Help with posible sick dragon

Im looking for some help with my dragon, about a month and a half ago we got him a bigger cage about 3Xtimes the size of the old one, and since than he has been eating less and has lost some weight, altho he still likes his worms. Both cages has never had lids so im worried maybe about heat loss, but the heat lamp is normally around 100 - 110. Im hoping for advice on what to do maybe with the cage or with my dragon.

I don't really know anything about their care at all. But one thing I would guess on is that he may be stressed out from now being in a much larger enclosure.

But like I said, I really have no idea. Hopefully someone with experience will be along soon.

One of my dragons did not eat many crickets when I got her, but liked worms. After settling in for a few weeks she started eating more crickets. I moved the enclosures to an area that had a few degrees lower ambient temp and was in a more trafficked area. She stopped eating crickets pretty much all together, but would still eat worms if I gave them to her. She lost some weight due to lack of appetite. I moved the cages back to the original room which is a bit warmer and more secluded, now a week later she is eating crickets again.

Ambient temps and security would definitely be the 2 things to look at I think.

Thank you, Im going to have to try and fool around with the temp's a bit more until his good with it again, and I wa thinking about putting something on the bak on his cage since we moved he's in a much larger living room, im hoping that will make him feel more safe as well:D

How old is he and do you have pics of the setup/dragon? Temps and cage setup can do a lot but age/size of the dragon is also a factor. I'm guessing he's not a hatchling since you moved him into a larger cage.
