So, here's some information I posted on another forum:
Alright, can I panic yet? I got my pacman frog three weeks ago and he wouldn't eat, so I did as someone suggested and started putting mealworms in a dish for him at night. Every morning a couple worms would be gone and a couple would still be in the dish, but today I lifted up the dish to clean it and there were worms underneath it. I now suspect that maybe the worms were crawling out instead of getting eaten. In addition, I dug up the frog (he is ALWAYS under his substrate, I never see him) and not only is he the same size as he was three weeks ago, but he looked skinnier and seemed lethargic. What do I do? I can't even get him to open his mouth to force feed him and he seems to be wasting away.
I looked up why he wasn't eating and it said they don't eat during estivation. Is this what's going on with him?
He hasn't eaten at all ever since I got him. He's about the size of a quarter, and I've had him for three weeks.
