What To Feed Pond Fish? Everything You Need To Know

If you find yourself getting sick of the same old fare for your fish, you're not alone! What we feed our pond fish can be just as important as their environment when it comes to their health. 

But with seemingly endless options, it can be overwhelming to know what's best for our finned friends. Fortunately, we've got you covered with this guide to feeding your pond fish the best way possible. 

Discover everything from the basics of pond fish nutrition to a few tricks and tips for keeping them healthy and happy. 

Quick Review

Depending on the type of fish in your pond, you should feed them a combination of high-protein pellet food, blood worms, brine shrimp, pond plants, and vegetables. Check with your local pet store often for specific recommendations for what type of food would be best for your particular fish species.

Choose Quality Fish Food

When choosing the right type of food for your pond fish, it’s important to choose the best product. Quality is essential when feeding your fish, as subpar foods may contain lower levels of nutrition. They may even potentially contain pollutants that can harm the health of your fish. Generally, look for products specifically designed for pond fish rather than generic aquarium fish food.

High-quality foods can be more expensive but provide higher levels of vitamins and minerals. They will also have an expiration date as these premium foods tend not to contain as many preservatives. 

Some examples of good quality brands would be Cobalt, Hikari, KaiYin, TetraFin Goldfish Flakes, and Marineland Betta Fish Food Pellets.

When attempting to feed your fish more nutritious organic and natural options, be careful to research what you are buying. Natural and organic pet food has become increasingly popular due to their perceived benefits. However, some brands might not have sufficient nutritional value or could contain allergens or additives harmful to the animal. 

Be sure to read labels carefully and select brands that are regulated by professional organizations such as AAFCO and FSMA in order to ensure you are getting a safe and properly balanced product for your pond fish.

Now that we have discussed how to choose quality food for your pond fish, let's move on to discussing the different types of fish food available.

Types of Fish Food

Feeding your pond fish the right type of food ensures that they stay healthy and strong. There are many different types of food available for pond fish, all with their own nutritional benefits. Many of these foods are formulated to meet the specific dietary needs of different species. 

So, before tossing food into the pond, research and select products that are appropriate for your particular pond fish. Here is a breakdown of some of the more popular types of fish food:

Floating Pellets

Floating pellets are one of the most popular types of fish food, as they provide all the necessary nutrition in a convenient form. This type of food usually contains proteins, carbohydrates, fat, vitamins and minerals, as well as added flavoring or coloring.

Floating pellets are ideal for all types of pond fish, as they can easily be eaten at the water's surface while avoiding debris on the bottom of the pond.

Sinking Pellets 

Sinking pellets are a great option for bottom-feeding pond fish that rely on scavenging for their meals. These pellets sink to the floor of the pond and provide an easy meal for these types of fish.

Sinking pellets contain similar nutritional content to floating pellets but also usually have added flavoring or coloring to help attract bottom feeders.

Freeze-Dried Foods 

Freeze-dried foods offer a convenient form of nutrition for pond fish. The freeze-drying process removes most of the moisture content from raw ingredients like meat, plants and algae while preserving the essential amino acids and vitamins that provide optimal nutrition.

Dried algae in rock


This is often a good option for finicky fish that may be difficult to convince with traditional foods like pellets or flakes.

Frozen Foods 

Frozen foods are gaining in popularity among pond owners due to their convenience and nutritional benefits. Frozen foods are typically made up of raw ingredients such as squid, shrimp, bloodworms, plankton and krill.

Frozen brine shrimp in ice


These elements can be a great source of protein, fat and other vitamins and minerals for your pond fish. While frozen foods can provide excellent nutrition, it is important to remember that they tend to contain more moisture than other forms. As the food melts, it could lead to water quality issues if you’re not careful.


Flakes are the classic form of fish food that many people associate with keeping pet fish alive in an aquarium or bowl. Flakes can come in highly varied forms depending on what's included in terms of nutrition. However, generally speaking, they should still provide most, if not all, necessary nutrients for your pond fish population.

