What is this

I got some thing in my tank that looks like a baby feather duster but I am worried it's not what do baby feather dusters look like ?
 
I forget exactly what they're called, but harmless.

Does it have a hard tube that it hides in if disturbed? It's either a young feather duster or it's a small species, most likely.
Pictures are helpful.
