Thank you so much for your quick reply @jajeanpierre . Come to think of it, he had a bit of stuck shed in that spot when I got him two days ago, and it's gone now. But I'll keep an eye on it.
Thanks
Good evening,
Found a tiny black spot on the side of my young Jackson. He's about 6-7in TL, to give perspective for how small the spot in the picture actually is. He started to go dark when I got my phone close (he's only been with me for two days), but when he's calm it really stands out...
