Beef heart mix for growing fish

The discus have been growing well, and I feel that it is time to move them onto a more fish-based diet, so I have come up with a variation on one of the earlier recipes, with this beef heart mix for growing fish. As before, this beef heart mix is aimed at young fish, I used decapsulated brine shrimp, Spirulina, fish and spinach.


  • Type: fish food
  • Preparation time: 20 minutes
  • Total time: 1 hour
  • Yield: 500g


  • 75 g spinach
  • 12 g decapsulated brine shrimp
  • 1 clove garlic
  • 125 g beef heart (fat, arteries, veins and lining removed)
  • 125 g fresh or frozen fish
  • 25 g Spirulina
  • gelatin (enough to make up 500 ml)
  • water


  1. Soak the spinach in boiling water until it becomes soft
  2. Rehydrate the decapsulated brine shrimp, 25 g of shrimp needed 30-40 ml of water for rehydration
  3. Cut up the beef heart, fish and spinach into small pieces
  4. Mince the garlic (I use a garlic press for this)
  5. Place spinach, brine shrimp, garlic, beef heart and Spirulina into a blender, mixing until it forms a smooth paste (some people prefer to use a mincer)
  6. Make up the gelatin with 100 ml of water and add into the blender
  7. Mix the gelatin into the paste
  8. Place mixture into containers to chill before freezing (I use 9-10 10×15 cm grip-lock bags, placing approximately two large tablespoons into each bag)
