Can't really tell but it might be aiptasia or majano
 
Can't see the picture very well (The site has issues with resizing the pictures and reducing the quality), but it kinda looks like a hydroid.
 
It does appear to be either a hydroid or aiptasia from the images I saw online. How can I tell the difference and if I need to rid them, how can I? I dipped this piece in Coral rx for a solid 10 minutes prior to placing in the tank.
 
Do they look like this:

Do they glow under blue lights?

It could be feather dusters. Hydroids look similar to feather dusters, but my hydroids would glow under blue/uv lights. Both can have a tube base.

Aiptasia has larger tentacles, where hydroids have hair like protrusions. No tube structure at the base either.

Doesn't really look like the hydroids, seems to have a tube structure at the base, but wider then a feather duster.
