Pest feather dusters?

[GeorgeC]

Hey guys my tank has been doing really well however all of sudden I have noticed A TON of these really small pests that looks like small feather dusters but I am not sure what they are, there are tons of them living among my zoos and on my euphyllia skeletons. They don't seem to be harming the corals in anyway but I kinda wanna get rid of them I guess for aesthetic reasons. Any advice would be greatly appreciated!

They won't hurt anything and most likely they won't survive very long.

Bump on this. I have these same worms and they crawl under zoa flesh and bother them. If anybody knows what dip is best to kill them on frags. Would love the .02, thanks all

Bump.

Been looking, this is still the closest thing to what I have in my tank. Very new tank, right about the month mark. Yes there is a Zao, this was a test on a theory as I come from planted tank background and is working wonderfully. My first tank too. But... I still can't tell or find out what these are. They are now obviously multiplying but don't seem to both the Zao too much.

They are feather dusters, harmless filter feeders. They are technically worms.

These might be hydroids.. there are numerous threads about them, but generally once you see a rock with them crawling over it - it's best to nuke the whole piece straight away,,

Hydroids - How do I eliminate- They have taken over my tank

So I have this stuff that has pretty much taken over my tank and I can't get rid of it. I'm looking for an ID and an eradication plan that is anything short of a total teardown.

Hydroids should not cause harm - but they can be invasive..

they are indeed feather dusters, they've never bothered anything for me, and this many growing is usually a sign of a healthy ecosystem.
