5. TetraCichlid Cichlid Crisps Advanced Clear Water Formula

[amazon box=”B000OQRK94″]

It’s hard to make a list of the best food for Oscar fish without mentioning this offering from Tetra. The ingredients in this product are very similar to the flake product described earlier, but the form is different.

As a result, you get the same, world renowned ProCare formula which contains a cocktail of essential vitamins and minerals, to keep your fish happy, healthy and strong.

However, the difference is that this product is in the form of light crisps which are ideal from smaller or medium sized Cichlids, including Oscars. These crisps will float for much longer, and help create less waste.

They are somewhat firmer than flakes, meaning they will lead to less detritus. This is brilliant for you (as the person who has to clean the tank) but is equally beneficial for your fish, as waste inevitably leads to a less healthy aquarium environment.

These crisps promise to create up to 35% less waste than the flake alternative, making it possibly the best food for Oscar fish.


  • Crisps sink very slowly allowing easy monitoring of the amount eaten by your fish
  • High quality ingredients, including patented ProCare formula
  • Available in two sizes, 3.2 ounces or 8.8 ounces
  • Creates less waste in your tank


  • Not designed for color enhancement
  • More expensive than the flake form of the product

Oscar Fish in the Wild

Oscars are naturally carnivorous fish, who originally come from the tropical waters of South America. As a result, to reflect their diet in the wild, the best food for Oscar fish are the products which are filled with crude protein. This can be either naturally sourced or come from processed proteins, though obviously natural sources are favored.

Crayfish, worms and insects (such as grasshoppers) make for wonderful sources of protein to your beloved Oscar’s diet, although this differs a lot from their behavior in the wild.

In the wild, sedentary catfish make up the largest source of protein for carnivorous Oscars, and they eat their prey using a suction method. Obviously, these tendencies are limited in captivity.

Oscars need lots of vitamins to keep their health up, and to boost their resistance to disease. The most important of these is vitamin C, which is why many of the products featured in the top list offer stabilized forms of this vitamin.

Some minerals and vitamins also help to enhance the red color of the fish, which can have secondary health benefits.
