I can't just grab them w/ some gloves or tweezers & rip them out of the tank?
Sure you can. But you sure don't want too.
You will leave parts of the pedal disk that will grow into fully formed anemones for every microscopic piece left behind. For every one you rip out you will get 6 or 8 more.
Try a large eye dropper. Maybe one of those baby things you use to give babies medicine. I have one that looks like a king size eye dropper. You could put a lenth of small diameter tubing on the end. It should work fine. You just need to put a dollop of kalk
on the oral disk. When you mix calcium hydroxide (aka kalkwasser, aka pickling lime) and fresh water (doesn't need to be hot) it will make a milk colored solution. Use 1 or 2 tsp in an ounce or less of water. When you squirt this concentrate into saltwater it "gels" up and will stay where you put it, for the most part. High current will blow it around so be careful.
