I was out of town for a few days and came home to 3 dead fish in my tank. Its a temporary home for my fish while I Am getting a new bigger tank. I have a 155 gallon tank with a small motoro in there with a red severum and some other small fish. I came home and 3 small fish were dead and the severum has ick spots real bad. I do weekly water changes of 30% minimum and the water parameters when I checked it last night were all good. Does anyone have any suggestions as to what I can use to fix my issue?
