To catch a crab...

[ScubaSteve]

The other day I noticed a few of my xenia heads had been removed. Just gone. I suspected that it was either a crab or a nudi having a snack. I was sitting here working and saw out of the corner of my eye, in a little cave under my rock, two black pointy claws and a sandy-brown crab (about 1/2" - 3/4" across). Xanthid crab! Yay!

I'm normally cool with crabs in my tank, provided they don't go around messing my stuff up. I have a feeling this guy isn't going to play my rules, however, and he needs the boot.

Does anyone have any ideas to catch this little bugger that doesn't require ripping apart my rock? I'm considering baiting it into a jar, but I am about 100% certain that my cleaner shrimp will destroy that trap something quick.

And is there someone out there who would be interested in a free crab? Probably not.
