Reef Pilot's Undersea Oasis

[Reef Pilot]

Thanks. That's a Pearlscale Butterfly. I have one in each of my tanks. Had them for almost 4 years now, and they keep my tanks clear of aiptasia. If you go back early in my journal, I describe my initial tank conditions and all the aiptasia I used to have. The Pearlscales totally decimated the aiptasia and have kept my tanks clear ever since. And contrary to popular opinion, they don't bother my corals (have all types incl softies, LPS and SPS). Plus they make nice peaceful tank mates and eat all kinds of foods.

Having said all that, you can't just buy them and plunk them into your display tank. They likely won't survive, and if they do, will probably go after your corals. But there is a way...
