Your inverts will adapt to the predators ,
they do in nature.
You will lose a couple not many but they will only come out at night while the triggers are sleeping.
Some will not harass them at all,
like stated above Sargassum's being one,Blue Jaws,Crosshatch's,most of the time Niger's and some Haw Black Triggers.
Triggers are awesome fish you will not be dissapointed on any of them you pick!!!
