National Fish Pharmaceuticals is the ONLY domestic source for pure Fenbendazole. 

USES:  Fenbendazole is used as a worming agent in tropical fish.  It is extremely effective in both fresh and salt water environments.  It has replaced Levamisole (Discomed) since the fish do not build a resistance to it.  Fenbendazole can be dosed either as a tank treatment or in the fish food itself.  It works so quickly that you will usually see worms protruding from infected fish within an hour!
