Love The Fish
Brett....FWIW, and I am sure you are going to get TONS of advice here on the forum, but I have had tremendous results on two separate tanks using Aiptsia Eating File fish. they do work and you just have to be patient while they seek the Aiptsia over food. Some take to it quicker than others, but is DOES work from my personal experience. And FAR this expensive than your other options.
HTH and good luck............
Brett, I second this. It takes them a little time but one day you'll look and be surprised at how they all disappeared. I've never seen my file eat an aiptasia but they're all gone. My file will also nip the SPS a little but nothing too bad.
