Heh the first couple look neat but then after they turn into hundreds and kill all your other stuff they're not so neat.
I've had success with Joes Juice, I just slowly squirt it nearby the aiptasia moving in closer as I squirt so that it actually "eats" the stuff. Other people have had success with a concentrated kalk solution.
One thing about "treating" these things, just do a couple at a time, especially in a smaller tank. The release of the joes or Kalk can overwhelm a smaller tank (IMO) so I would just do a couple every few days with maybe a water change in between.
Perhaps someone that has treated them in a smaller tank can chime in here with their experiences.
