Yeah, I thought it was the saliva's properties that softened the cap enough to pop back. If that were so then the information might have helped someone but being that is not the case I feel a little silly. Oops...it happens
Here is a pic of Soku's habitat. I plan on darkening 3 sides but I'm afraid of causing too much change at once for the little guy so I am going to wait a week or 2.
I am also going to get a digital thermostat and hydrometer but for now I am using a digital for temps every day. I am now using a heating pad which on medium setting is staying a steady 93-94 degrees on the warm side and around 80 on the cool side. I have 2 humidity gauges that read about 10 degrees different. The high has been a steady 60 and lower reading gauge 50.
Thanks again for all of the advice.
