My betta's eye cloud doesn't seem to have cleared up in the week. I've done a full treatment round of "Fungus Cure" by API which cures things like eye cloud & secondary bacterial illnesses. I've also enhanced it by adding about 5 tsp. of aquarium salt daily (diluted solution)..and in the week I've been treating, it went down a little, but his left eye still looks swollen and like it has a little cloud left on it (its just not clear.)
