I have a 20 gallon tank with 2 Flame dwarf gouramis, 4 harlequin rasboras and 4 white clouds. Shortly after I got the white clouds they came down with ich. I think it was related to stress because their fins were being nipped by some guppies that have been moved to a different tank. I have been treating the ich with freshwater salt for nearly two weeks now (The instructions said two teaspoons for every gallon). The ich seems to have gone away for several days now, but there appeared to be one persistent spot on the "noses" of the white clouds. I just thought it was a persistent parasite, but recently the white spots have turned into "bubbles." Is this the ich on its last legs or something completely different? Is it even a problem? Any thoughts or ideas would be appreciated.
P.S. I will be lowering the salinity levels soon after I can figure out what's going on.
