Sometimes mine acts funny right after a substrate change and cage cleaning, even though I only use vinegar and rinse it out until I can't smell it anymore. I think they realize that something has changed about their cage, and it sometimes freaks them out.

If he continues acting funny and refusing food, you may want to move him just to check and make sure something else isn't wrong.
