Buyer’s Guide

Types of Goldfish Food

There are different forms of foods on the market to feed your goldfish. The best goldfish food is food as near as possible to what they can find in their natural habitat. This is luckily the aim of most goldfish food providers. They are trying to give captivated goldfish what they can get in nature.

Flakes

Food in flaked form is the type of feed that comes to mind when you say the words ‘fish food.’

As we said,  goldfish food comes in different forms to address the needs of consumers. Therefore, when buying flakes, you should make sure of what it actually contains.

Many flake foods for goldfish are mainly just fillers, and the carbohydrate/protein balance is incorrect. Protein should be high with the carb content lower to ensure your fish gets a healthy and balanced diet.

Pellets

Pelleted fish food is No. 2 on the popularity list.  A significant advantage of pelleted food is the ease with which it can be retrieved once your pet has had enough to eat.

When eating buoyant pellets from the surface of the water, goldfish might swallow a lot of air with the pellet that might cause digestive discomfort.

Ensure that you are buying a well-balanced nutritious feed and not just food with fillers that will lead to malnutrition of your fish.

Frozen Food

Buying frozen food is an excellent treat to spoil your pets. Just make sure that you have ample time to thaw the food before you give it to them.

You must feed them the right amount of food. A good rule of thumb is an amount of food the size of a fisheye every inch of fish. If they leave the food, you must discard it and not freeze it again.

Gel Food

The moistness of your goldfish food is a critical factor if you want to keep good-looking pets. This is because a goldfish’s digestive system is used to eating food that is usually underwater in nature.

Another advantage of gel foods is that it usually contains a more optimal and balanced nutritional value than flakes.

Live Food

Live food is an excellent kind of food to feed your goldfish. It mimics their natural habitat and way of feeding. However, this kind of food can be hard to obtain. It includes brine shrimp, aquarium snails, blood worms, earthworms, and daphnia.

The secret is to use live food sparingly and not as their only means of food.

Veggies and Fruit

Romaine lettuce, spinach, or kale are suitable for goldfish. Just put a whole leaf on top of the water, and that will do the job. Just watch out for kale; it might be a little high in protein.

Grass clippings from a safe place without pesticides and herbicides would be a lovely salad for your goldfish, and they love it.

Peas, pumpkin, and squash can be used to spoil your pets, but it does not replace a healthy diet.

Spoiling them with these foods has only one setback; your aquarium should be cleaned more often to get rid of the rotten plant material.

Ingredients

Goldfish are easy to feed. But, unfortunately, they will eat anything and get sick. It is your responsibility to ensure that they eat the proper diet in captivity for healthy bodies loaded with energy.

Checking the ingredients and understanding a goldfish’s nutritional requirements is vital if you want to take care of your goldfish the way you should.

Good goldfish food must supply your pets with carbohydrates, protein, and fat in the right quantities throughout their lifetime. The fish might have different nutritional requirements during various life stages, which need to be addressed.

We will give you a general breakdown of the different nutrients a goldfish needs to ensure optimal growth and a beautiful pet.

Protein

It is agreed that goldfish will need a higher protein diet of around 30-40%. This will ensure optimal growth and muscle development for the fish.

Young fish need more protein than fully grown fish. So you can feed young fish about 40% protein, while older fish will get all the protein they need at about 30% in their feed.

Proteins also contribute to the development of wens on fancy goldfish. A higher nitrogen percentage will promote a higher hood development.

High-quality protein is required because low-quality protein can cause severe problems. So if you want to feed them a high-protein food of above 40% protein, do it in moderation and not too often.

You can’t go wrong with good quality food that is pelleted or gel-based and made of marine-based protein, coming from whole fish or shrimp.

Some people suggest that sticking to plant-based foods is best as they are easily digested. However, our advice is to mimic nature and give them a combination of both. After all, goldfish are omnivores, feeding on plants and other living organisms in the sea.

Fats

Keep in mind that goldfish in their natural habitat eat a lot of fat during summer to have enough energy reserves for the winter. Then, during the winter, they hibernate, living off the energy stored during summer.

During their life in captivity, the necessity of building up fat for hibernation is not needed because it doesn’t get that cold in a house or aquarium. However, if they have had a high fatty diet, they won’t get rid of the fat.

Most foods contain under 10% fat for that reason. A fat content of between 5% to 10% is recommended for goldfish. The fats of salmon are mainly the fats added to goldfish feed.

Vitamins

Like their human caretakers, goldfish need vitamins, which are in the same range. They need vitamins A, D,  K, and folic acid.

Goldfish provide some vitamins themselves but still need others to be present in their food.

A vitamin deficit is not easy to see with goldfish. However, general signs of tiredness and skin lesions might be indications of a vitamin deficiency.

Generally, most goldfish food you can buy has enough vitamins in the appropriate amounts. However, if you have any doubts, a frozen or live treat can solve the problem.

Minerals

Minerals, just like vitamins, need to be present in the feed. The required amount is minimal, but it will affect the life of your goldfish if minerals are not present.

The goldfish can take the required minerals from the water they live in, but certain minerals like magnesium, iron, and zinc should be in their feed, even if it is minute amounts.

Because most minerals are available in the water, the fish can get it directly from the water, and a mineral deficit rarely occurs.

No Carbs and No Fiber

Goldfish need minimal carbs and fiber in their diet. Therefore, fiber should always be avoided, and if you see the words “bulk” or “ash” on the label, especially in flakes, you should avoid it.

More than 10% of carbs and fiber in a goldfish diet can reduce the uptake of other necessary nutrients to live a normal life.

Carbohydrate content above 10% can cause liver problems for your pets and should be avoided.

Floating Versus Non-Floating Food

It’s not known whether goldfish prefer floating or non-floating food, but both have advantages and disadvantages.

Two factors must be considered when feeding floating food. The first is how greedy the fish is/are and how much competition there is for the food.

If the goldfish is very greedy or the competition during feeding is high, the goldfish will dart for the food and digest it together with a lot of air. That can cause constipation due to the air trapped inside their digestive system. In such circumstances, it will be better to feed the goldfish a non-floating food.

Goldfish are generally greedy fish even in the absence of competition, so it might be a good idea to instead feed them sinking food.

A significant disadvantage is that some food might stay on the bottom of the aquarium, rot, and negatively influence water quality and clarity.

FAQ

How Often Should I Feed My Goldfish?

Feed them between two to three times a day. Overfeeding will cause indigestion and contamination of the aquarium. As a general rule, they shouldn’t be fed more than the size of the goldfish’s eye for every inch of fish, and they must be able to completely finish the food in two minutes.

How Long Can Goldfish Live Without Food?

Although the ideal feeding routine should be two to three times a day, goldfish can live without food for two weeks. If you are away for a while, friends or neighbors can feed the fish once a day. Feeding can also be done once every two to three days.

Can Goldfish Eat Betta or Tropical Fish Food?

Betta fish food is high in protein, and it is not good to feed it to goldfish for any extended time. Goldfish can eat tropical fish food and not die as a result, but the best food for goldfish remains goldfish food.
