juvenile pacman hasnt eaten in week or so

[SmallAmphibian]

When I bought him 3 weeks or so ago he ate every day for two weeks even his first day in his tank. Now he has gone a week without eating and I can see his back/hip bones

I heard these frogs hibernate during winter, he constantly burrows so now I nidge him out and try feeding every other day but he just isnt eating. He is about 2.5 inches long

Hes in a 5 gallon. I wanted to update to a 10 gal I tried buying on Amazon but the seller is pathetic and hasnt even begun shipping which I bought a whole month ago.

Temps are 80 at day, 72 at night. Humidity at a constant 70-80%.

Daughter would be sad if he passes. Although I would buy another and say hes hiding until it arrived to not break her heart. Of course this is the last resort and I do not want to have to do that.

This picture is from this morning.
