sera Shrimps Nature is the staple food consisting of gently manufactured granules without dyes and preservatives for all shrimps in fresh and marine water. The balanced composition with ingredients close to nature, such as spirulina and alder cones, provides everything the shrimps require for healthy growth and safe molting. Fertility, splendid coloration and disease resistance are enhanced in a directed way. The sinking small granules keep their shape for a very long time, thus allowing the shrimps – according to their natural feeding habits – to grab them and slowly graze them off without polluting the water.
