for AT LEAST 15 mins twice a day, even if they try to get out. The baby food and the water will soak up in to their body and they will get some vital nutrients and energy. Just make sure that is high enough so it comes up just passed the bottom of their shell.
