Hi, in my 11 gallon tank i have 3 platies. The tank had ich about 3 weeks ago and i treated the tank and tested the water everyday after the infection and the results were good. However, I realized that one of the fishes has a large white spot over both of his eyes. Its not like normal ich that they have smaller spots all over their body, but just these 2 large spots on top of his eyes. What could it be? Could it be a scar from the past infection?
Also, all the fish look healthy and happy. Hes had the marks for the past 2 days and he seems fine but I'm scared the tank is still infected. I treated the tank for 11 days with the temperature at 30 celcius.
