I went to the pet store and noticed they had a panther chameleon and they said it was a Nosy Be but I noticed it didn't have any blue color. They said it is about a year old. Does anybody knows why he don't show any blue?
If it's the one on your hand in your avatar that is blue. That's a pretty typical shade of blue for them. But like cami said, they can range for more of a lighter green to blue.
He looks a little young too. He'll probably blue up some more. My last Nosy Be didn't get REALLY blue until he was 14-16 months old. He was pretty teal before then.
