So Does the battle with Aiptasia begin so soon?

[Kelesco]

Just started a salt tank and this is the 1st live rock I bought. I have looked a lot on the internet and I think it is Aiptasia, but because the stalk is down in a hole and I cant see it I just want to ask before I try to eliminate it. Thanks. http://www3.sympatico.ca/jhogue000/images/4.jpg

It's hard to say because the picture is a little blurry.
I would guess that it is Aiptasia and I would zap it with some Joe's Juice or your favourite Aiptasia killer.

Any rock you buy, any coral you buy, and any frag you trade is a chance to introduce Aiptasia.

I typically go with shoot first ask questions later when it comes to pest control.
