I have a few questions about my new Veiled Chameleon. I have had him a week and he isn't looking so good. He is normally a pretty green color but right now he is pretty pale looking, almost transparent. The temps are where they should be and his humidity stays between 50%-80% (which I was told was ideal). He isn't lacking an appetite and he doesn't seem any less active (at least he hasn't up until I got home and he wasn't looking good). The only thing that is worrying me is that he violently shakes for a second or two. I only noticed it once and my boyfriend noticed him do it once the other day. I don't know if it is more frequent or not since we both work during the day and can't always monitor the behavior (though up until today he has seemed fine). Also, when we are a distance away (no reason for him to feel threatened), he flares up (his stomach looks swollen and his neck area is all proofed up) and he opens his mouth really really wide for a few seconds and somewhat shakes (but not violent like before) though it all happened within a few minutes. He kept doing this multiple times and it has me worried. Is this normal behavior or do you think something may be wrong and I should get him checked out? Please help!!
