So I just got my need about a week ago. Eats well, has good weight, but won't go to warm side of tank. Made sure temps and humidity was up to par before trying other things. Ambient temp is 85 with basking spot of 90. Cold side is 76 to 79 tops. He just refuses to go on the warm side. Tried switching the hides around to see if he liked one hide better then the other. Got identical hides to try out. Made sure that he doesn't have direct contact with heat pad. All heat elements are control by temp controllers. Maybe he's just a cold side of bp. Lol. What do u guys think.
