I'd do another waterchange. With the fish and corals acting stressed, there's something in the water that's bothering them. A waterchange should help dilute whatever that is.
I'd look into getting your own ammonia and nitrate test kits at the least. They're pretty cheap and easy to use, also very important things to know when a tank is less than a year old. How are you measuring salinity?
+1^ double check salinity as well zoas r quite sensitive to salinity issues. Id also toss in a bag of carbon just to b safe.
....... I'm Matt n i have a reef obsession.
