I'm still figuring out how to use this forum and have just realized that you answered after my writing! You have been very helpful in all of your information.
It seems to me that I may have been overreacting and that Jeremy is doing fine for the most part (:

It is looking like he may just be constipated and I'm sure that would affect his eating. I decided on putting him in a 10 gallon tank for feeding, with moist paper towels and crickets only. I also took out the moss as I didn't know how could wind up swallowing it. I know he had crickets roaming his tank at the pet store so I think that I should keep it that way, rather than using a bowl or tongs since that's not what he is used to. After all, he is around a year old and has experienced quite a few changes!

How can I tell if he is active at night? The only evidence I know of is his water bowl having dirt in it. I have not seen him burrow since I last posted that he did, and he seems happier overall since his warm bath last night.

I'm glad to hear that his color changing is normal also, since his warm bath last night he has been climbing on his plants and has been a brighter green. I was going to do a honey bath tonight but I believe I'm going to have to wait until tomorrow. No feces in his tank that I saw, and I removed all of the crickets from his last feeding as well.
