What is this growing underneath my kenya tree?

[Skay]

I bought a kenya tree at a lfs about a month ago and today i’m looking at my tank and find this (see attached) growing under it. It looks like a clove coral but i have no idea how it got there. Did i just get a 2 for 1 deal? could someone help me ID this. First time using the site so i apologize if this is the wrong thread.
