Aiptasia ID picture

[DrBig]

I am certain this is aiptasia, glass anemone. Just want to get confirmation/suggestions. It is on the outside of a large snail shell recently acquired from the LFS, with several small stocks of kenya tree coral attached to the inside of the shell.
The concern is on the left side of the picture. On the right side I believe this is some sort of feather duster.
Sorry for the bad focus. These things are very small. Both are less than 1/4" in size (bow front tank).
Thinking of just super gluing the thing in while it is small, rather than trying methods like injecting or natural predators. But is it aiptasia?

I think what you have is a hydroid polyp (tiny, translucent white). It could be some other polyps and is a bit too small to tell, but hydroid is my first impression. These come and go on their own. Sometimes you will see a population explosion of them.

It wouldn't hurt to nuke it with joe's juice or kalkwasser paste just in case
