The female carrys the eggs like normal freshwater shrimp but for 5 weeks, then they hatch into larvae and get released over a few days. The larvae swim around head down tail up for about 2 weeks before growing into shrimplets. They have little legs that flap around very fast, they are just up from their eyes on either side of the body, if you look carefully you can see the blur of the movement.
These guys live for 20 years, don't need water changes and eat maybe one food pellet a month if at all (they eat algae and biofilm that grows naturally). truly amazing shrimp.
