I think i'm having an ick outbreak, 4 of my bettas show symptoms, two have white flakes instead of dots, and the other two have only a couple of dots. I'm not sure if it is ick or not, they are not acting sick. I use the same cups to do all of their water changes and just did a water change day yesterday. Should I treat all of my bettas with copper safe, even the ones that don't show any symptoms??
