I have a pair of mocha clowns, a pink skunk clown and a potters angel, I have had all three for about 3 years and they are healthy eating fish. Occasionally I see one or two white spot on the potters at times so I know there ich in the display. I am getting ready to do a tank swap so I thought it would be a great time to do a fallow period and treat the fish while I fallow the new display, plus this will give the new display time to recover should anything go wrong with the swap. 76 days should be enough to fix all the issues. Now onto my question. Since my fish are all healthy, should I just simply treat them for ich during this period? I don't want to put them through any treatment that isn't necessary.
