LionFish says......
Triggers feed manly on Crustacions(sp?) in the wild and they carry that trait over into aquariums. They are basically going to eat any invert you have with them. There are some people who get lucky but 99% of the time the invert gets eaten. So, avoid inverts with aggressive fish especially triggers, puffers, and lions. They will devour any inverts. And besides the trigger has extra strong teeth to break shells so it was a goner from the beginning.
