I kept mine around 80F and misted them when they were in shed. These guys were in large plastic tubs so humidity wasn't too low at other times. They require quite a bit of room and are very aggressive, but fun to handle (if you have the nerves!). They will eat you out of house & home. I never had success breeding them though.
