How do I detach this rock anemone from the rock?

I don't want to to move this rock anemone to the 90 gal I am going to start soon but he is sharing the rock with my favorite coral, a big duncan.
How do I get it off the rock?

Try positioning a powerhead to blow directly at it.

like BTLD said, they get irritated and leave.
