 What Kind of Food Do Goldfish Eat?

Goldfish are omnivores; in the wild, they feed on insects, plants, crustaceans, and even small fish. While it’s not easy to match their natural diet, you can provide the goldfish with specific foods that mirror their natural diet. 

Most importantly, there isn’t one type of food to meet all of the dietary needs of your goldfish; you need to vary foods to provide a balanced diet for the fish.

Leafy Greens

Vegetables supply goldfish with the fiber they’d usually get in the wild from eating plants. Goldfish have a sensitive digestive system so they need food that’s easy to digest. Vegetables help support their digestion.

Feed your goldfish vegetables, such as spinach, broccoli, and lettuce often, every few days if possible. Note their favorite vegetables and keep feeding them regularly.

Why We Love It

Vegetables are rich in fiber that improves digestion and prevents constipation in goldfish. They are also low in fat and rich in nutrients.

Brine Shrimp

Brine shrimp are small crustaceans found mostly in inland water bodies, but can also survive for a long time in freshwater. Their unique adaptability to water salinity makes them a suitable live food for goldfish in a freshwater aquarium.

You can get the brine shrimp eggs and hatch them or purchase them in a frozen or freeze-dried state.

Why We Love It

Brine shrimp are energy-rich with their protein consisting of 60% of their dry weight. This is why they are ideal for growing, young fish.

The crustaceans have spastic swimming motions that engage your fish’s hunting instincts. Not only is this fun for you to watch, but it is also great enrichment for your goldfish.

Brine fish are also easy to ingest and digest by fish. Given their salinity tolerance, you may use them as goldfish food in freshwater or marine tanks.

Most importantly, unlike many other live foods found in aquarium stores, brine shrimp rarely have diseases that your goldfish can catch.

Peeled Peas

Constipation is a common problem in goldfish and the cause is usually a lack of adequate fiber in the diet. Peas come in handy to help clean up the fish’s digestive tract. Most goldfish keepers prefer green peas.

Why We Love It

Green peas have small amounts of protein, which reduces the ammonia waste from your goldfish. As a result, water isn’t polluted and remains cleaner.

Green peas are part of fish’s sinking diet. In other words, they move to the bottom of the tank, forcing fish to dive there to feed. This prevents the fish from gulping in excess air, which often occurs when feeding on floating foods. Swallowed air can get into the swim bladder, causing buoyancy issues.

Please keep in mind that feeding your goldfish peas may not resolve chronic swim bladder disorders or floating issues caused by poor water quality, internal parasites, or bacteria.

In other words, if your fish has health issues other than constipation, feeding it peas alone won’t help.

Before giving peas to your goldfish, ensure they are peeled. Don’t mash your peas, as they tend to cloud the water.

Bloodworms

Bloodworms are among the best live foods for your goldfish.

Why We Like It

Bloodworms are super digestible and rich in protein, which is crucial for your fish’s growth.


The Different Types of Goldfish Food

Gel Food

Everything that goldfish ingests in the wild is typically soft and moist. Therefore, the digestive system of the fish is used to processing such food.

That’s where gel food comes in handy. Gel food usually comes in powder form, and you’ll need to mix it with water to form a gel. A good example is Rapashy Super Gold Gel Food.

Pros

The food sinks to the bottom, limiting the amount of air that fish swallow as they feed on floating food. Longer term, this can cause buoyancy issues. No air is trapped in the gel food so it reduces air in the fish’s gut.

  • Gel is high in vegetable and protein matter to make your goldfish healthy.
  • The food is also moist, making it easy for the fish to chew and swallow.

Cons

  • Some gel foods may have a little smell after mixing the powder with water, and goldfish can be sensitive to smell.

Flakes

Flakes are thin processed food pieces suited for goldfish in a small aquarium. Flakes float on the surface of the water. 

Pros

  • Fancy and exotic goldfish may find it easier to eat flakes, as they drift slowly on the surface
  • Less likely to stay in the tank and make the water cloudy

Cons

  • May lose part of the nutritional value after exposure to air
  • Flakes float and this may cause swim bladder issues due to the fish gulping air when eating 
  • It’s common for some brands to include filler ingredients in flakes
  • They fall apart as soon as they hit the water surface

Floating and Sinking Pellets

Pellets are dry solid food for goldfish and work effectively when their size is smaller than the fish mouth size. They are classified into two categories: sinking pellets and floating pellets.

Sinking pellets move to the tank’s bottom so the fish need to swim to the bottom to eat the pellets. Floating pellets stay on the water surface.

