Everything was fine a day ago, but I did chemiclean and I think that has caused them to start fin rot.
Ammonia: 0
Nitrite: 0
Nitrate: <5ppm
I added the correct amount of chemiclean it said too, waited 48 hours, then did 40 percent water change. Air stone was on the entire process. After the water change yesterday evening I took it out but noticed their fins didn't look healthy. These pictures were from this morning. As I went to post this one of them was swimming at the top and breathing quickly, so I'm assuming I still need the air stone. I put it back on now. I am confused however because I have two other fish that are perfectly fine.
Is there anything that I should be doing or that I am missing? There has been no changes to the way I maintain this tank for months, and the fish haven't had problems before.
