Little thing growing on my rocks?

[gsw0716]

Super tiny so I don't know how i spotted it, but i noticed two little things growing on my live rock. Any identification would be helpful, thanks. I do have some pulsing xenia isolated on a rock in the tank, don't know if any made it on a different rock. Thank you.

Looks like a clove to me, hard to tell.

Thank you. I do have a clove frag as well, are they known to travel to other rocks? The frag is on the next rock over.
