Are these just feather dusters?

I’ve got a ton of these on this rock and way more in my sump. I assume they’re just feather dusters of some sort and are ok to have?

Yup looks like feather duster to me. Perfectly fine to have, good actually. I use mine as an easy sign of my water conditions. If the water needs changed they tend to stay in their tubes more. Good fresh saltwater and they are stretching way out! I probably have a couple thousands in my tank

They take over like crazy!

Yup, small feather dusters. They stay on the smaller side and are pretty neat to look at. Never caused me any issues.

Nothing to worry about, you are fine :)

Thanks guys :) yeah they started kind of popping up everywhere. May banish them to the sump so they don’t take over
