My newest tank inhabitant. Yeah, I know, he's got black pointy claws(well,okay, the pictures don't show those, but he does

) so he's probably a fish killer. But I don't plan on having fish in a 5 gallon tank, so that should be fine

I got him today for a dime(lol. high roller) after seeing him on some rocks and figuring someone would eventually kill him. He's kind of a sandy colour with the black stripe on his back, black claws, black eyes and black(or maybe just dark grey?) bands on his legs. He's also got hairy legs. He likes to act like an
emerald crab and sit around picking at the rocks eating what he can find off of them and hides behind them.
Any ideas?
