Best thing to do place it in your tank and makes sure the foot attaches (make sure powerheads are covered so they don't become anemone salad) and then let them move to wherever they are going to be. They are going to find the place that suits their needs and as long as nothing changes they will stay there! As for handling them, I have Rose Bubble Tip Nem's, a Sebae Nem, and a Mini-Maxi Carpet Nem. They all stick to my hand, but I feel no sting when they touch me. Some people are different though and are more sensitive to the sting and I believe some Anemone's have a stronger "bite" to their sting than others (not exactly sure on that).
