I have about a 20-inch green carpet anemone in my 75-gallon reef. No problems. I had to move it once from another tank that kept leaking and once you get him loose from what he is attached to whether it be the tank or a piece of rock (I'd just take the rock with him) I scooped mine up in an extra-large mixing bowl that way I didn't damage it and just acclimated in the mixing bowl. Then you can just drain the water from the mixing bowl and release it into the new tank. Look no hands, ha ha! I like the power head idea best because when they get mad, they WILL move. I made mine mad so that he would move and I could build a PVC fixture to hold my rocks so that he would not knock them over. My carpet likes to have his foot in the shade and then sprawl out everywhere else.
Not taking sides between you and the wife, but if it were me (which some would disagree), would leave the anemone where its at and try to find some clownfish that will mix with it. Also, when looking for clownfish, I have found that buying ones that are in an aneone when you buy them are more apt to take to the anmone in the tank. Another thing I found was that tank-bred clowns usually have no clue what an anemone is and therefore, dont normally take to them. Made that mistake!!!
Good Luck
