I've had my WTF Dubstep for several months now. Recently I noticed he seems to be turning from a greenish color to a brown. I checked his belly, and there's no redness or irritation there or his legs. He's also eating and pooping normally. No odd behavior; still active, and not soaking more than normal.
I did add a new piece of decor to his cage a week or so ago; a large red/brown fake tree. With my pac, colors dulling out can be in response to being on a darker substrate, so I was wondering if that could be the cause?
Mainly I just wanted to see if the color change by itself was anything to worry about, and what typically causes it?
