Emerald Problem?

[Zoe]

Hi,

A few months ago I got an adult male ETB. His price was slightly lower than normal, so I was a little apprehensive, but I went to see the seller's place and it looked great. He explained that his prices were low because he sold, for the most part, to petstores, and that he bought in bulk. He told me that the ETB I wanted was from a breeder in South America, and that he was eating and healthy.
I brought him home and though he didn't eat and had a small mite problem, he was fine - active, healthy looking and alert.
A month or so later I moved, and took him with me. Up till now he hasn't eaten and though he could stand to gain a little weight, he is by no means terminally skinny, and seemed to be doing well.
However, he doesn't seem to be doing so good now. Normally when I clean his rubbermaid I do it as unobtrusively as possible, but today I thought it was time for a complete scrub down. I took him out and noticed he was very, very listless. He still responded to things like me taking him out, spraying him with water etc, and he is always on one of his branches, but he seemed a little out of it. He wasn't flipping his head around but it seemed to be lolling a little bit, and when he got a little irritated with my looking him over, his "attack" seemed a little pathetic (a few lounges towards me with his head, but no hissing or striking. he's never hissed at me before but i thought he seemed a little pitiful today). His mites seem to be gone but because of my reluctance to use anything too strong (and knowing how mites are), he may still have a few that I have yet to kill.

Any ideas or suggestions as to what may be going on? Could it be a lack of food? Like I said, he isn't really skinny, but should I start trying new methods to get him to eat (ie braining, live, really hot, scented etc etc)? Could this be a result of some internal parasite? I'd rather avoid having to see a vet because first of all, there are no herp vets in this province that I know of, and second, I don't want to move him back and forth any more than necessary.

Thanks,
Zoe
