How large is it, and is it full grown (how old is it)?
If it's full grown and around 3 inches, it's possible it's a female (or sub-dominate male) Demasoni. Females and sub-dominate male Demasoni are much lighter (not as vivid blue) as the dominate male. It's coloration is the same as the smaller Demasoni I used to have. But mine and all the pictures I've seen have the darker bars running all the way down the body. So don't take my word for it that it's a Demasoni.
edit: looking at more pics online, I doubt it is a Demasoni. But it's coloration is the same as my smaller one (the one I used to have).
