Looks like it. Aiptasia do not bunch up like that.

Thanks I always thought these were hydroids though? They are more of a brownish color. I have some of these as well but they clump up in a group. Stole this pic from the web

According to the site, they will slowly go away when they run out of food source....really?

Pretty much. They'll come and go in our systems.
