The Ultimate Guide to DIY Beef Heart Fish Food: Tips and Recipes

Feeding homemade beef heart foods to your fish can be a rewarding experience for fishkeepers who want to take a more hands-on approach to their pets’ nutrition. Let’s delve into the pros and cons of this feeding method:

Pros of feeding homemade beef heart foods to your fish:

Nutrient-rich: Beef heart is an organ meat that is dense in proteins, essential amino acids, vitamins (such as B12, B6, and riboflavin), and minerals (such as iron, zinc, and selenium). This nutrient profile can support the overall health, growth, and development of your fish.

Palatability: Many fish species are naturally carnivorous or omnivorous and are drawn to the rich and meaty taste of beef heart. This makes it an excellent choice for enticing picky eaters or those transitioning from live foods to prepared diets.

Customization: Preparing homemade beef heart foods allows fishkeepers to have control over the ingredients used in the recipe. By incorporating additional nutritious components like spirulina, garlic, or vitamins, you can tailor the diet to meet the specific dietary needs of your fish, especially for species with unique nutritional requirements.

Cost-effective: In some situations, feeding homemade beef heart foods can be more economical than purchasing high-quality commercial fish foods, especially for fishkeepers with multiple tanks or a large population of fish. Buying beef heart in bulk and freezing it for later use can further reduce costs.

Cons of feeding homemade beef heart foods to your fish:

Nutritional balance: One of the challenges of preparing homemade fish food is ensuring a well-balanced diet. Fish require a diverse array of nutrients, and an imbalanced homemade diet may lead to deficiencies in essential vitamins or minerals. Inadequate nutrition can impact fish health, growth, and reproduction negatively.

Contamination risks: Handling raw beef heart poses contamination risks, as it may carry harmful bacteria, parasites, or pathogens that could be transmitted to your fish. Thoroughly cleaning and disinfecting equipment used for food preparation is essential to mitigate these risks.

Time-consuming: Preparing homemade fish food can be time-consuming, requiring research, sourcing fresh ingredients, proper preparation, and portioning. It might not be a viable option for fishkeepers with busy schedules or those seeking a convenient feeding solution.

Why feed beef heart to your fish?

Beef heart is a popular choice for fish food due to its high protein content and nutrient profile. Protein is essential for muscle development, tissue repair, and overall fish health. Additionally, certain fish species, like discus and angelfish, are known to thrive on a diet rich in animal proteins, making beef heart an ideal choice to support their growth and well-being.

What is beef heart fish food?

Beef heart fish food refers to a homemade diet prepared using fresh or frozen beef heart as the primary ingredient. To create this food, the beef heart is typically minced or blended into a paste and combined with other ingredients like vegetables, vitamins, and supplements to form a well-rounded and nutritious diet for your fish.

Is beef heart good for fish?

In moderation and when properly prepared, beef heart can be a beneficial addition to a fish’s diet. It offers a rich source of high-quality protein and essential nutrients that can enhance fish health, coloration, and reproductive behavior. However, as with any food, it should be used as part of a balanced and varied diet to ensure all nutritional needs are met.

Health benefits of feeding beef heart to your fish:

Feeding beef heart to your fish can have several health benefits

Growth and development: The high protein content in beef heart supports optimal growth and muscle development in fish, particularly in fast-growing species.

Color enhancement: Many fish species exhibit more vibrant colors when fed a diet rich in high-quality proteins like beef heart. This is particularly noticeable in species like discus and cichlids.

Reproductive behavior: Proper nutrition can stimulate spawning behavior in certain fish species, and the nutrient profile of beef heart may contribute to their reproductive success.

How do you feed beef heart to discus?

When feeding beef heart to discus fish, it’s essential to offer appropriately sized portions. You can cut or blend the beef heart into small, bite-sized pieces that are easy for the discus to consume. Some fishkeepers prefer to offer the beef heart either fresh or frozen after thawing, while others may prepare and freeze small individual portions for easy feeding.

Why feed homemade beef heart instead of commercial or store-bought food?

While homemade beef heart foods have their advantages, commercial or store-bought fish foods also offer valuable benefits:

Nutritional balance: Reputable commercial fish foods are formulated to provide a well-balanced diet, ensuring that your fish receive all the essential nutrients they need for optimal health and growth.

Convenience: Commercial fish foods come in various forms, such as pellets, flakes, and frozen foods, making them easy to store and dispense. They are a convenient option for fishkeepers with busy schedules or multiple tanks.

