pogoda coral parasite?

[ManEatingGuppy]

a few hours after feeding my fish i found some little white things eating my cup coral leaving trails on the coral. its white and gushy, its very sticky, i cant even blow it off with a turkey baster, it doesnt seem to move. their not no the heads of the coral. i also found a couple on one of my porites. is this some sort of parasite or is it just shedding or pooping?

If it looks like snail poop, it could be a montipora eating nudi. That's what it sounds like from thr description.
