Goldfish Nutritional Requirements: What Do Goldfish Eat?

Knowing what goldfish eat means that your pet goldfish will be able to live as long as possible. The general consensus that goldfish do not live much longer than a year is a very common misconception. In fact, goldfish when properly looked after, can live up to 10 years when in a goldfish tank. While maintenance of a goldfish tank is part and parcel of keeping your goldfish fit and healthy, their food is also an integral part of their well being. Owners therefore need to know what a goldfish needs in terms of nutritional requirements and therefore what they need to eat.

So what do goldfish eat? And what should their goldfish food or goldfish pellets contain to ensure that your goldfish stay fit.

Specifically in terms of feeding goldfish what they need nutritionally, the best goldfish food will differ from other pond fish food or regular fish food as it contains far less protein and far more carbohydrates. Goldfish food will be made with goldfish particularly in mind, so it’s best to choose goldfish flakes or goldfish pellets as a generic tub of fish food will not meet the bodily needs of your goldfish.

The difference between goldfish flakes and goldfish pellets is that flakes will float and pellets will sink. What you choose will be up to you, but you should think about the following things. Firstly, how big your fish are. Pellets tend to be far bigger than goldfish flakes so it may be best to go for flakes if your fish are young. Additionally, pellets are more difficult to remove from your goldfish’s tank which is worth bearing in mind for when you clean a tank’s water.

However, a disadvantage to goldfish flakes given that they float is the fact that goldfish will ingest air whilst eating them. This can be bad for their digestive systems. Plus flakes more easily lose nutritional value when their container has been opened. The air causes them to lose some of the efficacy when compared to pellets.

There are a number of other things that are suitable for feeding goldfish. When in the wild, goldfish will commonly eat a mixture of crustaceans and insects as well as plants and smaller. If possible, look for goldfish food that contains a mixture of these elements. The best goldfish food will contain some form of vegetables, shrimps or even perhaps some bloodworms. Freeze dried foods or even live food can contain these foodstuffs more easily, though live food is more commonly linked with a risk of disease. Frozen food tends to remove this risk factor.

How Much do I Feed my Goldfish?

One important thing to remember is that whatever type of fish food for goldfish you give to your pets, you should never over feed them. It is so easy to do, but it can be dangerous as any surplus amounts of goldfish flakes, fish food pellets or otherwise can stay in the water and make it too dirty for your fish to be able to breathe easily.

Additionally, goldfish have a very different physiology to a human body and one such difference is their lack of stomach. They therefore never feel full so will continue to eat as long as there’s food available. If they eat too much they can suffer from issues such as a swim bladder problems or even blocked intestines. One good way to check if your regular amount of food that you give to your fish is too much is if they leave a long line of faeces after them in their tank.

To avoid this, you can feed a goldfish two or three times a day, but only ever a very small amount. This amounts to tiny little pinches of food. A good rule of thumb is to keep adding these tiny pinches for around a minute and your goldfish should be able to eat all that food in that time and that’s all. Remember to remove any food that has been uneaten in that time so that it does not rot in the water.

Finally, it is a good notion to realise that actually feeding your goldfish too little is far less detrimental than feeding your goldfish too much.

Different Types of Goldfish Food

As previously mentioned, there are a couple of types of standard goldfish food. Goldfish pellets and goldfish flakes are the most popular and have both have their advantages and disadvantages. However, you can also buy specific goldfish food for specific types of goldfish. Bearing this in mind, the market has the option to buy tetra goldfish food, betta fish food and hikari fish food all of which are made with the nutritional requirements of specific types of goldfish in mind.

Other Stuff You Could Feed Your Goldfish

If you are tempted to feed your goldfish meat, remember first to trim off every single piece of fat. These fats from mammals are incredibly hard to nigh on impossible for goldfish to digest so that their bodies cannot cope with these when ingested. The problem is made even worse when the water temperature goes under 15 degrees Celsius at a time.

In fact, the water temperature within a tank can materially affect what and how much a goldfish eats. The lower the temperature, the less the body is able to metabolise the food that you feed them. Water temperature for them is ideal at around 20-21 degrees Celsius or 70 degrees fahrenheit. However, if the temperature goes too low, don’t feed them at all. If it falls below 46 degrees fahrenheit, fish cannot properly digest their food.

Best Goldfish Food FAQ:

Q: How often should I feed my goldfish?

A: Feeding goldfish should ideally happen two to three times a day at most and only ever a small few pinches at a time. If you feed them any more than this you run the risk of contaminating their water with rotting food as well as giving them a painful dose of indigestion which their bodies are not designed to deal with very capably at all. If you are unsure as to what a few small pinches amounts to, think about how big a goldfish eyes are and ensure that the pinch is never bigger than this. Plus, if they don’t consume everything you have sprinkled into their water within one to two minutes, take out the surplus food to protect against dirty water and digestive issues.

Q: How long can goldfish live without food?

A: Whilst obviously not ideal, goldfish that live in aquariums can actually survive for almost two weeks without eating or being fed.

Their omnivore diet and physiology helps them to live so long without food. However, forgetting to feed them regularly is not to be encouraged. While they can survive without food for so long, it does not mean that the time spent without eating is not unduly stressful for them.

That being said, if you are very worried that you are overfeeding your pet goldfish, it is better for them to go without food one or two days a week than to continue as you were. This helps to improve the quality of the water in your fish’s tanks and helps prevent them getting sick.

Q: Can goldfish eat Betta or Tropical fish food?

A: Betta fish food or other types of tropical fish food are suitable for feeding goldfish. The difference between these types of goldfish flakes is that the tropical type is made for warmer waters and colder waters. This results a variance of protein that is included. When fish live in warmer waters, they are far more capable of digesting higher amounts of protein. Given that most of us live in warm houses that naturally keep our goldfish tanks at higher temperatures, Betta fish food is therefore suitable for use as fish food for goldfish.

Q: How do I feed my goldfish when going on vacation?

A: Goldfish are one of the easier pets to deal with when going on vacation given that you do not need to give them their goldfish food daily for them to survive. However, going a few days without goldfish food can actually be fairly stressful for your pets so there are a number of ways you can get around this.

Firstly, look at feeding goldfish with slow release food blocks. They’re fairly inexpensive ways to ensure that your fish get fed slowly for the entire time you are away. They work by being a convocation of safe to eat plaster of paris that have been made with a number of bits of goldfish food. When put in water, over a few days the plaster of Paris dissolves slowly so that these bits of fish food for goldfish, be they goldfish pellets or goldfish flakes, are released into the water. This manner of feeding goldfish is suitable for up to 3 or 4 days. However, there are some slow release goldfish food blocks that can be found that will last up to two weeks. All you need to do is put one in your pet’s tank and remember to lock your front door behind you.

Secondly try using a mechanical dispenser. It is actually possible to feed goldfish over a long period of time with a mechanical dispenser. They are predominantly designed to be suitable for use with goldfish flakes and goldfish pellets.They will release food into your fish’s tank a few times a day thus feeding your goldfish what they need. There will be some fish tanks that have dispensers made by the brand of tank that will release fish food pellets, but there are some generic mechanical dispensers too. It is good practice to use any mechanical dispenser you do buy in feeding goldfish before you go on holiday. Do so for about a week and you will ensure that any teething problems with the dispenser will come to light before your leave your fish unsupervised.
