Last night I bought a zoa frag and when I got home I noticed there was a tiny crab with zoa's all over his shell. He is not a typical decorator crab, his boby shape is different. His shape is more like the evil hitcher crabs you see people trying to get ID'd. He just hangs out near the main colony, he doesnt move much during the day and he doesnt seem to be munching them(plus if he was eating them why would he put em on his back). So..anyone have something like this or know what he is? I'll post pics sometime soon. Thanks for any help
