by Rahim Mohamed 06 Jun 2024

This modified beef heart recipe uses 100% fish protein, incorporating pink salmon, yellowfin tuna, and prawns. This mix provides a highly nutritious diet for your discus fish, promoting health and vibrant colors.


  • Pink Salmon: 4 lbs
  • Yellowfin Tuna: 2 lbs
  • Prawns: 2 lbs
  • Eggs: 2
  • Multivitamins: 5 tablets
  • Pro-More: 100g
  • Pro-Gro: 100g
  • Spirulina: 2 tablespoons
  • Gelatin: 2 packs


  1. Prepare the Ingredients:

    • Thaw the pink salmon, yellowfin tuna, and prawns if frozen.
    • Break the multivitamins into a powder form for easier mixing.
  2. Puree the Fish:

    • Using a blender, puree the pink salmon, yellowfin tuna, and prawns until you achieve a smooth consistency.
    • Optionally, you can also use a food processor for this step.
  3. Combine the Ingredients:

    • In a large mixing bowl, combine the pureed fish with the eggs, multivitamins, Pro-More, Pro-Gro, and spirulina.
    • Mix thoroughly using a potato masher or a sturdy spoon to ensure all ingredients are well incorporated.
  4. Prepare the Gelatin:

    • Follow the instructions on the gelatin packs to prepare it. Typically, this involves dissolving the gelatin in hot water.
    • Once the gelatin is prepared, mix it into the fish paste thoroughly.
  5. Spread and Freeze:

    • Spread the mixture evenly onto cookie sheets to create a flat, uniform layer.
    • Place the cookie sheets in the freezer and allow the mixture to freeze completely.
  6. Cut into Cubes:

    • Once the mixture is frozen, use a bit of hot water on the underside of the cookie sheets to release the frozen paste.
    • Cut the frozen paste into cubes of appropriate size for feeding your discus fish.
  7. Store:

    • Place the cubes into Ziplock bags for easy storage and convenience.
    • Keep the bags in the freezer to maintain freshness and prevent spoilage.

Feeding Instructions

  • Feed your discus fish a small number of cubes once or twice a day, depending on their size and number.
  • Monitor their intake to avoid overfeeding and ensure they consume the food within a few minutes to prevent water quality issues.

Nutritional Benefits

  • Pink Salmon and Yellowfin Tuna: Provide high-quality protein and essential fatty acids.
  • Prawns: Rich in protein and minerals like zinc and selenium.
  • Eggs: Supply additional protein and essential nutrients.
  • Multivitamins: Ensure your fish receive a balanced array of vitamins and minerals.
  • Pro-More and Pro-Gro: Boost growth and health with essential nutrients.
  • Spirulina: Enhances color and provides vitamins and antioxidants.
  • Gelatin: Binds the ingredients together and provides collagen for healthy skin and fins.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
