So I have had these fish for over a year, put them in the new 75g, did fine for a week, put a clown pleco in their (awesome little guy) bought the algae eater food that is like a cookie type with the algae in the center, now I'm assuming from the pieces that go un eaten, seems fungus is in the tank, treated it with ICK medicine, I know I'll do a water change soon about 25%, anything else I should know in order to keep away the ICK?
