Josh,
After studying my fish more last night and seeing him harass my snails, as well as how he curls his tail (almost 90 degrees) most of the time, I have to continue to think that he is a puffer.
He looks very different from the photo of your filefish, though the similarities are striking, there's still significant tail fin and other color pattern differences from my fish.
Can you post a picture of your fish from the front so we can see how thick or thin it is? (Like taking the picture of the front bumper of a car). I wonder if this is not a distinguishing factor between puffers and filefish.
My puffer is thick, thicker looking than most of a my other fish proportionately. He doesn't have a "thin" profile like the others.
How about your fish?
