sera San Nature is the color food without dyes and preservatives for all ornamental fish eating at the water surface.

Color development is enhanced exclusively by the natural ingredients such as Haematococcus algae rich in astaxanthin and Krill.

At the same time, they also enhance acceptancy, liveliness and readiness to spawn of the ornamental fish. The flakes keep their shape for a long time, and do not cloud the water.