It is important to remember that some flake varieties may be high in simple carbohydrates, which can create excess waste from your fish population. So, make sure you pick a variety specifically designed with nutrient-rich proteins, such as seafood or newly hatched brine shrimp eggs, rather than dried cement or grain fillers.

The Debate Over Fish Flakes

The debate surrounding flakes revolves around whether they offer enough nutritional value to keep fish healthy over long periods of time or if they should only be used as occasional treats. 

This debate is due to the flake’s relatively low levels of protein and complex carbohydrates compared to other forms like pellets and frozen foods. On one hand, flakes offer convenience when feeding large numbers of fish. 

On the other hand, their lack of nutrients might hinder growth and reproduction in larger ponds containing multiple species with varying dietary needs.

There’s also a debate regarding frozen foods, centered around whether or not their high water content will cause water quality issues. These issues can include reducing oxygen levels or encouraging rapid bacterial growth resulting in poor health for your pond fish population. 

Supporters argue that frozen foods offer an abundance of nutrients, including polyunsaturated fatty acids. These acids offer multiple health benefits compared to other lesser nutritious versions like flakes or freeze-dried formulas. 

Critics suggest that this convenience comes with too many risks due to overfeeding. This problem can lead to water quality issues too severe for any benefits to outweigh those risks making them less than suitable alternatives overall.

No matter which type you choose, it's important to research each specific product before making any purchases. You must also feed your fish once the food arrives to ensure proper nutrition for each species. 

While store-bought fish food is suitable for many occasions, it’s often best to feed your pond fish naturally. Natural options include insects, worms, and plants. So, let’s break down the best natural foods, as well as how to spot nutritional deficiencies in your fish population when adjusting their diet. 

Natural Foods

In addition to commercial foods, pond fish can be supplemented with natural foods. Natural foods include earthworms, insect larvae, tiny crustaceans (such as daphnia and brine shrimp), and even amphibians.

Insects crawling


As a rule, natural foods are an excellent way to provide nutrition to your fish. The primary advantage of this method is the fact that natural foods often contain more nutritional components than commercially produced food pellets. 

Furthermore, providing natural prey to your pond fish can help stimulate their hunting instincts.

However, using natural prey does have its drawbacks. For example, it may be difficult for you to source a consistent supply of these items. 

Additionally, many of these foods can contain parasites or harmful bacteria that could infect or cause illness in your pond fish. Make sure you know as much as possible about your food sources to avoid these risks.

Ultimately, greater diversity in your fish’s diet should result in better overall health. They do not need to be 100 percent reliant on one type of food, so including both commercial and natural foods is recommended. 

No matter what, make sure to research your fish food, natural or store-bought, to verify that it will benefit your fish, not harm them. 

Commercial Foods

When it comes to feeding your pond fish, there are a variety of commercial foods available on the market. These can include sinking or floating pellets, flakes, wafers and granular foods. Commercial food cannot provide a balanced diet on its own, but it can be an integral part of properly feeding your fish.

Bags of commercial fish foods


Pros: Because commercially made food is designed to meet the nutritional needs of your pond fish, it can be an easy and convenient way to give them the macro and micronutrients they need. Additionally, most commercial foods are designed for certain types or sizes of fish, meaning you don’t have to worry about badly portioned meals for your fish, either.

Cons: Although commercial food has its advantages, some argue that these foods lack variety and don’t offer enough natural protein found in live or frozen food sources. Additionally, many people fear that due to pet stores offering such a wide variety of trout food brands, not all food is created equal–– some may contain dyes or preservatives that could harm your fish.

Overall, commercial foods should form an important part of a balanced diet for your pond fish. That said, make sure to research each brand carefully, and don’t rely on commercial foods all the time. 

Ideally, you can feed your fish live or frozen options and use commercial foods to supplement as necessary. 

The Benefits of Variety

When it comes to healthy fish nutrition, most experts believe variety is the key to a balanced and nutritious diet for your pond fish. However, others argue that introducing too much variety won’t provide any added benefits.

