Zoa don’t have feeders. If those are part of the skirt that’s a first for me. Likely something living beneath the colony on your rocks. I have little tube snails (don’t remember what they’re called) that send out clear feeders from under my Zoa. (Not vermitids but another type). They don’t look to be bothering the Zoa in any case
