Please help identify this anemone

[ppp021]

Can some tell me what kind of creatures are and how to get rid of them.
The biggest is about 1/3 inch. I saw the first one three months ago and during the last ten days are about 12 in different rocks.

I'm not sure that is an anemone so need the experts help.
Thanks in advance.

Look like a palythoa...

The chance of them being a Zoanthid/Palythoa are slim, as those species of coral spread gradually across the surface of LR and not through the middle and outward in random spots.

What about Majano Anemones?

Yea they're definitely an anemone, I have them too, but I don't have an ID. You can try Aiptasia X or you can inject them with lemon juice. That should work pretty well.
