Can a clownfish kill an anemone? My female ocellaris clownfish is pretty large, and likes to bite my fingers when I stick them in the tank. Lately she has taken to nipping at the mouth, and base of my Bubble Tip Anemone. It still take food, is attached, and inflates. I think it is healthy it's just more retracted than usual, and closes up when the clowfish bites it.
