My jardini has some white film on its upper mouth and its skin on the gills are also flaking off. I think it is bashing its head against the filter. Could this be some sort of fungus infection? I'm going to raise my water temp. to 86 degrees and add salt. Tank is 225 gallon. 0 ammonia, 0 nitrite, 5-10 nitrate, and pH around 7.4. Anyone else have any advise or past similar experiences?
