Peppermint eats coral frags?

[Fishward]

Hey,
Came home with a Zoa frag this afternoon with a bonus Torch on it and left for a few hours for a beer and came home to a vacant frag! Torch nowhere to be found!.. would a peppermint eat a small torch coral?would a hermit crab? snail? who's my number one suspect?
want to string up one of them!... gah!
