Question maybe someone else has had an issue with perhaps. In one of my show tanks I have a S. fryeri that I have had for about a year and a half. He's full size 6" and he has always seemed to breath a bit harder/faster than any other fish, but lately I have noticed he seems to be breathing harder than normal even for him. There are 15 other fish in the tank and they are all fine and not breathing hard at all. Water prams are good 0amm 0Nitrite 20-30Nitrate Ph 7.2-7.3
He eats fine, is active, and color is great, but just seems to have a hard breathing problem. Anyone else ever had a fish that does this?
