Thanks for the input. He gets approximately 10 hours of total light a day; 3-4 outside and the remainder under a UVB tube and a full spectrum basking bulb (which he doesn't use) I'm quite sure I bought him wild caught, despite the assurance that he was not. (It was at a herp show, and the vendor seemed a bit shady) In any case, he was eating a bit better prior to the all the hot weather. What I am going to do is move him inside so at least he'll get a more significant night-time temp drop, and the cool side of his enclosure will be cooler during the day.

Thanks again for your input!
