Be advised that those appear to be Anemonia majano - a major pest anemone that under the right conditions can take over an aquarium much like aiptasia.
There is an article by Randy Donowitz in Advanced Aquarist if you'd like further reading.

Can you send me the link? I just finsished searching for it with no luck. I'd be very interested to read it. These anemones don't get bulb tips like majanos. Dr. Ron identified them as Actninia bermudensis here:

He says they can be a prolific pest as well, but from my own experience and from most of the threads I've read about them after doing a search for tulip on several boards is that they simply don't reproduce as quickly as aptasia, or majanos. They certainly don't seem to have a sting that irritates any coral I've seen yet. I started with 5-6 over a year ago. I probably have 50-60 in several tanks now. Yes they're prolific, but hardly
anything to be worried about as far as I can see.
Here Dr. Ron basically describes the same thing. Started with one, had hundreds 6 years later when he broke down his tank. Everything I've read about majanos state they'd be much more prolific than this, and that their sting is much more of a problem for their aquarium-mates.

It is interesting that chronoligically he starts off saying that he believes they're benign, and ends with warning folks that they can become pests, but his description of his experience with them certainly doesn't seem to be a particularly negative.
