Aiptasia or not?

This organism keeps growing and I keep finding more of them in my tank. I am fairly new and have had my tank for about 6 months now. They look pretty cool but im told they are dangerous. Let me know...

It looks to me like a Bartholomea annulata, often called a "Curlique Anemone". It is a member of the Aiptasia Family.

The 3rd and 2nd pics of the same one, just different angles. Do I take them out? I dont want them harming anything in my tank.

I agree they look like curly que anemone's. They are related, but they do not split and move around like pest aiptasias. They are occasionally sold in LFS even. I had one and my dad had one for quite a while and they never caused problems. The do grow long and tentacles though. Probably close to a foot.
