What is this?

[rhorn67]

This tubular shaped object has been growing under a mushroom. Can someone help me identify what this is?

Thank you

You'll get those from time to time.... eventually they will be all over. I have them and they are harmless. I forget what they are, as I'm pretty sure those arn't feather dusters. @Lionfish Lair should be able to help out!

More than likely it's a Chaetopterid/Spionid worm. When you move stuff around, there can be lots of these hanging from the bottom of the tank. Harmless.
