I got this live rock from my LFS today and it has a bunch of these things on it. What are they?

aiptasia, kill it by injecting Aiptasia-X or lemon juice in its mouth. They are a harmful pest.

This is a fowlr tank so I'm not concerned with any coral being killed. Could I just use peppermint shrimp to keep them at bay?

Peps can be hit or miss, ap-x or joes juice works every time. Aiptasia can take over a tank if your not careful.
