CrustaGran is a sinking special feed tailored to the needs of fresh water shrimps and dwarf crayfish. CrustaGran contains high-quality proteins from aquatic animals and a high percentage (20%) of valuable algae – Chlorella, Dunaliella, Ascophyllum and 10% Spirulina – for balanced growth and problem-free moulting. Vital vitamins provide for vitality and strengthen resistance to diseases. Natural carotenoids and astaxanthin help to bring out shrimps’ natural colouring in all its glory, particularly in yellow-, orange- and red-coloured varieties. CrustaGran retains its form in water for up to 24 hours. This avoids unnecessary contamination and clouding of the water.
