Club tipped anemones

[Passionfish]

Over the past few months I have noticed 2-3, now about 10 club-tipped anemones in my 250 gallon reef tank. Nothing new has been added for a long time so I do not know where they came from, but more importantly are they a problem, can they take over the tank? Any info appreciated, I have only been able to find pictures online.

I doubt they would come out. They are very small, about 1/2 to 3/4 inch in diameter, translucent except for pinkish stubs at end of tentacles. They are like little flat discs with tentacles coming straightish up. I went online and looked at anemones and they look like the picutres for clubbed tipped so that's what I think they are.

I found a snorkeling case for my canon powershot. It works really well for aquarium photos and has a macro mode. Just soak in fresh water and dry before opening.
