My tip is to let it go (sadly). They really do poorly in captivity and will most likely die within a few weeks. I've seen some people on here have success keeping them in a deli cup for long periods of time (2 yrs max I think?), but in a bigger enclosure they will literally attempt to climb up the walls until they drop dead from exhaustion. I caught one, and just as online information said it would, I watched it restlessly run from end to end of its enclosure until one day it was dead. It occasionally hid under bark, terraformed and ate like crazy, but it seemed super miserable otherwise. I would have let it go, but I live 3 hours from where I collected it and couldn't get it back to its desert habitat. I caught scorpions in the same area who are doing great, so I just think camel spiders are best left where they are. Try finding that post where someone kept it in a deli cup, might give you some tips.
