Need help to ID what seems like a Hitchhiking coral?

Hello, i recently acquired a Kenya Tree coral on a small rock. It has this little friend next to it. Any idea what it is and what to do about it?

Thanks!

It looks like an aiptasia anemone to me. You'll want to kill it soon as they can be very invasive and hard to control if allowed to spread. AiptasiaX is a good solution in my opinion, but there are many other home remedies that work too.

Thanks! So i decided to remove that rock completely and tried fragging the Kenya tree by cutting a couple of branches and hoping they'll reattach.
Since i never had aiptasia in the tank I'm hoping it didn't create copies of itself on other rocks/sand in my tank!
