Other than low oxygen, is there any other reason my Chag would start slowing swimming with the very top of her head out of the water, gulping air and blowing bubbles? She started this 2 days ago.

I checked the O2 & it is 8 with a water temp of 72°. Not bad.
Ph 8
Gh 80
Kh 100
Ammonia 0
NitrIte 0

None of the other fish are doing this. She is the biggest bodied fish in the pond but not the longest.

I hooked up the spray bar tonight so I can't see if that helped.

Any suggestions?
