This is a relatively new fish food, and one enthusiastically endorsed by many keepers of demanding species. It is especially useful in delivering rich nutrients to finicky eaters, fishes with small mouths, larval fishes, and in enriching mixed fish rations.
According to the producer:
Cyclop-eeze® are a selectively bred, biologically engineered microorganism which cultured in a pristine arctic lake.
Cyclop-eeze are a decapod (10 legged) microscopic crustacean that are instantly characterized by their intense blood-orange coloration. In fact, Cyclop-eeze contain the highest known concentration of the fundamental and critical biological pigment Astaxanthene, accounting for their striking coloration.
Complimenting this are previously unknown levels of the Highly Unsaturated Fatty Acids (HUFA's) especially those of the famed "omega-3" family. These highest levels of omega-3 HUFA's are essential for larval aquaculture applications and typically exceed forty times (40X) those obtained from hatching the highest quality Artemia eggs.
The Cyclop-eeze are voraciously consumed by all animals because they are very rich in the attractant Betaine as well as other palatability factors. Experimental test results at leading academic institutions indicate that the Cyclop-eeze are highly stimulatory to the immune systems of most aquatic animals thus leading to greatly improved survival.
