Dewormer & Beefheart Paste Food

by Luke Roebuck


BEEF HEART RECIPE With Fenbendazole
recipe is from James Alderson, DVM.


  • 1 1/2lbs of beefheart
  • 1tbsp. Spirulina powder
  • 1tbsp powdered krill or plankton
  • 2 cc of water soluble vitamins (baby vitamins will do)
  • 5.2grams of fendendazole paste (obtainable from me)
  • Carefully dissect the beefheart and remove all the sinew veins and fat from the red meat. Your guppies will choke on them if you leave them in. This should leave you with approximately 1 lb of de-veined, red meat. Cut the meat into small cubes and grind in a meat grinder or food processor to hamburger-like consistency. Do not use a blender to to this as the blender will fragment and destroy a lot of the muscle cell walls of the meat and catalyze the denaturing of the meat proteins in the cells. This will cloud and pollute the water when fed to your fish. When the meat has almost reached the desired consistency, add in the Fenbendazole, vitamins, Spirulina, and plankton/krill ingredients and continue grinding. If the mixture thickens too much to grind properly, add a small amt of water to the paste.

    When finished, put the mixture in to Ziploc sandwich bags and flatten with your hand on a smooth surface (table kitchen counter). Bleed out all the air in the bag and press to a thin (cheese slice thick) layer and seal the bags. Use a permanent marker to write the date and ingredients of the paste on each bag to identify and differentiate from the other paste foods in your freezer. You will also know how old the paste is in order to throw it out if you dont use it all after 6 months or so.

    Use the mixture while still frozen and break off pieces to give to your guppies. Feed mixture twice weekly for about a month or so, then once every few weeks as a preventative. This paste is generally effective against nematode infestation and can be used to treat Capillaria and Callamanus as well. It is well accepted and quite safe for the fish. Good Luck and May your fish remain healthy!