For most species of pond fish, feeding them with different food items in moderation can provide them with plenty of nutrients. Rich, high-grade sources of fiber like algae and plankton will help promote digestive health and nutrient absorption by adding bulk for easier defecation. 

Furthermore, the variety ensures your fish get enough vitamins and minerals along with essential fatty acids.

In contrast, simply offering fish multiple foods may mean they don’t consume enough of one particular item to fulfill their nutritional requirements. In fact, an overly varied diet can also lead to problems like malnutrition or obesity due to overconsumption. 

So, it’s important to consider balance when deciding how much variety to offer each day.

Overall, food variety can help ensure excellent nutrition for your fish. That said, too many different foods could cause more harm than good. So, it’s imperative to understand why variety matters and how to do it properly. 

Feeder Foods

Choosing to feed your pond fish with feeder foods such as flakes or pellets is a convenient way to provide them with their essential nutrients without the hassle of maintaining a live food source. 

Fish food pellets and flakes are quick to prepare, widely available at pet stores, and easy to add to your pond. However, it is important to understand that these foods provide more than just an easy way to feed your fish — certain brands offer benefits for the overall health and well-being of your pond fish.

Before you start feeding your fish store-bought feeders, consider how much and what types of feeders are best for them. Depending on the size of your pond and fish population, the recommended feeding amount can vary greatly. 

Overfeeding can cause an unnaturally high level of light-blue algae from excess nutrients in the water. If you notice this algae in your pond, readjust your feeding routine to prevent uneaten food from settling at the bottom or clogging the filter intake.

Additionally, most commercial-grade feeders do not provide a natural diet for ponds.  They are often packed with fillers and have limited variety and nutrition for balanced meals for your fish. 

A lack of variety in their diet could also lead to sluggishness or bad eating habits like fin nibbling and other potential conflicts between tankmates.

Overall, while store-bought feeder foods are a great way to quickly supply healthy nutrition to your pond fish, it’s still important to understand their limitations.

Live Foods

Live foods can be an important part of a pond fish’s diet. Live food has the advantage of being closer to what they would eat naturally, and some species of fish prefer live food. Live foods are also usually richer in nutrients than most processed formulas.

Pond fish eating live food


One debate among fish hobbyists is the source of fresh live food. Some argue it should come from the wild, while others suggest it be cultivated in a tank by the hobbyist. 

On one hand, taking wild prey can have a severe impact on local ecosystems, as it deprives native predators of a food source and can decrease biodiversity in the area. 

On the other hand, cultivating live food in a tank ties up aquarium space, takes time and effort to maintain, and may not be feasible for those with limited resources. 

Before deciding to feed your pond fish live food from either source, consider your own resources and commitments to avoid potential harm to native ecosystems.

Tips for Feeding Pond Fish

Feeding pond fish can be a tricky undertaking, but with these tips, you'll be able to improve your fish's diet and keep them healthy.

1) Get to Know What Your Fish Eat 

Different kinds of fish have different dietary requirements. Certain fish species need high-protein diets, while others don’t need as much protein. Knowing what type of food your specific breed requires is the first step in providing proper nutrition to your pond fish.

2) Factor in the Quantity

The amount of food given to pond fish is just as important as its nutritional value. Overfeeding your fish can easily lead to water pollution and cause health problems for the fish, such as decreased oxygen levels or soft tissue damage from an accumulation of toxins in the water. 

Avoid overfeeding by only giving your fish what they can eat in five minutes or less. Also, remove any excess food that's left behind.

3) Set A Feeding Schedule 

Establishing a regular feeding schedule for your pond fish helps them stay fed on a consistent basis. It’s crucial to stick to this schedule so that hungry fish will get their meals at the same time each day. 

However, when implementing a new feeding schedule, make sure not to feed them more often than twice per day.

4) Research Any Unconventional Foods 

Many pond owners like to try different kinds of foods to see if their pond fish will enjoy eating them. Before doing this, research the type of food being considered. 

Some options are not suitable for pond fish due to their salt content, or they may have harmful ingredients if consumed in large quantities.

