Voogle: First Aid For Fish Diseases Every fish has a natural immune system that protects him against pathogens that can cause disease. Such factors as transport, dirty water or a high level of pathogens in the water, place fish under tremendous stress. This uses a great deal of their energy and challenges their immune system. Particularly the mucous membranes, the gills and fins become extra sensitive to such diseases as (White) Spot, fungus and other types of infections. Voogle reinforces the health of fish and strengthens their immune system. The natural immune system is stimulated such that fish are able to resist disease better.  By administering Voogle weekly, fish are always protected in a natural way. This significantly decreases their susceptibility to a wide range of diseases.
