I need help! I lost all my fish in my 20 planted tank to ich while on a trip and my tank watching friend did not notice it in time. I did a water change and still treated the water with Super Ich Cure as directed even though there were no fish in the tank just to be safe. After waiting two weeks I started to add fish again.
Well it is back again and I am treating my tank with super ich cure again! But on day four of the treatment there are still white bumps on a few of the fish. What should I do? Is there anything else it could be? Should I try something else? Mind you I do have a yoyo loach in my tank so I know that could make some treatments different. PLEASE HELP!!!!
