Need better pics of the back of his rear feet (heels) to help with sexing.
From looking at your pics, seems like you could use some foliage in the set up. A nice live plant (cham safe) will do wonders in there!
Thank you for your advice, but it's a day old picture, since then I bought him a ficus. I will post a better pic for sexing later.
Can you tell how old is he though?
