Little black lines on my baby's underbelly?

[SJM]

Thor has those little black barks all over his tummy, I've seen them commonly called stress marks and I'm wondering what they mean? Should I be worried?
I just got him a few days ago, and it could be relocation stress, but they've been there since he's come home and haven't gone away for a second!

He has the right lighting, right temperature (with slight fluctuation), poops and urinates regularly, and is eating mostly gut-loaded and dusted live crickets, though he has available veggies at all times. (Carrots right now, but he's not very interested in things that don't move.)

Also, could I get suggestions on taming the little guy? He's kind of like :x :x whenever I come into his space, so I've avoided touching him as much as possible to let him settle in. (Sometimes I pet him as an attempt of getting him used to my touch, and he usually lets me. I also pick him up when I mist him and he doesn't flee but he seems eager to get away whenever I'm done.)

So, black marks?
Taming?

Also, could anyone help me use one of his pictures to make an avatar? <_< I don't know how to reduce KB to lower than 16.

EDIT: The blackness of his underbelly has gotten worse since I posted this. Now under his chin it more looks like white spots and the rest is black. His tummy is still the same, but I'm afraid it's going to follow suit.

the black squiggles on his tummy and maybe under his chin are stress marks
do you handle him a lot? or change around the things in his cage a lot? if so STOP lol...and i wouldnt suggest putting a cave in there till he is over 6 months...he may become very shy and never come out again just leave him be for a few days...only go into his cage to put food in there...id say for a week...if you dont notice any changes go to a vet but if you do see changes...its just the marks from stress.
i know ppl say to bathe them a few times a week and thats a very important thing...but try to go a week without doing anything besides the feeding...and if you can *always helped my little guys acclimate better* put a sock or a small cloth that smells like you *not perfume or anything* into the corner of his cage...it will let him associate your scent with safety and that will also help the transformation process if you have any other questions...feel free to ask
