The foil is a great idea. I'll try that. I've been measuring it with a dvom that I have a temp probe (thermocouple) that I stick in the substrate. It's been better than nothing but I'll be getting something more permanent. There are two of those small heaters. One is right under the tank under the hide and the other one is on the back. I was hoping the one on the back would help a bit with ambient air temp bit it doesn't do much if anything at all. Its definitely a work in progress but I'm confident we're moving in the right direction. I'll go get a thermostat tonight to control everything. I haven't weighed her yet but I'm working on getting a scale. I'm sure the mice are too small but she pounded three of em. I definitely want to get her feeding figured out but decided to wait since she's had absolutely everything changed this week. Seems to be handling everything extremely well though. It's almost like she can tell I'm trying to help her out.
