Are you just wanting to move it in the tank, or would you like to move it out of the current tank? Even if you get the anemone to move, in a 10 gallon tank more than likely it will just move back to the current spot it is in. From the looks of it, the anemoe is right under the lights, almost as close as it can get - so my thoughts are even if you manage to move it to another spot it will just move right back to where it is because of the lighting/flow conditions in that spot.
