Hey was looking at one of my fish today in the 55 gallon tank. I just noticed that she has a white cloudy dot in the middle of her eye. I change out about 20 percent of water each week, and the water is in good standing. Is there something I can do for her? I really don't want to put meds in the tank if I don't have to, If there is a natural way of curing her, I would be more for it.
