The Dennerle food for aquarium fishes and…our discus


Slider Food Dennerle Fish food

Dennerle recently propose its foods for aquarium fishes Some may be given to our discus.

The German brand Dennerle had already made noticed with the "Shrimp King" range for shrimp, wanted to stand out from the others available on the market.

It is in my opinion something well realised and I propose you to discover some of these foods for aquarium fishes that may be suitable for our dear discus.


The Dennerle food, more natural for our fishes?

Analysis of Dennerle was that a large number of foods for the fishes living in aquariums were not enough balanced.

Knowing the benefits that existed to give dry food to my discus, but also its limits; I was very curious to discover the arguments of Dennerle

Dennerle made the observation that many brands primarily used as ingredients meals of fishes. This despite diets that differ from species of aquarium fish to another.

Because as you know, There are some fishes carnivorous, herbivorous and omnivorous.

In nature, the fishes have a food very varied including zooplankton, phytoplankton, mosquito larvae, insects, algae etc.…

Those who have read the Bleher Discus will remember the analyses of stomach contents Heiko Bleher done on discus collected from the wild.

Leopard discus

A discus well fed is often a fish in good health.

It is true that for example, our discus require a high protein level in their food, but they do not primarily eat other fishes

Dennerle also made the observation that the ingredients used for the food of aquarium fishes were not clearly specified or detailed on the boxes.

Even the German brand claim that malnutrition on our fishes had for consequences a low grow rate, nutritional deficiencies, sensitivities to disease and much more…

Arguments given by Dennerle were for me more than credible…


Dennerle improve its food with prebiotics and probiotics

To finish convince us, Dennerle has enriched his food with prebiotic and probiotic natural.

Thanks to this, These granulates have many advantages.

Scientifically proven, the Probiotics who are micro-organisms have very interesting effects when they are present in the food.

The fishes have a better intestinal flora and assimilates much better the food. Undesirable microorganisms of transit are reduced, and the organism of fishes become more resistant to infections and stress.


The Prebiotics are ingredients that are not Digested, but which stimulate in the colon the propagation of bacterias that will improve the health of fish (It goes the same for other living creatures).

The Prebiotics for example occur naturally in certain plants.

They improve the transit and the consistency of the feces.

A very interesting asset for a fish like the discus that is easily subject to stress and intestinal infections.

Because you need to know that a food poorly adapted, formulated with low quality ingredients can cause many disorders.

Bacterial infections, virus attacks, parasitic infestations (including flagella) could be originated the distributed food given to fishes!

And it is a problem recurring with our dear discus… (Bassleer G. The new guide to the fish disease, Untergrasser D. Discus health)

Integrate Prebiotics and natural probiotics in the diet of fishes and more particularly the discus is in concequence very advised !

In the french magazine "Science et vie" of December 2012 (Hors Série dedicated to microbes) Renaud Persiaux however explained that the bacteria that are not "native" (born in the digestive system) cannot permanently colonize the digestive tract.

Eat probiotics (Living organisms) give short term but potentially significant effect.

Intestinal bacteria saw pathogenic invaders as enemies. They help the immune system to fight against them.

Maintain the intestinal flora of aquarium fishes is therefore of a great interest to their health…

    Hello Christophe,

    During my last visit to Dennerle, the issue was addressed formats…
    For the "Diskus soft" the biggest size is currently the 1 litre.
    As this is a relatively new product, I think the brand expects to see applications for aquarists.
    If needed, I can ask you this by email?

    Beyond that, There's still I think evoke the notion of weight, not volume. Because for example it seems to me that the Dennerle food is heavier than most of the others for the same volume.
    It distributes less…
