Treating Eye Cloud

When it comes to "eye cloud" or "cloudy eye" it is said to happen due to a shift in low pH; dietary deficiency (lacking in Vitamin A); bacterial/fungal infection; or the presence of ammonia. Personally, I feel this is more related to a possible bacterial/fungal infection. What I found to work well as a quick remedy is API MelaFix which is used to treat bacterial infections. MelaFix contains tea tree oil which is often used as an antifungal and it also helps to repair damaged fins, ulcers, and open wounds.

Eye Cloud

Eye Cloud looks similar to fogged up water goggles, as it's just a smokey looking film over the fishes eye/s (in the image here you can see my fish Boba with some minor eye cloud appearing). It may be very likely that a fish that gets eye cloud continues to have some reoccurrences of this happening again in the future. Some other remedies I have come across online but not yet tried myself are Tetracycline Hydrochloride; Nitrofurazone; Sodium Sulfathiazole; Sodium Sulfamethazine; Sodium Sulfacetamide; Victoria Green; and Acriflavine. Nitrofurazone is the only medication I'm familiar with using when it comes to goldfish so, I would probably start with that if you're not having luck using MelaFix to clear up the eye cloud as this should clear up in a week.
