Pest? Red Anemone with white tips

[moksha]

Hi everyone, wanted to see if anyone could help me identify these.
I've got a FOWLR, and recently these aptasia-sized anemone-type creatures started springing up. they have a brown base, but then are bright red with white bubble-looking tips. I know they are not the classic aptasia, which are brown and ugly--these things are pretty nice looking. I don't mind having them, since I only have fish, but would like to know what they are.
Any help would be appreciated!!

Look up majano anemones. If that's what they are, these are also pest anemones and should be removed.

Thanks for the help Viper.
I did a search on this site and found pics of the majano anemones, but unfortunately mine look different.

I tried to take a pic with my cell phone camera, but obviously it left much to be desired so I didnt post it.
More info--I've had the tank established for several years now, a 75 gallon tank with only fish and about 80 pds of live rock. Haven't added a new piece of liverock in well over a year, so not sure how these creatures even appeared....The reason I think they are a pest is because of where I found them, mostly in the corners and in areas with low water movement.
They are pretty nice looking, a deep fire red body with the white bubbles as tips on each arm. The mouth entrance is white also. They are all fairly small, about the size of a quarter with the arms moving around. they dont seem to move or cause any problems.
I've tried to search all I could, but I just can't find any pics that look like these things.
Any other suggestions?
Thanks again!
