Pacman strange behavior?

[Erupcion]

I picked up an Albino Pacman just over a month ago and he's been a good eater since the first time as expected but recently he or she's just been burrowing for days at a time coming out only to shed hang out for the night and burrow back down.
This sounds relatively normal but the problem is that he/she hasn't been eating much if not at all just straight up refusing food. Also haven't seen poop in just over 2 weeks but there seems to be no hard lumps or anything that sticks out of the ordinary.The frog has never pooped inside the water dish only peed and bathed in there a small bit. always pooped above ground where I can see it. I don't know if they have pooped underground anywhere I couldn't find anything personally I have Dwarf white isopods in the tank with it but they havent really expanded enough yet to actually clean the tank. I feed small dubia's around 5-6 a feeding dusting (with zoo med repti calcium with d3) once a week and feeding with tongs over top of a small plastic lid to avoid any impaction. I have an Exo-Terra digital thermo/hygrometer that sits just about an inch into the substrate since that's where it's at most of the time and it sits around 85-90% humidity underground. The temperature sits around low 80's high 70's dipping a bit at nighttime. This is in an Exo-Terra 12x12x12. Has been eating the skin as far as I can tell since I never find any of it around the tank (I work nights so I am usually not here at night unless its a weekend but I sometimes catch it outside of its burrows before and after work.) I have included 2 pictures from just these last 2 weeks If anybody can tell me if something is wrong would appreciate anything thanks.

Hi how are you heating the tank? And your humidity needs to come down, 80% is the highest it should be. I personally keep mine at 75% with no problems. If its to high he can get a respiratory infection and this will make him not feel to great.

So far I haven't been which is usually a common issue i've been reading that people have I am going to fix that asap any recommendations on brands for the heating pad? I notice his eco earth gets a tad dry on top. I'm a little worried about the size of the pad i don't think i would want it underneath the entire tank probably just half. It is quite warm where i have him kept at the moment so I don't want it to be too hot. I've been spraying the tank about twice a day thanks for replying.
