She seems to be acting normal recently: sleep all day, come out at night. She still goes up to the top of the tank at night as if she's trying to escape, but I'm not sure if that's normal or not.
I guess I'll have to see this Friday if she eats. If not, I may have to downgrade.

The thing about a 20g is that my current stuff would barely fit in there. My two hides would take up pretty much the whole tank.

To Calift: I have three thermometers; one for each hide and one for the ambient/humidity that the lock is blocking.
