Need quick ID on zoa worm

[Shnolby]

Found this on my zoa, doesn’t seem to be effecting it. The zoa still opens fully and acts normal. The fray is currently being dipped, but I have to manually remove the worm looking thing.

Possibly a Spirorbid, almost certainly a feather-duster of some kind.

I see no danger - others might.

if you are talking about the white swirly then it's just a Spirorbid Worm. Harmless filter feeder. The clear mass spreading on to the plug looks like a sponge.

Yeah I’m familiar with spirorbids, not worried about that. I was talking about the transparent mass, I’ve watched it grow over the past few days. I carefully brushed it off with a soft brush. It doesn’t move at all like a worm, so you might be onto something with the sponge guess. I did recently discover a bunch of pineapple sponges in the tank

that sponge isn't going to overtake your zoas Just don't give it to take AIR , because this will kill it, and isn't looking good after. If you get the same mass but black, then is better to take it off, because the black sponge is invasive.
