Black trigger, coral safe?

[Cosmojo]

I've got a nice big reef tank I'm looking to put a black trigger into (Hawaiian or Indian doesn't matter). I don't have an invertebrates in it, just lots of coral. I know they can go after mollusks, clams, ect but I'm concerned about my corals. Has anyone kept them in coral tank?

As far as I know, no one has ever complained about them picking on corals, just the size they get (can be over a foot).
