Fast pace Gill pumping

[Reefnoob84]

So all of my fish are breathing a little fast. I did the checklist all good. I have 9 total fish in my 75 reef with aquacev180, 55 gallon sump and almost 140lbs lr. No visible signs of infections. All of them eat like they haven't for days. No clue why but it's been like this for a week. There's plenty of surface movement on both sump and dt. I'm flowing about 700 gph through the sump and 2 1650 aqueon and 1 750 ph. (soon to be 2 mp40's )

These are in a 75? It's stress related.

They all get along great never any territory problems. No aggression ever except the clowns witch are juvenile too. None of the fish are bigger than 3 inches
