While shop-bought foods have plenty of nutrients and have been made to provide your fish with a good diet, they can be expensive and contain lots of chemicals and artificial ingredients.
Making your own fish food is a great way to give your fish a healthy diet and tailor the food to the exact dietary requirements of your fish.
Homemade fish food is cost-effective and perhaps a lot easier to make than you’re expecting.
The beauty of making your own fish food is that you can source all the products as sustainably as possible to ensure you are feeding your fish the best quality food.

Where to Start
Now, all fish eat differently so it is difficult to provide you with an exact science for your fish food. All of the following recipes can be adapted to suit your fish.
We advise that you check out the ingredients list on your current fish food. You can then use that as a model when creating your own fish food.
Pick out the top three or four ingredients to begin with. They will most likely be fish ingredients such as Shrimp, Cod, and Salmon.
Remember you don’t have to stick to just one type of fish food, fish enjoy variety and are used to having a variety of foods in their natural habitats.
Why not make a few of these recipes and try them out? It’s likely your fish won’t like some of them, some fish can be quite picky eaters, but that’s fine. You can just try adding more or less of certain ingredients to find the sweet spot.
What Equipment Do I Need To Make Fish Food?
To make the following recipes, you’ll need:

Which Food is Right for Your Fish?
Not all fish food is suitable for all breeds of fish. Some fish are carnivores, some are herbivores and some are omnivorous. This is not a lifestyle choice; this is specific to their species.
It’s important to understand which type of eater your fish is and consider the diet for your fish before you make fish food. Let’s take a quick look at each category.
Herbivores: Fish that only eat plants, are essential in maintaining a healthy ecosystem. Great at eating all the algae in your tank. Most Plecos are herbivores.
Omnivores: Fish that eat both plants and meat. The vast majority of fish are omnivores. Rainbow Sharks are omnivores.
Carnivores: Fish that only eat meat and other fish. An example is the Discus.
Leafy greens are great for fish, they are full of minerals and vitamins and they are great mimics of natural plants that would be found in their habitats. Spinach, Kale, Seaweed, and Lettuce are some of the options available.
You can also get some great live water plants such as Cabomba, Egeria, and Limnophilla. All of which are commonly available in pet shops.
Fruit and Vegetables are also rich in nutrients.
You can feed your fish an assortment of them including apples, pears, broccoli, and peas. Some fruit and veg can be fed raw, but usually, you should steam or blanch them before putting them in your tank.
Fish also love garlic!
Garlic has plenty of anti-bacterial properties to keep your fish healthy. It can also increase your fish’s appetite. If it’s being used for this reason you should crush the garlic and just rub the juice/oil onto the food. Alternatively, you can mince it and add it to any homemade recipes.
A lot of fish species love eating fish. The most popular types of fish food include trout, salmon, tuna, and cod.
Earthworms are also a great addition to any homemade fish food recipe. They are packed full of nutrients and are very cheap.
You can also add other aquatic animals to your fish food, including brine shrimp, squid, mussels, and larvae.
You can get live, fresh, and frozen fish food. If you feed your fish live food, only allow them 5 minutes to eat it and then clear the rest out to prevent rotting.
A little bit of fat is ok for your fish, if your fish is a carnivore he can eat up to 6% concentration of fat, but don’t over-feed them with high-fat content foods as this can damage their liver.

You can shave pieces of the ice cube to feed your fish, one ice cube is sufficient for a moderately stocked 50-gallon tank.
Remember when you’re introducing new foods you should also offer the food they are used to. Perhaps you could offer their regular food in the morning and the new food in the evening. If they take to the homemade food well you can switch over to that. You may want to alter the recipes every few months to give your fish plenty of variety.
