Best Food for Discus

Discus fish are popular with their vibrant colors and interesting shapes. But, have you ever asked yourself what’s the secret to the most vibrant and healthy discus? Without hesitation, the answer is “nutrition.”

A healthy diet for your discus should include various food sources that offer vitamins, minerals, and nutrients similar to what they find in the wild. Also, they will enjoy treats every once in a while of ground beef or mealworms!

In this guide, we will go over everything you need to know about feeding your discus fish and providing them with a healthy diet.

What Do Discus Fish Eat in Nature?

In the Amazon’s murky waters, red discus fish, or Heckel fish, eat lots of plants, crustaceans, and worms, while blue discus fish feed on insects and bug larvae.

In addition, they eat tiny crustaceans, plant material, insects, and detritus that fall out of the surrounding woods during storms.

What to Feed My Discus Fish?

Mature discus fish should have a diet that includes 35-45% protein, while young, newly hatched fry and juveniles require a diet with up to 50% protein to speed up their growth rate.

It’s also worth noting that their diet isn’t only protein, and they require additional fats and vitamins to help them develop vibrant colors.

To have all of the correct proportions of protein, fat, and vitamins, you should provide them with a combination of live, frozen, and dry foods.

What Are the Main Food for My Discus?


Bloodworms are mosquito larvae, and they make excellent food for discus fish. They are high in protein and you can offer them in frozen, freeze-dried, or live forms.

White worms

White worms are rich in proteins and are particularly nutritious for your discus buddies.

Also, they are useful for their conditioning, breeding, and growth since they are high in fats.

To provide a regular food source for your discus, you can culture white worms at home. In order to do this, you should feed the worms bread, oats, and raw sausage mixed with water.

Beef heart

Although the beef heart is a popular frozen food among discus enthusiasts, it isn’t as readily accessible as the other options mentioned above.

This is due to the fact you have to communicate with your local butcher ahead of time and order it in advance to acquire it.

In general, beef heart is a great ingredient for small fish and fry since it rapidly bulks them up and makes them bigger and stronger.

For a beef heart paste, I recommend combining different vegetables, such as peas, carrots, cabbage, and red peppers.

You can scoop it into tiny balls and place them at the bottom of the tank or along the sides.

To add variety in flavor, you can use chicken, turkey, and mutton hearts commonly together with the beef heart.

However, too much beef heart can lead to constipation and other digestive problems. Therefore, only give it to your fish in controlled treats.

Brine Shrimp

Brine shrimp are rich in crustacean oil which is a good source of fats that your discus fish need.

Aside from that, they are high in both proteins which help your discus grow, develop, and stay healthy.

You can culture brine shrimp in your own home. All you need is a big glass jar with thick walls and enough algal growth to keep the brine shrimp alive.

This will provide you with a never-ending supply of food for your discus fish!

How Often Should I Feed My Discus Fish?

The feeding frequency differs depending on the life stage of your fish.

For example, you should feed baby discus from ten to twelve times per day, while juveniles eat five to six times per day.

As for adults, they need two to three meals each day.

Why Should Overfeeding Be Avoided?

Overfeeding can cause water pollution and lead to health problems such as digestion issues, swim bladder disease, and obesity.

Also, food leftovers resulting from overfeeding can foul up the water and make it difficult to maintain good water quality.

After a while, these leftovers will decompose into ammonia and nitrites, which are toxic to your discus fish.

How Should You Avoid Overfeeding Your Discus Fish?

When feeding discus, you can stick to a general guideline of thumb, which is to give them 3% of their body weight each feeding.

For example, a discus weighing 75 grams should eat 2.25 grams of food twice daily.

If the fish doesn’t eat its given food within 15 minutes, you should remove the uneaten food to avoid any water quality issues.

What Are Discus Fish Eating Habits?

Discus fish have grinders in their jaws rather than teeth. They consume food by mouthing it, spitting it out, and then recapturing it before swallowing.

As a result of this procedure, they usually eat smaller and more frequent meals than other fish.

Once discus fish have their fill, they will scan the tank bottom for leftovers and tidy up for approximately an hour.


Do Discus Fish Eat Dry Food?

Discus fish eat dry food and it contains many of the essential nutrients they need. Dry food includes pellets, flakes, powders, and granules.

How to Prepare Quality Beef Heart Discus Food?

To prepare quality beef heart discus food, you should follow some simple steps:

  • Trim, dice, and mince one cow heart to a paste
  • Mince 12-14 large prawns into a paste
  • Trim, slice, cook, cool, and then mince 1 large carrot and 3 broccoli stems
  • 3-4 large fistfuls of blanched, cooled spinach, minced with 3 cloves of garlic to form a paste
  • Mix them and feed your discus according to the instructions

Can Discus Fish Eat Freeze-Dried Food?

Discus loves freeze-dried foods and they are an excellent source of protein, ranking just behind frozen and live foods.

When you offer them to your discus, you should pre-soak them ahead of time to allow for water absorption and expansion.

This will prevent intestinal blockages that can occur if the food is not properly hydrated.

Last Words

With the right diet, your discus fish will stay healthy, grow well, and have vibrant colors.
