what is this sprouting in my tank?

Anyone know what this is growing in my tank, it's starting to show up anywhere there isn't coral. It looks sort of like a xenia but much more pink but it's definitely growing like it.

Looks like anthelia or clove polyps to me

Is it laying down a mat or are they just individual polyps? If it's the latter maybe Sympodium?
