Hmm the only thing I did was changed about 15% of the water. Next day i added salt, 2 table spoons for my 18 gallon tank. and now 3 days later my ghost fish looks tremendously better. Whatever it is, it's definitely helping the glass catfish
I've seen infections like this clear up themselves with good water conditions. On the other hand, some of the protozoal infections I suggested are susceptible to salt treatments.
