fish breathing fast

[corky66]

What are the causes of my fish breathing fast.
I have changed my water salt level good. Im getting ready to check p.h, nitrite , nitrate levels next. my polyps , zoos, leather and anenomes all seem to be doing fine, water temp is80-82 just checked and turned it down. gonna level it out at 78 soon as possible.
all help welcomed. What my first step.

How long have you had the fish? How did you acclimate it? You said you "changed your salt level". Did you do this gradually or a big change at once? Post your other water tests when you check them.
