Can anyone identify this?

Hi,
Is anyone able to identify what there are?
First I thought this was coralline algea starting up as my tank is a little over a year old, but this looks different to that..

they’re popping up all over the place now

Hello I’m not 100% sure but they look like Spirorbid Worms to me they are filter feeders harmless too I believe…

Its a little blurry but I’m quite certain those are spirorbid worms (they are filter feeders). You should find them on your glass as well. They arent harmful just unsightly. I wouldnt worry too much if they are on the rockwork but if they are on the glass, a magnetic scrapper or algae scrapper will get rid of them easily. Based on my experience they disappear as your tank matures usually by a year.

Probably Spirorbid worms - harmless filter feeders.

Yeap, spirorbid words. They pop up quickly. And if you look real close, you’ll see its feeding tentacles. I wouldnt stress too much about them.
