I've been using an old recipe which doesn't require cooking but recently came across this on http://www.rockymountaindiscus.com/Disc ... recipe.htm :
THE INGREDIENTS
3 pounds beef heart - cleaned & defatted & trimmed
2 pounds raw shrimp - peeled
1 pound white fish
1 pound liver (we use beef) - trimmed & rinsed well and soaked in very hot water 3 minutes
2 pounds frozen plankton - thawed, or 6 ounces freeze dried - well rinsed
2 boxes frozen spinach- steamed lightly
1 box peas- steamed lightly
Note: It is best to obtain organic beef products that are raised free of bovine growth hormone (BGH) and antibiotics.
Run all ingredients through a food processor. When everything is processed mix well in a large bowl.
Add the following: They may be obtained at your local health food store.
6 raw egg yolks , 1/3 cup kelp powder (a seaweed) , 1/4 cup brewers yeast , 1/2 cup wheat germ and 1 tablespoons spirulina powder.
One tablespoon vitamin c powder. Mix thoroughly.
THE BINDER: At the health food store get some agar powder. Not the stringy stuff, not the pellets. Get the powder. The eggs and shrimp in the discus food recipe also help bind the food. Stir in 30 grams of agar agar. Mix well. To activate the agar binding we will heat gently in the oven. Set the oven at 200 degrees Fahrenheit (warm setting). Line cookie sheets with wax paper. This makes it go much easier later on. Smooth the food onto the wax paper lined cookie sheets around 1/2 inch thick. You will use several pans. Place the sheet in the oven for 20 minutes. Next cool the pans. Place them in the freezer. When frozen remove and cut into blocks. Store the blocks in high quality freezer bags. We've come this far- so why skimp now? The blocks can be precut into cubes if desired. Four ounce or eight ounce portions can be made with dewormer or desired medication if needed.
Does anyone else cook their Discus tucker? Wouldn't cooking the tucker make it lose it's nutrient?
