2 weeks ago when I added my Haddoni I was worried about my fish. It put down it's foot slowly expand and was beautiful. No problem first week. I decided to feed it one day when I fed fish. My Koran angel grabbed piece of shrimp out of my nem and took a nickel size chunk of anemone with it. Nem has not opened fully since then, kind of cupped like a tulip, color good.....hoping my Koran didn't like taste. I was planning on adding two more...little bummed out.
