Is that the MONSTER one in the frag tank? I almost bought him, but they said he may eat fish. i have noticed some worms in my rock. If Lukes "pantyhose" trick doesn't work, I may try this guy. What do you guys think the chances of him catching a fish are? My blue tang likes to sleep in the rocks, thats the one I'm worried about getting eaten. This crab is the biggest arrow crab I have ever seen!!!
