At first the thought of making your own fish pellet food may sound strange, but it is a simple and easy process that has many benefits for both you and your fish. Making your own fish pellets food, while a messy endeavour, is a cheaper and sometime more healthy alternative to store-bought fish flakes, which often contain large portions of wheat flour filler. Customise your homemade fish food to the species of fish that you keep, which often increases the quality of their diet and assists in maintaining health.
Mix all of the fish diet ingredients in the food processor and blend into a fine paste. The ingredients of your fish pellet mixture should be tailored to the species of fish you keep. If your fish are primarily carnivorous, use meat ingredients such as fish, beef hearts, mosquito larvae and krill; if herbivorous, use leafy greens such as spinach and kale.
Add the mixture to a large pot, add water, and bring to a boil.
Stir in gelatin mix and then allow the liquid to cool to room temperature.
Fill ice cube trays with the fish food-gelatin mix and then place in a refrigerator for 24 hours to allow the gelatin to solidify.
Split cubes into appropriate feeding portions for your fish and then place the pellets in the freezer to store.
Thaw frozen pellets before feeding your fish.
You may have to experiment with the combination of ingredients to find the right mix for the fish in your aquarium.
