What Is this?

Does anyone what this thing is in between my zoas? And how do I remove it?
I’m also working on my little algae problem.

I have no idea what that is, but I just got rid of some worms from my zoas by doing a hydrogen peroxide dip. I used the instructions in this article. https://reefstable.com/blog/how-to-dip-coral The instructions for peroxide are down the page a ways.
