Fritz ParaCleanse treats and controls of a wide variety of parasitic diseases, such as Velvet, Hexamita, gill & skin flukes, and fish lice. These diseases can often be present on new fish and may go unnoticed since they can be very small and may be hidden internally or under gill covers. Signs of infection, such as scratching, flicking, odd and frequent twitching, or heavy breathing should be investigated closely as treatment may be necessary.
