Can anyone identify these?

I have these little grey tubes that keep appearing on my rocks. I’ll swipe them off but they always come back. They don’t ever move, they just kind of appear. Any ideas on what they are// how to get rid of them?

It’s hard to tell under the blue lighting. Could you take pictures under white light (ex. with a flashlight)?

Could be vermetid snails, feather dusters, hard to tell under blue light

+1. Might also be fish poo or a combination of these.

Yeah sorry, they’re so strange. Asked my local reef store and they had 0 clue. Thanks for your reply!

What fish do you have? If you blow em off do they blow to dust or just stay solid?

Looks like poop, what snails are in there?

Wow. I have astrea snails and a couple others. Didn’t know they go to the same spot over and over again that’s kind of wild