Quality control: Reputable commercial fish food manufacturers adhere to strict quality control measures, ensuring that the food is safe and free from contaminants, providing peace of mind to fishkeepers.

Dietary variety: By offering a mix of commercial fish foods along with occasional homemade beef heart treats or live/frozen foods, you can provide your fish with a diverse and nutritionally complete diet.

What other foods are good options for fish when not feeding beef heart?

When not feeding beef heart, there are several other excellent food options for your fish:

High-quality commercial fish pellets or flakes: These foods are specifically formulated to meet the nutritional needs of various fish species and are readily available at pet stores or online.

Frozen or live foods: Foods like brine shrimp, daphnia, and bloodworms are rich in proteins and can be used as occasional treats or supplemental feeding for carnivorous and omnivorous fish.


Fresh vegetables: Some herbivorous or omnivorous fish can benefit from occasional vegetable treats like blanched spinach, zucchini slices, or peas.

Tricks and tips

1. How to prepare and freeze for ease of feeding fish

There are two excellent methods for freezing your prepared fish food: using zip lock bags or silicon candy molds or ice cube trays.

Freezing your fish food in candy molds or ice cube containers is a straightforward process. Simply fill them with the prepared food, freeze, and you’re good to go. However, it’s a good idea to transfer the frozen food into zip lock bags to maintain freshness and prevent any unpleasant odors in your freezer.

Personally, I prefer the zip lock bag method due to its simplicity and cost-effectiveness. Place the food in a zip lock bag and spread it out until it’s about ¼ inch thick. This thin layer makes it easier to break off pieces for feeding. To make the process even more convenient, you can use a butter knife to create creases in the food, further facilitating portioning during feeding time.

2. You can add medication to this food.

3. Beef heart has very little fat (which is why it is used) so it doesn’t stick together well. Which is why most recipes have another form of protein such as shrimp or salmon. 

4. Since you don’t want the food to break apart and pollute your aquarium, the binder is crucial. Be sure to carefully follow the binder-making steps provided.

Bing Seto’s Beef heart Recipe

  • 2 pounds of beef heart
  • 1 pound of shrimp
  • 1/2 pound of “Ginger Spirulina Flakes”
  • 1/2 pound of “Ginger Color Flakes”

Chad Fontaine’s Beefheart Recipe

  • 1/2 Beef Heart (raw)
  • 12 Prawns (uncooked w/shells) (can be substituted for raw shrimp w/shells)
  • Spinach (approxamate liquified quantity as prawns)
  • Split Peas (simmered until tender, same quantity as spinach)
  • 4 tbsp. Oat Bran (cooked smooth)
  • 4 tbsp. Wheat Germ (raw)
  • 2 tbsp. Gelatin powder (I use 2 packets of “Knox unflavored gelatine”)

Instructions 

  • 1. Prepare the Beef Heart: Remove any fat, gristle, or sinew from the beef heart and chop it into 1″ square pieces. Freeze the pieces to make them easier to grind.
  • Blend the Beef Heart: Once frozen, place the beef heart chunks into a blender and grind them until the texture is fine but still chunky. Avoid over-blending to prevent liquefying.
  • 2. Prepare the Prawns/Shrimp: Blend raw prawns/shrimp, shells and all, in a blender. Add water if necessary to achieve a smooth paste. Strain the paste to remove any large particles, particularly pieces of shell.
  • 3. Prepare the Green Ingredients: If desired, cook split peas until tender and blend them. Thoroughly wash spinach and blend it, adding water if needed. Strain if necessary to remove chunks and strands.
  • 4. Prepare Oat Bran and Wheat Germ: Cook oat bran until smooth. In a large bowl, mix the oat bran, raw wheat germ, beef heart, and prawns/shrimp. Adjust the consistency by adding more wheat germ if needed.
  • 5. Cook the Mixture: Use a double boiler to heat the mixture until it becomes grainy and tends to separate slightly when stirred. Add gelatin to the hot mixture to help it coagulate.
  • 6. Cool and Freeze: Spread the mixture on a cookie sheet to cool. Once cooled, cut it into squares and place them in zip-loc bags. Store the bags in the freezer.
  • 7. Feeding: Take out a piece of the frozen mix for each feeding and return the rest to the freezer. You can shave slivers off the frozen portion directly into the tank, and the food will thaw quickly in the water.
  • 8. Medications and Vitamins: You can add medications and vitamins either directly to the mix before freezing or by soaking or painting them onto the bite-sized pieces before refreezing.
