Filefish eat mushrooms and palys?

[Reef Pilot]

Dogface puffer sounds interesting. I understand they eat a lot, period... And probably grow fast, too. This is for a 33g QT tank, and would never put one in my DT. And his time, and duty, would probably be fairly temporary, too. The reason I was hoping for a filefish is that they are in some demand as aiptasia eaters, and should be easy to pass off to someone else.
