I have a male normal BP he is 7 months old he is shedding today and is doing great with it but I worry that I don't have his tank warm enough the thermo reads 75 and the girl I got him from said that is fine but I still worry. I have over head lights and UTH that sits under his hide that he never goes into he either stays beside his rock water bowl on the cool side or in a planters pot ( Halloween decoration the kids wanted him to have its very small ghost) curled up on the warm side. WHat can I do to get his tank warmer?
