i have a couple of zoanthid and paly colony's that have a few aptasia anemone growing in them. my question would be is there any method of safely removing the aptasia with out killing the colony or polyps that are near. in one colony what ever i use will probably come in contact with the polyp near the aptasia. i can remove said colony's , can i use a scalpel or sharp knife outside the aquarium? any help appreciated
