Worm I.D.??

Is this gonna be a problem? There are some popping up in the tank but mostly in the sump... Thanks

Just another type of filter feeder. Don't have specifics but I know it's not harmful.

It really looks like one of the little feather dusters that abandoned its tube.

Yea they are strange, they are actually in a solid calcium like tube on the glass (white) and their bodies slide in and out (dark brown)

They will spread down there and become a colony in time.

Yep. I have hundreds. They are neat after a while.
