Pilot fish in a reef tank

[Slicktop]

Other than the fact that they grow fast and eat like crazy, has anyone tried to keep a golden jack pilot fish in a reef tank. I purchased these yesterday and they are in QT. I want more fish waste to feed my corals (low nitrate) and thought these should work. Other than them outgrowing my tank and having to remove them due to getting too big, are there any other concerns? They are nice looking fish.
