Looking for some help identifying the species

[MidlifeCrifish]

Just about finished with cycling my new nano tank, since I don't have fish yet Ive just been watching my live rock and I've been trying to identify this little clear donut shaped guy so I decided to sign up with this forum since its been my best source of knowledge so far!

Hi! Looking like possible big fat vermetid worm? Hard tube and a small net/web will come out of the tube when food hits the water. Need a clearer pic for 100% sure ID but this is my best guess. If confirmed, snip the tube off the rock as best you can and cover the area with super glue, they are invasive and not friendly

Hey footgal thank you that's crazy you could spot that out, from my initial angle it just looked like a clear donut but when I repositioned the live rock I could see that it's protruding through a hole in the rock
