I noticed a couple of days ago my black ghost was developing little white spots on his skin so I took a pic and showed the dude at my fish store and he said it was ich so I bought thos medicine to remove it and when I got home from the store I noticed my tetras were covered with it so anyway its about 4 days later and all the fish that were infected are starting to clear up even the black ghost but now the black ghost is almost looking like his skin is milky especially around his cheeks (or what ever that area might be) is he ok should I take him to the store so they can look at him or what????? Someone once told me that because they dont have scales they will shed occasionally if so is this what hes doing because his skin was damaged from the ich???
