I am not home all day. My wife is home while I work and I'm home while she is at work, but I have a Hygrotherm unit made by Zoo Med. it does have a Reptifogger hooked up to it that the unit turns on when humidity drops below 80%. so my climate stays consistent which is very important. Ambient air humidity is just as important as moist substrate. if the soil is moist, but the air isn't then they will burrow so that they can retain moisture. it can make them lathargic from being full of water from the substrate. Not feeling comfortable when above ground is also stressful. I'm almost certain that she is burrow down all the way due to ambient air humidity lacking enough moisture. I see my Pacman Frogs do this all the time., but without lathargy and appetite loss.

I believe this is causing stress which is why your frog lacks an appetite.

You might want to invest in a Zoo Med Hygrotherm and a Zoo Med Reptifogger to help maintain your Eric's climate. It's a good investment.
