Yea I've done this trick with much saltier water to get a
mantis shrimp out of a piece of live rock. That mantis
shot out like a rocket :-)

The only think I didn't like about their rock was - it had some Mantis
Shrimps and some hairy crabs hitching a ride, and those suckers were
hard to catch.

The Foster & Smith web site had some advice about this. They said to
dump your rock into a bucket of salt water with an SG of 1.035 to 1.040
for one minute. They claim that all of the worms, shrimp, and crabs will
bail out of the rock. You can then move the rock to your tank or curing
bin and pick through the bucket to see if there's anything in there you
want to keep.

I've not tried this, but I intend to when my next order arrives.
