It shouldn't really touch any of your corals, but will eat any mobile inverts that you have such as crabs, shrimp etc....
I think the most it would do to any corals is to chew on them in an attempt to file it's beak down.
I've had one in my freshwater tank for a couple years now and it shreds apart any snails/shrimp I put in there for him.
You will want to acclimate him very slowly in a QT by raising the salinity over several days to a week.
They are known to get an aggressive streak to them, but I think it is more towards their own species. Mine has never gone anywhere near any of my fish and is actually quite shy.
