White worms on zoanthid. Filter feeders possibly? Please help.

Hey I am trying to figure out what exactly these are. They covered the base of this zoa (my personal favorite of the tank) after a cyano outbreak. After multiple months of work and a uv sterilizer that is under control but this seems to be left behind. Could this just be like a ditritus worm or pineapple sponge that are suffocating the zoas? Any help or ideas would be great. I have removed some of the quality heads to another tank but these are in a display on a large rock with would be tricky to remove. Thank you in advance. Hoping for not the worst case as i got other zoas in the tank.

I'm not sure I see what you're talking about. If it's the sand tubes, those are spionid worms and are easily brushed off (but aren't a problem if they stay).
If that's not what you're asking about, please indicate on the photos...

Thank you. That was what I was talking about. Just wanted some reassurance to what I was thinking
