I just noticed this thing growing on my live rock, it must of just started taking shape a few days ago unless I'm completely blind.
It's raised almost like a half-circle dome. Looks like it has a coral skeletal structure that runs outward from the center radius. It's pretty symmetrical for the most part. Has like a charcoal ashy color to it with white 'arm like' protrusions. Almost the shape of a spider. It looks like it has a small something in the center of it. Almost like a mouth that a mushroom has.
Any idea on what it is or could be?
3 pics below, the last one I outlined the skeletal structure with red lines...
