I need help! My tank has ick. I can't catch my two tangs or my puffer fish to give them a freshwater dip it would stress them to death. I'm currently treating the tanks with kick ick but haven't seen many signs of it going away. Neither of them have stopped eating there all pigs in that department. It doesn't seem to be affecting them at all but it is clear that they have ick and its just those 3 fish out of a dozen I have.
