Polyps in cave of rock work.

[thatone08]

Found these polyps(for lack of a better word) in a cave of of a rock I have zoas on. Not sure if they are actually some kind of polyp, or egg sacks of some kind, a type of pest anemone, or possibly just some crud built up under there. There’s about 4-5 of them.
