Chlorella vulgaris is a very little (5 - 10 µm) spherical freshwater green alga with a quite thin membrane.
This is opened gently after cultivation. Thereby the natural cellulose- and fibre parts remain intact and support a healthy digestion.
Chlorella contains large amounts of chlorophyll and carotenoids, nutritious vegetable protein with all essential amino acids, valuable fatty acids and important vitamins and minerals.

These characteristics are the reason why it is very good for young fish, can be used as an additional nutrient for fish of all ages and a supplement for self-mixed fish food. And it is also suitable for all other fish (not only herbivores).
