It didn't look like aptasia to me.

I think these are hydroids. They can be worse than aiptasia and will kill other coral with their stings. Look up controlling hydroids.

Agreed...harmless lil guys

 

[keithhays]

Definitely not feather dusters, but there is one way to be; sure feather dusters don't sting, these will.

These are harmless feather duster. Don't worry about them. They live in a tupe. When they retracted, you will still see the tube.
