I had a Hippo Tang that terrorized my tank for the longest time- leaving dead fish in its' path of destruction. I had to catch it and hand it over to JL Aquatics.
Normally the new fish will get picked on for a week or so and then everyone figures out their role in the tank hierarchy. If it continues on for a long period of time, it will inevitably result in murder. Having said that, I have two clowns that have been scrapping for a year or so now but even they know their side of the tank and try to stick to their turf. CLowns are tough though.
Maybe you should send your trigger to his cousin's place in the trigger "hood" where he can learn to be a man.
In all seriousness, I wouldn't worry about it...yet.
