Creating your own fish food at home can significantly reduce the recurring expenses of buying frozen foods from local fish stores. Providing a varied diet is crucial for fish health, and while rotating commercial foods seems straightforward, it can become complicated when you need someone else to manage feeding while you are away. Discovering homemade Fish Food Recipes can be a game-changer for aquarium enthusiasts looking for cost-effective and nutritious solutions. This guide will walk you through creating your own balanced fish food mix, ensuring your aquatic pets receive optimal nutrition while saving you money.

Making your own fish food involves blending a variety of ingredients to achieve a consistent texture that’s easy for your fish to consume. The process is simple: combine your chosen ingredients while frozen and chop them finely using a food processor. Avoid adding any liquid to maintain the right consistency. It’s essential to chop the food into bite-sized portions suitable for your fish. Pieces that are too large may be ignored by your fish and end up decaying at the bottom of your tank, which can negatively impact water quality.
You can customize the texture of your fish food to suit different types of fish. For larger fish, a coarser blend is appropriate, while smaller fish thrive on finer food. If you keep corals, you can even create a puree-like consistency. Clearly label your food batches based on texture to ensure you’re using the correct type during feeding times. Offering a range of food sizes can help ensure every creature in your aquarium gets an appropriate portion.
Local Fish Stores (LFS) offer a wide array of frozen fish foods, which are great for creating variety in your homemade recipes. To start, consider a mix of frozen options. A good base includes combining cubes from different frozen food packs such as Mysis shrimp, Daphnia, Plankton, Blood Worms, and Krill. Spirulina Enriched Brine Shrimp is also an excellent addition for enhanced nutrition.

Initially, fresh shellfish from a fish deli can be part of your fish food recipe. A mix of fresh seafood can offer excellent nutritional value. Freezing the fresh shellfish for a couple of hours before processing helps in chopping them into appropriately small pieces. However, sourcing shellfish from Asian markets can be a more economical alternative.

Cyclop-Eeze is another beneficial addition to homemade fish food recipes. Available in larger bars or smaller portions, Cyclop-Eeze provides essential nutrients. Break off a section and include it in your food mixture to enhance its nutritional value, particularly for smaller fish and corals.
Alt text: Frozen silversides or smelt fish, used as ingredient in homemade fish food, especially for anemones and eels.
Silversides, also known as smelt, are often used to feed anemones and can be a valuable component in your homemade fish food. These larger fish can be pureed into your food mixture. While anemones might not always respond well to silversides, eels and many fish species readily consume them. Purchasing smelt from Asian markets can be an economical way to include this nutritious ingredient. Freezing them beforehand makes them easier to chop in the food processor.

Nori, or dried seaweed, available in the Oriental cooking section of most supermarkets, is an excellent plant-based addition to your fish food recipe. Tear one or two sheets into smaller pieces and add them to the food processor. For additional enrichment, consider adding a very small amount of Golden Pearls, about three or four Salifert scoops, to your mix.
The image on the right shows a sample of the prepared fish food, ready for feeding. This sample appears slightly watery because it represents the leftovers after packing the bulk for freezing. However, fish typically consume it without any issues, even with the slightly wetter consistency.
Alt text: Homemade fish food recipe portioned into flat ziplock bags ready for freezing.
Once prepared, portion the fish food into separate ziplock bags, press them flat to maximize freezing efficiency, and store them in the freezer. When it’s feeding time, simply break off a small piece, allow it to thaw slightly, and it’s ready to serve. This amount of food, prepared as described, can feed three tanks daily for over a month, making it a highly efficient method for fish food preparation.
Feeding Portions: How Much to Serve
Understanding appropriate serving sizes is crucial, especially when using homemade fish food, as the concentration of ingredients might differ from commercial products.

The image above illustrates sample food portions in serving containers. The larger portion shown at the top is suitable for feeding LPS corals in a larger tank, like a 280-gallon tank, in one feeding session. The smaller portion at the bottom would serve as a good snack for about 25 fish but is likely not sufficient for a full 24-hour feeding period. Remember, overfeeding can lead to nutrient imbalances in your aquarium.

Here’s a close-up view of a single mysis shrimp, illustrating its size. Mysis shrimp are suitable for feeding both LPS corals and fish. Sun corals, for instance, can be fed mysis every few days.
Aim to feed only as much food as your aquarium inhabitants can consume within about 5 minutes. Excess food can contribute to increased nutrient levels in the water, potentially leading to nuisance algae growth.
Phytoplankton is also a vital food source, particularly for filter feeders. Directly squirting phytoplankton at corals or filter feeders like feather dusters or clams isn’t as effective as dispersing it into the water column, as these animals filter feed continuously.
Alt text: Two types of phytoplankton: commercial product and home-grown phytoplankton in a bottle.
Phytoplankton should appear dark green and have a fresh, clean smell. A sour smell indicates spoilage. Refrigerated phytoplankton has a limited shelf life, so always check the expiration date on commercial products. Home-grown phytoplankton is generally good for about a month. It’s important to gently shake home-grown phytoplankton daily to keep the algae cells suspended. If they settle at the bottom, they can die due to lack of light and oxygen.
Feeding phytoplankton every other day is beneficial for clams, copepod populations, and soft corals. If you are introducing phytoplankton for the first time, start with a very small dose, about one-eighth of the recommended amount, and gradually increase the dose over a week to allow your tank’s biological filtration to adjust to this new food source. For commercial products like DT’s Live Phytoplankton, follow the dosage instructions on the label. For home-grown phytoplankton, estimate the dosage based on your tank’s water volume and livestock density. As a reference, about 1 cup of home-grown phytoplankton was suitable for a 55-gallon tank.
Alt text: Rack for growing phytoplankton and baby brine shrimp at home for aquarium fish food.
Growing phytoplankton and baby brine shrimp at home can be a cost-effective way to manage feeding, especially for larger tanks. Producing live food and preparing your own frozen food mixes can significantly reduce aquarium maintenance costs.
A sample feeding schedule could include clipping nori to the glass for tangs every couple of days, adding pellet food to a Mandarin Diner daily, feeding newly hatched baby brine shrimp every other day, and feeding the frozen homemade recipe nightly. Phytoplankton can be added every other day.
Remember to turn off the return pump each time you feed your tank. This prevents food from being drawn into the sump and skimmer, allowing your fish and invertebrates more time to consume the food in the display tank and reducing waste in the filtration system.
