Chris,
Heres what I would do....(please excuse me if some of the sentences aren't gramatically correct; listenin' to Green Day as I type!)
I would, as everyone else suggested, put the little bloke on a small plant, and bounce luke-warm water off the side of the shower onto the plant and him. However, I would also DEFINETLY bring him to a vet asap. Chances are he will perscribe baytril, or a similar drug. Not to say that he is positive what the problem is (vets often diagnose exotics with medications simply because they don't know what the problem is but doesn't want to look bad because they don't know what they are doing), but it is worth a shot. Chances are, it is a respatory disease. I am almost certain. If it isn't, it is a parasite, which is a little rarer in this case, considering your circumstances, but describe your cage setup to me better and I can help more; better yet, get a pic. Also, where are you located; I can help you find a good vet.
Not to be pessimistic, but when a cham is as small as yours, it is very difficult, near impossible to help him once he starts "heading downhill".
Try your best, use common sense, read alot of books, even if it doesn't pertain to the problem at hand, and ask us any questions you might have. If a book doesn't have a chapter on illnesses, read it anyway; it is knowledge which you will need sometime in the future; and even if you don't "knowledge is power". Keep trying, and you will succeed. It DRIVES ME MAD when people like "eye-eatchams4fun" try to "drive away" new commers. And, untop of it all, act like he is such a good cham keeper!!! Lmfao, he is a fool. DON"T LISTEN!!! Stay with it, even if this one dies, you will get a nack for it soon; trust me.
As Frank Lloyd Wright once said: "I know the price of success: dedication, hard work, and an unremitting devotion to the things you want to see happen"
....Too, too true....
