I have read that you put the rock into a shallow container of freshwater
then progressively add HOT water to it until the shrimp comes out or dies.
I'm sure this will kill off a lot of the algae/bacteria in the live rock as
well though.

Easier said then done!! I tried that didn't work, tried fresh water
didn't
work, got mad started shaking the rock madley and guess what the mantis
shrimp came out and flew right by my face. Scared the living sh*t out of
me!!!
