Did it occur suddenly? Or was it after a water change? Cloudy eyes don't go away that quick. It takes a few (2-3) weeks to completely clear out. Try changing water more often, I did water change each other day, with small amounts (about 10%). If in a week it does not get better, you can add in Melafix.
With Melafix, always read the appropriate dosing. Be careful with the Melafix, as there is 2 types available, the "normal" one and the "pond" one. The pond one is much more concentrate, hence why you have to read the dosing on the bottle carefully.
Hope everything goes back to normal soon.
