Nick's Dragon

I just like this picture of Nick and his pet lizard, Dragon. He really like him. Dragon is getting a little skinny though and not eating. We took him to Petco and had him looked at. Hopefully he is okay. Let us know if anybody has any lizard expertise and can offer advise. We have had him for over a month, he he has shed once. He has both milworms and crickets in his tank and he doesn't seem to be be eating them. His teperature and humidity are both at the right levels. Hmmm? We're perplexed. But isn't it a cute picture though?! Dragon likes to climb on the little toy dinosaur Nick put in there.
