Now, it is time to get to know more about the Oscars’ diet and preferences when it comes to their nutrition.

You cannot give the same kind of fruit to an animal as you give to a human being. This is true for aquatic organisms as well. Life below water is very diverse and each kind of fish has specific nutritional requirements. To understand these requirements, it is necessary to study the species that has that particular requirement.

A Little About Oscar Fish  

Astronotus ocellatus is the scientific name of the fish commonly known as Oscar. This fish comes from the family of cichlid. It is also referred to as tiger Oscar, velvet Oscar and marble cichlid.

The natural habitat of this fish is the tropical region around South America. This region consists of the Caribbean Sea, the Atlantic Ocean, and the Pacific Ocean. This fish is available as an edible for humans throughout the world. The Oscar is up to 45 cm long and weighs around 1.5 kg.

An interesting fact about this fish is that it can change its color. This trait prevents attacks by the predators around it.


In the ocean, an Oscar has plenty of options regarding its diet. It relies on a variety of insects and crustaceans. It eats many types of living beings as well.

Although, eating meat is not always good for them, but you just can’t take care of them in the ocean. However, we are going to talk about the aquarium feed for pet Oscars.

There are many types of food available commercially, but it is best if you choose the feed that is designed specifically for the cichlid family. A large variety of pellet food is available in the market that comes in different sizes, concentrations and chemical compositions.

There are lots of varieties because the needs of a juvenile and an adult Oscar are different. Following is a list of living organisms that an Oscar eats:

  • Mealworm beetles (mature mealworms)
  • Mealworms
  • Mussels
  • Plankton
  • Prawns
  • Shrimp
  • Small fish

It might seem like a good idea to feed them living things all the time but actually, it’s not. You have to be careful about the type, quantity and frequency that you are feeding your pet Oscar.

Overeating or frequent feeding can be dangerous for them. It may destroy their appetite and they may reject any other type of food offered to them later on.

While living things contain a lot of nutrients, consuming excessive nutrients might make your fish fat. Apart from being harmful to the fish, it might increase maintenance work for you. You will have to change the water in the tank more frequently. In addition to that, feeding living things can be expensive as well.

Fruits that contain vitamin C such as oranges and lemons can be a positive addition to their food. Oscars can also eat bananas, watermelons, cucumbers and green peas.

Out of all the fruits, green peas are natural lubricants and they can help cure constipation caused by bloat. It is safe to feed your pet Oscar with fruits but it is important to get rid of the seeds inside the fruit. This is crucial because seeds can be hazardous for an Oscar’s health.

Although fruits are safe and healthy, it has been observed that Oscars don’t like fruits. They tend to hesitate and only a true fish enthusiast can make them eat raw fruits.

It is better to feed them in the form of pellets. Each pellet should include the right amount of proteins, carbohydrates and vitamins. So the proportions should be correct. While buying the pellets, do read the ingredients. Select the pellets with a higher concentration of algae or an algae meal with “spirulina.”

A lengthy list of supplements won’t hurt your fish especially vitamin A and C. Astaxanthin is the substance that helps bring out the prominent red color in an Oscar. Look out for this ingredient in pellets. Shrimp shells also contain Astaxanthin.

So, if either of these items is present in the ingredients list, you are good to go. Floating and sinking, both kinds of pellets are available for pet Oscars. However, floating pellets should be preferred because the fish might swallow gravel in an attempt to eat the food that has sunk in its tank.

Many Oscars lose their life every year due to this problem. One of the major drawbacks of pellet food is that it is very dry. It can cause constipation and bloat which ultimately leads to death. Some pellets do contain probiotics that help minimize this risk, but it would be much better if supplemental food has a higher concentration of moisture.

As it turns out, feeding a fish is not an easy task, and you have to take a lot of measures. Oscars can eat fruits such as oranges, bananas, watermelons, etc. While fruits are healthy for fish, they do not like to eat them.
