We have her in a 30-gallon tank with coconut fiber substrate and a hide on each end. For heating we have a heat lamp and heating pad under the tank. The cool side is usually 75°F and I measure it with a digital thermometer/hygrometer with probes you can stick to the wall. The hot sise upwards of 88°F and just has a digital thermometer leaned up against her hide.
I did read on a couple of websites that handling just before a shed can stress them out, and stress can cause regurge. But that was just a quick googling. It was a week and a half after her last feeding. I don't think she's sick because she's actually been more active than I've seen her in the month since we got her.
