Plankton food for all ornamental fish. The 2-3 mm Calanus zooplankton feed on single-cell microalgae that serve as "vitamin factories" in our planet’s oceans, making them rich in nutrients and full of essential amino acids, proteins and unsaturated omega-3 fatty acids.
Calanus is the nutrient base for the gigantic schools of herring found in the North Atlantic, and is the most important link in the food chain there. Naturally occurring carotenoids, in particular astaxanthin, help produce vibrant colours.
Fish love the taste of Calanus, and even tricky fish caught in the wild can become accustomed to dry food using this natural food. Calanus FD organic is a suitable supplementary food for all types of aquarium fish.
Calanus FD is produced by freeze-drying, which preserves nutrients and aromas, and therefore has many advantages over commercially available frozen food.