Floating Pellets Pros

  • The fish has to come to the water surface to feed, which allows you to observe their vigor and health.
  • You can regulate the daily food amount to avoid waste.
  • Floating pellets are not likely to pollute the tank

Cons

  • Increases the risk of fish swallowing air, which can cause problems with the swim bladder

Sinking Pellets Pros

  • Allow fish to dive to the pond bottom and feed naturally
  • They prevent fish from getting swim bladder problems, as your fish doesn’t have to come to the surface and swallow air
  • They dissolve slowly, giving fish enough time to eat them

Cons

  • Fish can accidentally swallow gravel while foraging for these pellets
  • Pellets can stay at the tank bottom and start rotting, which may increase the ammonia content

Benefits of Using Goldfish Food

Here are the top reasons to start using goldfish food:

1. Bolsters Fish Immune System

Some of the best goldfish foods, such as Hikari Saki food, contain vitamins C and E, which strengthen the immune system of goldfish, making them less prone to diseases.

2. Balanced Nutrients for Fish Growth

For goldfish to grow, they need food rich in proteins, vitamins, minerals, and other trace elements. Most of the best goldfish foods come fortified with these nutrients for optimal fish growth.

3. Value for Money

Most of these foods come in large quantities at a small cost. This allows you to save money while feeding your fish for an extended period. A good example is the SAN FRANCISCO BAY Freeze Dried Bloodworms. It comes in a large jar at a great price.

4. Easy to Digest

Constipation can occur easily if your goldfish eats foods that aren’t easy to digest and absorb. However, food specially designed for goldfish is easier for them to digest and absorb. The result is healthy fish and less waste.

5. Cleaner Water

Changing water frequently due to excess ammonia and other waste can be a lot of extra work for the goldfish keeper. And if your fish keeps eating food that makes the water cloudy, they are at increased risk of stress and death due to the toxic waste in the water. By feeding on easily digestible foods, the water won’t be polluted. This means a cleaner goldfish tank for you.

Things to Look For In Good Goldfish Food

Keep the following in mind when looking for goldfish food:

Size

Consider the food size based on the type and size of your goldfish. For example, if you have small goldfish, you want to avoid big-sized pellets that may choke your fish. Choose what fits your fish’s mouth.

Nutrition

You want to ensure the food contains the required minerals, vitamins, proteins, and carbohydrates to boost the fish’s growth and increase their lifespan.

Ease of Digestion

Goldfish don’t have a stomach in the same sense as humans, which is why you need to give them food they can easily swallow, digest, and absorb.

Cleanliness

The goldfish food you select shouldn’t consist of artificial colors or flavors, as they can harm the fish. Additionally, you want to avoid foods that release excess waste and create cloudiness in water.

Goldfish Food FAQs

How Often To Feed Goldfish?

Feed the fish a max of two to three times a day to avoid indigestion and tank contamination.

How many pellets should I feed my goldfish?

Two to three pellets twice per day should work.

How many flakes should I feed my goldfish?

Approximately three flakes. Add small quantities of flakes at a time – for example, three flakes per fish. If the fish consumes it all quickly, add another small amount. It’s recommended that you give them an amount they can consume within four to five minutes.

What is the best time to feed goldfish?

Feed your goldfish at regular intervals so they stay full and energized the entire day. Try to keep the feeding times similar. For instance, if you feed them at 9 am, 1 pm, and 6 pm on one day, put reminders in place to feed them at similar times on the following days.

What to feed a goldfish when out of fish food?

If there’s no fish food, you can use peeled peas, boiled vegetables, or shrimp. Use freeze-dried food instead of live food to prevent the transfer of disease to your fish.

Will goldfish eat dog food?

No. Use specially formulated goldfish food only. Dog or cat food can cause severe disease or premature death.

Why is my goldfish not eating?

There are several reasons for this. First, your goldfish may be bored of feeding on the same type of food daily. Try introducing a variety of foods.

The second reason could be poor water quality. A change of water could be all you need to restore your fish’s appetite.

If they still won’t eat after these two steps, call a fish vet immediately, as it could be a swimming bladder infection.

Why do goldfish spit out their food?

The food particles might be too big, the fish might be full, or in need of food variety.

Can goldfish food go bad?

Yes, goldfish food expires which is why there’s an expiration date on the packaging. If you have dried fish food sitting around for more than three months, you should discard it. At that point in time, even if you give it to your fish, it won’t add any nutritional value.

Conclusion

You need the right type of goldfish food to keep your fish healthy. Feeding your goldfish two to three times a day with a varied diet is optimal.

Try not to underfeed or overfeed the fish. A good rule of thumb is to give your fish food that it can consume within two minutes.

Remember to supplement the diet with leafy greens and hand-fed peas with their skin removed.
