Some softie in my zoa

[billy816]

I was looking at what seemed to be a baby snail on the left side of my zoa and when I got to the right side I saw this. It looks almost like a feather duster but with a soft tube and more feathers. Any ideas?

The pic is kinda blurry, but to me it looks like a feather duster worm
