Dwarf/Fuzzy lionfish compatibility

[Corry Robbins]

I've been thinking about a Fuzzy lionfish or other small breed for my new reef tank. I do plan on keeping snails, hermits, emerald crab, and cleaner shrimp. my question is this, will the lion fish eat anyof these or any other fish? how large do fish have to be not to get eaten?
I know this might be a case by case senerio so id like a general pole. anyone had luck keeping small lionfish with crustations. please list the breed of lionfish to breed of crustation/inverts/small fish.

thanks!
