Are they hard or soft? If they're hard they are tube worms, harmless filter feeders, but multiply quickly.

They are hard but fragile I was hoping they were I got loads of spirabid worms but just wasn’t totally sure [emoji846] they crumble when pressed they started appearing about six months ago and now I’m over run with them [emoji106]
