Mine, that I own since now 2 years (and is now about 8 inches) , is with damsels, clownfish, Centropyge and Siganus is very kind. It doesn't touch to LPS nor to disk anemones. Not even to the small (1 cm) white starfish which are everywhere in the tank. The only live animal it did eat: snails, they may hide a few days but it always manage to got hem.

I have had several of this species of triggerfish and they have varied quite a bit individually in terms of how aggressive they were. One of them was so aggressive that I had to keep him/her in a tank alone because s/he attacked literally any other fish that was in the tank.
I had received the super-aggressive trigger from a friend who was fed up with him/her. I had another one of the same species who was very well-mannered and lived happily in a mixed tank with a tang, an angelfish, and a Sergeant Major damselfish--with absolutely no problems of aggression.
This species of trigger seems to be the least predictable (IMO) as far as how aggressive it might be in the tank.
