Big Surprise when you look closely

[Pan]

Wow, thought my damsel was eating my snails (i saw him poke him a couple times) but nope low and behold i notice one ugly brown crab in there today...seems like i will have to rip all the rock out to get him, as he looked (saw him briefly then he was gone) like a very nasty crab i saw on reef central. Anyone have any surefire crab catching methods? ( no sitting on toilet seat jokes please) or is ripping out the rock the only way?

edited (1/2 later) whoa he has a hord of bloody snails/shells i his little area damn...i gotta find him, move the rock around but i don't want to take it all out way tooooo much of it now, well maybe a can heat some old aquarium water up tomorrow and then put the rock without the corals on it in there...hmm..
