Iridescent feather duster ID

[tektite]

I was examining a coral I bought the other day, and saw this cool little hitchhiker. It looks like a feather duster, though I did see it has two thicker white tentacles as well (you can see one poking partway up in the right pic). The unique thing is its 'feathers' are clear and iridescent Very hard to photograph without a macro lens but you get the idea:

Any exact ID's out there? Google doesn't return much on this, lol.

I can't tell, is it a complete circle or a half circle?

Complete circle.

A guy on my local forum ID'd it as Flabelligeridae

Flabelligeridae

I just posted a thread of my own before I found this one. I too have (what I believe to be) the same species. I took a few pics. I would love to know more about them. they are just soooooo cool!

Bristle cage worms are quite fascinating I sold the coral mine lived in, I was sad to see it go...
