[Reef Pilot]

A few years ago, I inherited a tank that had hundreds (maybe thousands) of aiptasia. They were everywhere, even the back glass was totally covered. Got a Copperband, but he didn't touch them. Too many to try any type of injection method.

Then I got a couple Pearlscale Butterflys and they went after the aiptasia like crazy. Even my Copperband then started to join in. It took several months, but they got rid of all the aiptasia (that I could see), except for the ones in the overflow and in the sump (which are still there). The advantage of the Pearlscales is that they leave my corals alone (didn't at first). I have all kinds of softies, LPS and SPS and no problem.

Unfortunately, I have now seen a few aiptasia reappear (I now have 2 tanks, so one Pearlscale in each), and the Pearlscales seem to have got lazy and won't go after them anymore, as when I first got them. However, there aren't a lot of aiptasia (maybe 4 or 5 that I can see), so maybe they are still keeping them under control. I suspect the Pearlscales may have got used to being fed, and their tastes have changed.

I also got some Peppermint Shrimps, but they don't see to be doing anything either. I tried Aiptasia X on a few that I could see and get at. They disappeared for a few days, but then reappeared, in the same spot. So that doesn't seem to work.

If I don't get anymore Aiptasia, I'll be happy, as I can live with just seeing a few in my tank. My overflows and sumps still have then, though, and have not cleaned them out of there yet.
