Spirorbid worm. Harmless filter feeder. They're ugly if visible imo but they're easily scraped off.

I agree looks like a spirorbid worm. Newish tank? I asked the same question when my tank was first started. It's a good sign that your tank is growing.

Yes newish tank, been seeing more things popping up.

That's a dorvilleidae worm. Good CUC
