Is this Aiptasia?

Title says it all.... it grew from nothing in my tank, and honestly I've kind of liked it. I originally just thought it was a good hitch hiker, but now it's dawned on me that it may not be the case.

I have not seen any others growing in the tank, and it doesn't seem to be bothering anything else in the tank.

If it is, thoughts on plans? Let it roll or should I take care of it before it becomes an issue.

Yes it is and Yes you should do something about it.

I've found that concentrated lemon juice in a syringe squirted directly on aiptasia is an easy way to get rid of it if there are only a few in the tank. You don't use enough juice to affect anything else unless coral or something else is next to it. Carefully direct the syringe close to the middle. Don't touch it or it will close but get close enough to get the juice directly on the middle. It will then close, but if you're close enough, it can't close all the way. Squirt until it withdraws. It will then die. If you try to pull it out, a tiny piece left will cause it to spread.
