Unhappy Buenos Aires Tetra - swollen gills

I noticed on Saturday that one of my Buenos Aires Tetras has swollen gills. I have a 40g tank with 6 BA Tetras and 4 Corys. The tetra is not acting sick, she is active with the other fish and seems to be interested in eating (I haven't actually seen her eat because the back of my tank is a little dark). She is not struggling to breathe and has no other signs of disease. No one else is showing any signs of disease either. I haven't done anything new to the tank. I've had all the fish for about 8 months and the tank itself is about 12 years old.

Anyway, I cleaned the tank on Sunday (this is my regular routine and I thought that the water quality might be the problem). Today, Tuesday, I checked and she still has swollen gills (the left side worse than the right). Other than that, everything else is the same. I ran water tests and ammonia = 0; nitrite = 0; ph = 7.6.

So, I'm trying to decide what to do. I've read that aquarium salt could help but is not good for the Corys. I'm afraid to medicate because I've never had good results in the past.

Your thoughts?
