Brine shrimp deserve to be considered by the tropical fish industry as the single most important food item in the whole world. This is due to the fact that brine shrimp contain an unbelievably high amount of energy. If not for brine shrimp, the tropical fish industry might not be what it is today. To help larval tropical fish have a good start, newly hatched brine shrimp is used by almost all individuals who breed tropical fish at home as well as at nearly all fish farms.
