Coral Identification - Mushroom or Anemone or ???

[Marineman]

I have this mushroom/anemone looking coral, cannot find a picture in the website. It grew out from the LR which I have for about 2 years, noticed this creature more than 6 months back and growing bigger, anyone can tell me what it is?

Another picture of another one, there are 2 in my tank.

I believe its whats called a sand anemone. I think i've read up on it b4.

But then again i might be wrong.

Thanks guys, I did some checking after what you all have said. I think it is in this family of actinodendronidae, quite undesirable anemone.

Thanks again.
