Buyer’s Guide
The essential thing to understand about food for fancy Goldfish is that this species’s nutritional needs differ from other aquarium fish. They won’t necessarily thrive on a diet that you’d feed Bettas or other tropical fish.
Evolution dictates an animal’s nutrient requirements. Often, their diet must provide what they can’t synthesize in their body. That’s one reason that people — and guinea pigs — must get adequate amounts of vitamin C every day. Let’s define what is vital for Goldfish of any variety.
Goldfish Nutritional Needs
Goldfish are omnivores. That means they eat a mix of plants and meats. They are also opportunistic feeders. They’ll consume what they can find in their habitat, which in this case, is their tank. That’s why it’s critical to make sure that your Goldfish has what they need to survive and thrive.
Macronutrients
Like other animals, fancy Goldfish have nutritional needs that vary with their life stage. Fries will need more of the good stuff to support growth and development. The term macronutrients refers to the top three types of nutrients: protein, carbohydrates, and fat.
Protein is the most important of the three because of its role in body maintenance. It consists of smaller building blocks called amino acids. Some are essential because an organism can’t produce them in their bodies, so their diet must provide them. Others are non-essential because an animal can make them.
Goldfish need at least 29% of their dietary intake to contain protein. However, more isn’t necessarily better. Research shows that high-protein diets don’t make super fish. Instead, the nutrient’s influence on body size and development plateaus after this amount.
On the other hand, carbohydrates aren’t a significant factor. The foods that Goldfish eat undoubtedly will contain some amount of carbs. The percentage doesn’t always put a commercial food in the deal-breaker or dealmaker category.
The correct proportion of fats or lipids is essential, however. Fat yields more energy than carbs. It also plays a role in the fish regulating their body temperature and for the synthesis of other compounds and body structures. Goldfish need about 7-13% fat to survive and grow.
Types of Food
The variety of food types can make choosing a product difficult. There are many differences, aside from the nutritional value of one kind over another. Much of the debate rests with the Goldfish’s feeding style. You won’t have to have them long before you figure out that they are messy eaters.
Available food products feature a broad range of prepared, processed, and live offerings:
Pellets
Flakes
Freeze-dried aquatic animals
Gels
Frozen foods
Feeding blocks
Dehydrated products
Live foods
Manufacturers know that dealing with live insects or aquatic organisms, such as bloodworms, is unpleasant. That’s why you’ll find a host of freeze-dried options, like crickets, krill, and shrimp. Unfortunately, these still have a foul odor.
Live foods are excellent choices if you can handle them because they provide complete nutrition for fish. However, we understand if throwing mealworms or crickets into your tank isn’t an option for you. Another downside is that decaying remains can quickly create an unhealthy environment. The same thing applies to dehydrated, frozen, or freeze-dried products. While they provide adequate nutrition, it’s also imperative to make sure that you’re not overfeeding your fancy Goldfish.
Pellets or Flakes?
You may think that the different forms don’t matter, but they vary considerably from several perspectives.
First, there’s the weight. If your Goldfish don’t eat the flakes right away, they will get waterlogged and sink, or they’ll dissolve and become unavailable to your fish. That can worsen the water quality in the same way that waste does. It decays and converts to ammonia, which feeds the nitrogen cycle.
The other concern is the nutritional value of flakes. When they break down, the vitamins and minerals that they contain disappear. That’s especially true with water-soluble nutrients. They will disintegrate quicker as soon as they hit the water.
Flakes have their place. They are an appropriate form and size for fry and smaller fish. However, that sums up their usefulness for fancy Goldfish.
Pellets are more like adult food for fish that don’t need softer foodstuffs. They are more nutritionally dense and won’t dissolve as quickly as flakes. The good stuff they contain will be available for the fish for longer. That typically makes them the better choice between the two.

Proper Feeding of Your Fancy Goldfish
The best food for fancy Goldfish is a moot point if you don’t feed them properly. There are several things to consider, such as how much and how often to offer them something to eat. Both factors have a direct impact both on the health of your pets and the water quality.
Adding variety to the diet of your Goldfish is an excellent way to ensure that they’re getting the right complement of nutrients. Remember that they are omnivores. Commercial diets will satisfy most of their needs, which is essential to bear in mind if you feed your fish a large amount of animal food.
How Much to Feed Your Fancy Goldfish
The best way to gauge how much food your Goldfish should get is to pay attention to how much they’re eating. Your fish will learn the routine, especially if you feed them at the same time of the day. Since they are opportunistic feeders, they will fill their bellies quickly once the food is available.
Another factor is the water temperature. How cold or warm it is will affect the fishes’ metabolism. That will play a role in their appetite and feeding behavior. Goldfish typically prefer cooler water temps. Another way to gauge the amount is to pay attention to the water quality. Goldfish generate a great deal of waste in any case, but if you’re noticing a large amount of uneaten food in the gravel, it’s time to cut back a little on the food.
Observing their behavior will give you all the information you need. It’s also an excellent project for your children to be in charge of the feeding schedule.
How Often to Feed Your Fish
How often you feed your fish also relates to temperature and metabolism. Being fed once a day should be sufficient to satiate them. Water temperatures can speed things up, including when they’ll get hungry again.
Another way to get a handle on it is to check the tank’s water chemistry. Monitoring the ammonia, nitrite, and nitrate levels will give you the info that you need to make informed decisions about maintenance.
Floating Versus Sinking
Another point to consider is whether the Goldfish food floats or sinks. If it stays at the surface of the water, the fish will gulp air when they feed. That will end up in their guts and can contribute to digestive issues.
Sinking foods are the better of the two options to prevent any problems. Again, the fish will figure out where their food is coming from and adapt quickly.
Conclusion
Based on our reviews, API Goldfish Fish Food is the best overall food for fancy Goldfish. It provides an excellent complement of proteins from various sources in a form that will also help the water quality.
Wardley Goldfish Medium Floating Pellet is a smart choice for a basic food that gets high marks for its nutritional value and affordable price. It fulfills the needs of your fish without breaking the bank.
