My yung pacman frog haven't eaten for over a week

Pedialyte is an oral electrolyte solution for infants and children that helps prevent dehydration by replenishing vital minerals lost during diarrhea and vomiting. If Revolyt is the same and unflavored, it should be OK. Just follow Lija's instructions for soak. Noted the grasshopper in pic is a bit big for frog size (length should be around distance between eyes). Good luck !

yeah, it seems Revolyt is the one, i tried to google it but it came back not in English but go ahead if it is unflavoured and without any dyes, it should be clear solution, like water.
instead of dubia i would better do piece of nightcrawler coated with reptiboost, nightcrawler or earthworm is easier to digest then anything else, after not eating for so long it's better not to overload digestive system, but small dubia is fine too.

you said he is not eating, would you please describe how you were trying to feed him as well as what time a day, what food and where. how long has he been in his new smaller enclosure before you tried to feed him?

and you gotta try to lower humidity some more, you want 75-80, not 80-85.

When i try to feed him, it is usually with tongs, or i just drop the insect in front of him, but he never takes it. The time of day is around 10 pm or when it has been dark for a few hours.
The humidity is kind of hard to get any lower without the surface of the substrate drying completely out.

what size of insect? and what kind of insect? the picture above - does it reflect the size of insect in comparison to the frog?

where are your gauges and what kind are you using?

Sounds like force-feeding is necessary for right now, but if he continues to be a difficult eater, this is something I have found worked on my frog when she had some long-term issues and wasn't eating well, but wasn't bad enough to need force-feeding.
If you get a nightcrawler (cut to the right size) and rub it with light pressure on the frog's lips for a minute, it will often snap out of anger and once it gets started on the worm it will usually finish it. This works good if a frog is unwell for longer periods of time, as it causes less stress than actually force-feeding.

The hopper in the pic is not the size i normally feed him it was the largest in the box.
The dubia and hoppers i tried to feed to him were roughly 1-2cm in length (not longer than the space between hes eyes)

I use a digital termo/hygrometer (TRIXIE Heimtierbedarf GmbH & Co. KG) and the sensors are located in the bottom side of the tank .