5) Consider the Seasons

During the colder months, most species will eat less often because of their slower metabolism. So, make sure to adjust your feeding schedule accordingly to avoid overfeeding during the winter.

Although these tips can help prepare you for feeding your pond fish, it never hurts to research further or consult a professional. Overall, your fish are important to the health of your pond, so don’t skimp on the details. 

Frequently Asked Questions About What to Feed Pond Fish

What are the nutritional needs of pond fish?

Pond fish require a balanced diet that consists of proteins, carbohydrates, fats, vitamins, and minerals. 

A healthy diet should include quality dry pellets, frozen or freeze-dried bloodworms, daphnia, and brine shrimp. Also, high-quality live foods such as mosquito larvae and small fish can improve their nutrition and health. 

Quality commercial foods are especially important for those fish susceptible to nutritional deficiencies, such as goldfish. 

If you want your fish to enjoy a treat, you can toss in vegetables like peas, spinach, and lettuce. However, do this sparingly, as they can create dirty water, making it harder for your fish to stay healthy. 

What types of food are best for pond fish?

Each species of fish has different dietary requirements, and some may require more proteins than carbohydrates, while others may need more vegetables than animal-based proteins. 

As a general rule, the best diet for pond fish includes high-quality commercial foods like flakes and pellets specifically formulated for the type of fish you own. 

Many pond keepers also supplement their fish's diets with live or frozen foods such as worms, bloodworms, brine shrimp, krill and daphnia. Freeze-dried foods such as krill or bloodworms can also work. 

Some hobbyists prefer to make their own foods by blending various ingredients together in a food processor. As long as you research which types of foods your fish like, it’s relatively easy to keep them well-fed and healthy. 

What are some common mistakes when feeding pond fish?

One of the most common mistakes when feeding pond fish is overfeeding. Too much food can lead to dirty water, both from uneaten food and fish waste. Over time, the water will get polluted, causing health problems for the fish population.

Another mistake people make is providing the wrong type of food. Fish need a balanced diet. If fish are only fed one type of food, they may not get enough nutrients, leading to health problems.

A third mistake is feeding pond fish the same quantity of food all year round. Instead, it is important to adjust feeding amounts based on factors like the weather and water temperature. 

For example, fish may need to eat more often on hotter days than they do on colder days.

What are signs that my pond fish are not getting enough food?

If your pond fish are not eating well, there are several signs to pay attention to. This is why it’s best to feed your fish in the same spot, so you can tell if they’re healthy or not. 

Common warning signs include:

1. Weight Loss - Your fish may be thinner than usual or have sunken bellies.

2. Lethargic Behavior - A lack of nutrition can cause fish to move and swim more slowly, so pay close attention to how active your pond fish are.

3. Algae Growth - Excess algae in your pond can be an indication that your fish aren’t eating enough. This is because algae feed on excess nutrients that result from uneaten food and waste buildup. So, make sure your fish eat everything you provide and clean out any extra food.

4. Decreased Appetite - Fish eat less when the water is colder, but if that’s not the case, they could be sick. Alternatively, you may be feeding your fish too often, so it might be best to skip a feeding or two to see if that corrects the issue.

5. Unusual Fins and Bodies - Unhealthy fins, bumps, lesions, or other discolorations of the body can point to nutrition deficiencies in pond fish which are caused by inadequate feeding.

If you notice any unusual behavior from your pond fish—or signs of poor nutrition—try adjusting their diet accordingly.

How much should I feed my pond fish?

Overfeeding your fish can result in a buildup of waste matter and potentially cause health issues as well as poor water quality. To ensure a healthy diet for your fish, feed them only what they can consume within two minutes. 

Also, don’t feed your fish more than once or twice per day. A good rule is to give the fish only the amount that is equal to one-third the size of their head.

Overall, feeding pond fish is a relatively complicated process, so take your time and do your research. Once you determine the best foods and feeding schedules, pay attention to your fish to ensure they’re happy and healthy all year round. 

With the right preparation and planning, it’s easy to know what to feed pond fish.
