Feeding your fish high-quality, nutritious food is essential for their health, vibrant color, and longevity. Instead of relying solely on commercial flakes or pellets, why not try making your own fish food at home? This homemade fish food recipe is perfect for both tropical and freshwater fish, using natural ingredients that support optimal growth and energy.
In this guide, you’ll learn exactly how to make fish food from scratch—cheaply, easily, and with wholesome ingredients your fish will love.
Why Make Homemade Fish Food?
1. Better Nutrition for Your Fish
Homemade recipes let you control the quality of ingredients. You can pack in vitamins, proteins, and healthy fats for a more balanced diet.
2. No Harmful Additives
Many commercial fish foods contain preservatives or fillers. With DIY food, you skip all that and go fully natural and organic.

Step-by-Step Recipe: DIY Fish Food
Step 1: Prep the Ingredients
Chop all vegetables finely after boiling or blanching them. Do the same with protein sources. Use a food processor or blender for a smoother texture.
Step 2: Blend Everything Together
Combine veggies, proteins, and any optional boosters (like spirulina) into a thick paste. Add a bit of water if needed.
Step 3: Add the Gelatin
In a saucepan, dissolve 1 tablespoon of unflavored gelatin in 1/2 cup of warm water. Stir until it dissolves completely, then mix it with your paste.
Step 4: Set the Mixture
Pour the mixture into a flat tray or silicone mold and refrigerate for 3–4 hours, or until it solidifies.
Step 5: Cut and Store
Once set, cut the food into small cubes or thin strips. Store in the freezer in an airtight container for up to 3 weeks.
How to Feed Your Fish the Homemade Food
1. Small Portions Only
Fish have tiny stomachs. Feed them only as much as they can consume in 2–3 minutes.
2. Use Feeding Tweezers or Hands
Drop the food gently into the tank. If you have surface feeders like bettas, let it float; for bottom feeders, sink it.
3. Monitor Their Reaction
Observe how your fish respond. If they nibble eagerly, you’ve nailed it! If not, you might need to adjust the protein or veggie ratio.
Tips for Customizing the Recipe
1. For Herbivorous Fish
Increase the amount of leafy greens and skip meat-based proteins.
2. For Carnivorous Fish
Add more shrimp, fish fillet, or bloodworms for protein-rich meals.
3. For Fry (Baby Fish)
Blend everything ultra-fine and use more egg yolk and spirulina for growth.
4. Add Variety
Rotate this food with other options like brine shrimp or high-quality flakes to give your fish a balanced diet.
Storage and Shelf Life
1. Freeze for Freshness
Store in an airtight container or ziplock bag in the freezer. Take out only what you need for the week.
2. Label the Container
Write the date on your container to keep track of freshness.
3. Avoid Cross-Contamination
Use clean utensils when handling the food to keep it hygienic and long-lasting.
