No clue...

I bought a Blue Symposium Polyp and found this on the live rock the Polyps were on.

Any clue what it could be?

Aiptasia sp. remove them.

Don’t rip it off the rock though! This will release spores and make a bigger problem! Look into aptasia x. Should be able to find it at your LFS or amazon. You just inject them with that stuff and they die.
