The just hatched out larva is about 1mm, and grows bigger 2 to 3 times everyday. They are ready to hunt other smaller fairy shrimps from the hatching, even each other; but usually they start hunting after reach 3 mm. If the water temperature stays in the higher range, they grow up faster, but the potential maximum size becomes smaller. They begin laying eggs after 18 days from the hatching in the best condition, but normally 30 days. When they start reproducing, they are about 40~50 mm in cold water and 30~40 mm in warm water. And the average size of females are about 10% larger than males. Their average lifespan is 8 week.
