Looks good

. Well planted.
It's hard to see, but I would remove all moss. If accidentally ingested, he'll end up in trouble.
Mist good (75-80%).
You can do a nice refreshing Pedialyte soak to give him some electrolytes while waiting for him to eat.
Take 1 part clear, non-flavored Pedialyte to 10 parts distilled or dechlorinated water. Pour some into his water bowl before he wakes. He can soak in it for about 15-20 minutes. Then rinse out his bowl and add fresh dechlorinated water. It's not as good as eating, but it will give him some vital electrolytes

. You can do this a few times a week, every couple of days for a week. It isn't something you can do too much of, but it can help. It's a bit like getting an IV bag of nutrients. Hopefully he'll start eating soon

.
I agree on getting a fecal test done if he does poop. Dr. Frye' office does them for around $20 or so. You just get a clean fecal sample in a new baggie. It's best to wear gloves so you don't contaminate the specimen. Send it to their office with a check, the name of the frog species, and the test you want done (frog fecal test for ova/parasites).
