Dennerle Betta Booster is a basic food for gourami, fighting fish and betta, which consume more animal than plant-based substances in their natural environments. Of the more than 30 ingredients, almost 70% are animal-based, such as insect larvae, freshwater shrimp and mussels, and 30% are plant-basedDennerle is taking a brand new approach in feeding aquarium fish. Thats why Dennerle are committed to not adding any fish meal at all to their ornamental fish food during the manufacturing process! Fish meal and other cheap fillers are often added to industrially produced ornamental fish food, the recipes for which are frequently taken from industrial fish farming. Ist aim is a purely economic one: fast growth using minimal materials. Balanced nutrition tends to play a lesser role. In addition to avoiding preservatives, the new fish food is based on the Dennerle biotic system: a combination of prebiotics and probiotics with beta-glucan to regulate digestion and activate the immune system.
