That is peat moss, it just has a little bit of wood chips in it. He also has plenty of glued together rocks for him so slide into since I know he is SOME kind of Flatrock, just not entirely sure which kind he is. I don't think he is a troglodytes.
But yea definitely plenty of rocks though, I just scooted him out from in between one of them so I could photograph him better.
I got him at a semi-local aquarium/pet store, they mostly specialize in fish and aquarium stuff but always have a pretty large selection of reptiles, insects, and arachnids. As far as arachnids go they always have the basics like Emperor Scorps and Rose hair tarantula, and then occasionally get some less common stuff, so I pay them visits every couple weeks to see if they have anything interesting and found this, it was labeled as a Flat Rock Scorpion, but didn't say exactly what it was, so I am asking you guys to identify it. Length-wise, he is slightly smaller than MOST Emperors, but not by much...I could take another photograph of him next to a quarter if you like.
Just confirmed through some research that this is indeed a Hadogenes paucidens, aka "Banded Flat Rock Scorpion".
flat rocks are interesting looking species and if you have a set up like mine where they have SO many places to hide it cool seeing them run away from your hand and slip into a very thin crack. But other than that VERY boring.
