help with crab identification

i have two crabs that came in with my live rock that i can't find anywhere (identification.) both are small, only about a half an inch wide. one is just plain bright red and the other is white with brownish bands and his claws are dark brown. i saw the banded one picking at my live rock (he's wasn't really picking much off either) and the red one i've only seen a couple times, once just sitting on top of one of my snails. both are shaped kind of like a mythrax, not like a decorator or arrow crab, etc. small compact bodies.
does anyone have any idea what they could be?
