Small tube worms on glass?

[krash7172]

I have a bunch of these in my frag tank. I have some aptasia and assumed they were baby nems so I got a file fish. It is eating the large ones but not these tiny guys. Then I realized they stayed small. I took a closer look with a lens (my eyes aren't great) and they appear to be a small tube worm. The largest one is less than 1/4" extended. Thought I would double check with the experts before scraping them off the glass.

They are just tiny featherdusters.

Tiny filter feeders, keep 'em, scrape 'em. Harmless

Thanks for verifying. Time to clean the tank now :)

Yeah I have some feather dusters similar to that kind, they grow on everything glass, rock, sand, shells...everything.
