Is this a feather duster?

[D-Dub]

Found this little purple feather duster looking thing hiding in my polyps colony. Is it a feather duster? I've had this polyps colony for 6 months and this is the first time I've seen it! If I walk close to the tank, it shoots back under the coral and hides.

Here's a photo - I'll try to post a video below:

Looks like the head from a vermetid snail. When it shoots back in, is there a tube/opening showing?
Please when you post a video, 3 seconds goes quick- at least 10 seconds will be helpful

Here's a longer video and shows it shooting back when I stand up. Second video is from a different angle.

It was hard to tell from the first picture. But, yes that is a feather duster. I love those things! For videos, you now have to put them on youtube and "insert link" them to get them to play. It is really easy to put them on youtube.

Awesome! Glad I finally figured out what that was!

Re: Youtube: Good to know! Way easier that way.
