Powder Brown Tang Sick!!?

[Salmon King]

As I also have saved many fish for people.I have never lost a fish with a freshwater dip.I never said it/s a cure.If your fish has velvet you only have 1 day to start treatment.The dip gives your fish a chance to live.Like I said put your fish in a quratine tank and treat with copper.I have tried cleaner shrimp and cleaner wrasses with little succes.I/m not saying other methods don/t work.I just know my method is fairly easy to do.
