That's a nice Lined Day Gecko you have there. Looks to be s WC adult. If you take a pic of his/her underside when its on the glass I will tell you it's sex. That cute little "puckering" of its lips is actually a mild case of "nose rub".

Also, is that stone the animal is sitting on Obsidian by any chance?

Thanks for sharing.
