Why Switch to Homemade Fish Food?
Before we jump into the recipe, you might wonder why you should make fish food at home when it’s so easy to buy it off the shelf. Here are some key benefits:

Over time, making fish food can be more budget-friendly than constantly buying prepackaged options.
- Reduced Waste
Use leftovers or fresh produce from home, reducing food waste.
Now that we’ve covered the benefits, let’s move on to what you’ll need.
Essential Ingredients for Homemade Fish Food
The health of your fish depends on a good balance of proteins, fats, and carbohydrates, along with essential vitamins and minerals. Here are some common ingredients and their benefits:
Protein Sources
Fish thrive on protein-rich food, as it promotes growth and provides energy.
- Shrimp or Prawns (fresh/frozen): High in protein and palatable for most fish species.
- Fish Fillets: Lean, white fish like cod or tilapia can work well.
- Spirulina Powder: A plant-based protein source rich in essential nutrients.
Vegetable Options
Vegetables provide vitamins, antioxidants, and fiber—essential for digestion.
- Spinach or Kale: Packed with iron and calcium.
- Peas or Zucchini: Easy to digest and improve gut health.
- Carrots: Source of beta-carotene, which enhances coloration in fish.
Binders (Optional)
To hold the food together, use gel-based binders such as:
- Unflavored Gelatin: Keeps the mixture solid when submerged in water.
Supplements
For an added health boost, consider these extras:
- Fish Oil: Adds omega-3 fatty acids, enhancing immune function and coloration.
- Vitamin Supplements: Crushable multivitamins can be included in small quantities.
Mix and match these ingredients based on the dietary needs of your fish species, keeping their preferences and size in mind.
Step-by-Step Recipe for Homemade Fish Food
Ingredients:
You’ll need the following:
- 1 fillet of white fish (like tilapia or cod)
- ½ cup shrimp or prawn (fresh or frozen)
- ½ cup spinach (fresh or frozen)
- ½ cup peas or zucchini
- 1 small carrot
- 2 tablespoons spirulina powder
- 1 packet of unflavored gelatin
- 2 cups water (for boiling and blending)
Instructions:
- Prepare the Ingredients
- Thaw any frozen ingredients well in advance to ensure they can blend smoothly. This includes the white fish and shrimp if they were stored in your freezer. Let them sit at room temperature, or use a bowl of cool water to speed up the thawing process. Make sure they are completely thawed before moving on to the next step to avoid uneven textures.
- Boil the peas, zucchini, carrot, and spinach in a medium-sized pot of water until they are soft and tender enough to blend. This typically takes about 5-7 minutes, but you can test the vegetables by piercing them with a fork—they should be easy to mash.
- After boiling, carefully drain the vegetables and let them sit in a colander or on a tray to cool completely. Cooling is essential to avoid cooking the other ingredients during the blending process later. You can speed up cooling by spreading the vegetables out in a single layer or placing them in the fridge for a few minutes.
- Blend Everything Together
- Once the vegetables have cooled, place them in a blender or food processor along with the white fish, shrimp, and spirulina powder. To make blending easier, cut the fish and shrimp into smaller pieces before adding them to the blender. This ensures a smoother consistency and reduces strain on your blender.
- Blend the mixture on a medium to high setting until it forms a smooth, consistent paste. Check for any large chunks and continue blending until the mixture is completely uniform. The smoother the paste, the easier it will be for your fish to eat and digest.
- If the mixture is too thick or your blender struggles, add a small amount of water—one spoonful at a time—until you achieve the desired consistency. Be careful not to add too much water, as this can make the mixture too runny, which may affect the final texture.
- Prepare the Binders
- In a separate bowl, dissolve the unflavored gelatin in 1 cup of warm water. It’s important to follow the instructions on the gelatin packet for the best results, as different brands may have slightly different methods. Stir the water and gelatin thoroughly to ensure the powder is fully dissolved with no lumps or clumps.
- Allow the gelatin mixture to cool slightly before using it. You want it to remain warm enough to stay in liquid form but not so hot that it begins to cook the blended ingredients when combined. A slightly warm but comfortable-to-touch temperature is ideal.
- Combine and Mix Well
- Slowly pour the warm, dissolved gelatin mixture into the blender or food processor containing the vegetable and seafood paste. As you pour, stir or pulse the mixture to ensure the gelatin is evenly distributed throughout. This step is crucial, as the gelatin acts as a binder, helping the final product hold its shape when set.
- Keep mixing until the gelatin is fully incorporated and the entire mixture has a smooth, uniform texture. Take your time to ensure all ingredients are well combined—this will prevent any uneven consistency in the final food. Scrape down the sides of the blender or bowl as needed to make sure nothing is left unmixed.
- Shape and Set
- Pour the final mixture into a shallow dish, silicone mold, or ice cube tray, depending on the shape and size of food you want to create. Shallow dishes are great for making large sheets you can later cut into flakes, while silicone molds or ice cube trays are perfect for forming small, bite-sized portions.
- Use a spatula to spread the mixture evenly in the dish or mold for consistent setting. Make sure there are no air bubbles or uneven spots, as these can affect how the mixture sets.
- Place the dish or mold in the refrigerator and let it chill for 4-6 hours, or until the mixture is completely solid and firm to the touch. For best results, avoid disturbing the dish while it sets to ensure an even texture.
- Cut and Serve
- Once the mixture has fully set, gently remove it from the dish or mold. If you used a shallow dish, carefully run a knife or spatula along the edges to loosen the mixture before lifting it out. For silicone molds or ice cube trays, gently push the portions out from the bottom.
- Use a sharp knife to cut the solidified mixture into small cubes, flakes, or other shapes that suit the size and eating habits of your fish. Cut pieces small enough for your fish to easily nibble on without struggling.
- Serve the prepared food directly to your fish or store the portions in an airtight container. If you plan to store them long-term, place them in the freezer. When feeding frozen portions, thaw them slightly at room temperature or in cool water before serving to your fish. Always store unused portions in the refrigerator or freezer to maintain freshness and prevent spoilage.
Pro tip: Always clean your preparation tools thoroughly before and after making fish food to avoid cross-contamination.
Storing Your Homemade Fish Food
Proper storage is vital to maintain freshness and avoid spoiling. Here’s how to store your fish food correctly:
- Refrigerate: Keep a week’s worth of food in an airtight container in the fridge.
- Freeze for Longer Storage: Freeze the remaining cubes or flakes in a resealable freezer bag. Homemade fish food can last up to 3 months in the freezer.
- Portion Wisely: Only thaw small portions as needed to prevent waste. Never refreeze thawed food.
By storing it properly, you can ensure your fish always have nutritious, fresh meals available.
