I HAVE TO REMOVE A CARPET ANEMONE FROM A HUGE 20LB ROCK....

HE IS A SADDLE ANEM THAT WAS BURIED IN THE SAND WHILE OCUPPYING THE WALL OF THE ROCK.
I HAVE PLACED HIM IN A QT TANK WITH NO LIGHT, HOPING HE WILL START WONDERING. HE IS ALSO TURNED UPWARDS WITH NO SAND IN THE TANK.
CURRENTLY IT HAS BEEN 8HRS HOURS SINCE I MOVED HIM AND HE HAS LOOSENED HIS GRIP A BIT BUT HASNT REALLY MOVED ANYWHERE.
ANYBODY HAVE ANY POINTERS? THANKS!
