Bearded dragon - sick?

Question
My dragon has been curling up in the corner of his tank more often lately.  We lost power twice recently... He was without heat for a few hours before I could get to the school to rescue him... Is he sick? Another teacher recently lost an iguana, and she said hers was sleeping a lot before it died... I don't want to lose this little guy! :(

Answer
Hello, bearded dragons can survive with heat through the low 60's. If it was any lower then that he may be in trouble. The body needs a high amount of heat to digest food and to run properly. Make sure he is getting all the heat he can now and if there is no change contact a vet.
