I have 3 anemones in my 65 gallon tank. My oldest is a white carpet anemone, about six inches when stretching out, then my purple condi, and then my green bubble tip. Anyways about a month ago, i noticed one tentacle getting bigger than the others. it has blown up to about 6 or 7 times the normal tentacle size and has another tip sticking out of the side. does anybody know what it might be doing?
