He has two hides, one on each side, one made of rock that is real snug, and one small log on the other that is only open on one end. I will see about keeping the consistant temperature thru day and night, is 85F ok? Also I am using a digi hygrom/thermo so i know those readings are accurate. He is in a 20" x 10" glass tank so I dont think that the size is an issue. Thanks to all who posted so quickly, please keep the suggestions coming. Thanxx again
