A lot of resources on the internet will tell you that Discus fish are strictly carnivores, but in reality, they eat a variety of foods in the wild that definitely make them omnivores.
We can help recreate this by choosing foods with the right ingredients.
And to help you do this, I don’t just want to share with you the best foods for discus available, but how you can look at any type of fish food and know instantly if it’ll be nutritious for your discus.
High-Quality Ingredients Vs Low-Quality Ingredients
When you’re shopping for fish food (or any food really) it’s super important to read the ingredient list. And it’s the first few items listed which are the most important as these make up most of the food.
Fish food companies spend a lot of money on flashy packaging and gimmicky bullet statements that try to convince customers that their brand of food is the healthiest.
The problem is, a lot of them spend tons of money on trying to trick customers and not so much on including healthy ingredients in their products.
Major brands (like Tetra and Aqueon), that you’ll see in every store, contain mostly low quality fillers that aren’t very healthy for your fish.
So look beyond the fancy branding and make sure that you’re getting a quality product for your money.
Ingredients to Avoid
Fish Meal
Generic fish meal is made from the guts, bones, scales and skin left over after fish have been filleted for human consumption.
Essentially, and quite literally, it’s garbage.
If fish meal is the only source of protein on the ingredient list, look elsewhere.
Pro Tip: While a generic fish meal is often a junk ingredient, fish meals listed by the name of the fish are generally better quality ingredients that include the meat of the fish. So, a food that contains “salmon meal” is preferable to just plain “fish meal.”
Grains
Grains like corn and wheat are used as fillers in a lot of fish food.
A fish just is not designed to digest grains, at all. In nature, they would never come across something like wheat middlings.
Ingredients like this are hard for a fish’s system to break down so they often just pass through as waste.
It’s fine if there’s a little bit of grain mixed in as a binding agent, but it should not be a major ingredient.
Ingredients You Want
Whole Fish
Whole fish is one of the best possible ingredients to find in a fish food. All of the meat and fish oils are included, making it a great source of protein for your fish.
Spirulina
Spirulina is a blue-green algae (technically a cyanobacteria) that is an excellent plant-based ingredient in fish food.
It is a great source of easy to digest protein as well as a huge variety of vitamins. It’s also a great color enhancer, especially for blue and green fish.
Black Soldier Fly Larvae
Black soldier fly larvae are the juvenile form of the insect Hermetia illucens. This non-biting fly is a great source of protein that’s easy to digest.
Many freshwater fish eat insects and their larvae in the wild, including Discus, making this ingredient an obvious source of protein for fish food.
And the larvae of the black soldier fly have no exoskeleton. So it’s even easier for fish to digest than something like whole crickets.
Whole Shrimp or Krill
Just like whole fish, this ensures that you get the meaty part, not just leftover heads and shells that have been ground up.
A Varied Diet is Best
In the wild, Discus eat a large variety of things, both plant and animal food sources. It’s best to mimic this as much as possible in the aquarium.
Making sure that your fish get a wide variety of foods ensures that they get all of the different nutrients they need to be happy, healthy and colorful.

A Note on Beef Heart
I’m probably going to get raked over the coals by some aquarists for not telling you to feed your Discus beef heart.
I generally do not recommend that you feed fish heavy amounts of protein that doesn’t come from an aquatic or insect source.
Fish are not designed to digest terrestrial protein sources.
Hence, the lack of burger joints at the bottom of the sea.
It has been noted that proteins like beef heart can strain a fish’s kidneys, potentially leading to dropsy and/or other health problems.
Fish are designed to digest aquatic and insect proteins, which put much less strain on their digestive system.
So, I would recommend feeding foods that contain these ingredients, instead of ones that contain large amounts of terrestrial protein.
Which Is The Best Fish Food For Disucs?
When deciding on what food you’ll feed your discus, I would urge you to pick out several foods from this list.
If you rotate foods using two of the pellets on the list, you’re giving your fish a varied, balanced diet with lots of protein and veggies.
Throw in one or two of the “snack foods” for some added protein and you’ll be providing some top notch nutrition that should result in healthy, super colorful fish.
I hope you find this article helpful.
I wish you and your fish the very best!
