Hikari Freeze Dried Spirulina Brine Shrimp, brine shrimp harvested at their nutritional peak which offer a natural source for fatty acids and natural algae. Our gut-loading processing includes spirulina algae to improve coloration and form. An excellent treat almost any fish will eagerly accept. Our pharmaceutical-grade freeze-drying techniques allow us to give you a product as close to fresh brine shrimp as humanly possible. Expect color, texture, and taste not previously available in a freeze-dried food.
