eSHa 2000 treats over 18 symptoms and desease organisms. For example, primary and secondary fungal infections (white or slightly off white film or fluffy growths on the mouth, fins or body of your fish), bacterial skin infections and skin/gill parasites, protozoan parasites (discoloured skin patches, cloudy fins, rubbing against plant, décor and gravel), ulcers and wounds, Dropsy, Shimmying disease and fin rot. An added advantage is its ability to assist wound healing and to protect the skin layer.
