Pile of worms (?) ID

[Glass Algae]

Hey so I’ve been noticing these guys all over my frag rack I thought it was poop at first but I started seeing more and more. Sometimes when my leathers are not expanded yet I’ll see a bunch of ‘‘em on the green hair algae that’s behind my leathers.
Sorry if this is a common ID just couldn’t find specific pictures to 100 percent it. I haven’t noticed anything destroyed. I did have one or two stables of zoas close and get covered with algae but I don’t think that’s related to the worms.

Time to clean the frag rack methinks! (sorry, no idea on the squigglies...)

I have used the turkey baster on it and they seem to just accumulate there. I see them in other places with darker backgrounds and they def move. Idk I’m at a loss
