Guess the Hitchiker

Hey All,

Would anyone know what this could be? It's stuck on the live rock right on a valve, and it's black in color, a little fuzzy, and hasn't moved in a week or spreading.

Tanks a lot,
Jake

There are some zoa's there on the bottom left.
One above it, The blackish one, It looks like it has 2 heads kind of, Kinda looks like some sort of Acan. Does it have a mouth? Do tentacles come out of it?

No mouth or tenticles and I can't find a head. Its just like a glob of somewhat squishy black stuff
