Works well for pop eye
My Blue Beta fish recently had a pop eye infection in 1 eye, she seemed like she would die anytime, very lethargic, enlarged gills, floating sideways on the surface of the tank and not eating anything. I searched about pop eye on the internet and found Melafix, ordered it and used it for a week. I put my Beta in a separate tank and dosed her for 1 week, everyday changing 70% water. After 1 week sbe still had her fins showing some fungus so I co tinued the dose for 3 days more. Now she is absolutely fine and swimming around the tank tormenting other little fishes like before.😂

I love this stuff! It healed my fish back to her happy normal self! She had severe fin rot and a clouded eye. You just have to pay attention the the dosing instructions and adjust dosing measurements accordingly, based on the size of your hospital tank. I will say (as I didn't know this initially) it is best to fast your fish during the treatment process. This information is not included in the directions - I had to research and figure this out on my own. This way the medication can do its job effectively. Depending on the severity of your fish's illness - more than one treatment may be required. With time, patience, research specific to your fish, etc you will get your fish back to a healthy state in no time.
