Breeding ghost shrimp?

mine just seam to get little bunches of eggs under there butts, and about 3 weeks after they dissepear little shrimp start appearing. i dont do anything to control, initiate or prevent it, it just happens.

Here is some information from petshrimp.com

This shrimp is not as easy to propagate in the aquarium as most smaller algae eating shrimp of the Caridina or Neocaridina genus, since the Freshwater Glass Shrimp produces free floating larvae that need to be fed micro-food items before they molt into post-larva and assume a benthic (= on the ground) lifestyle. In most aquaria the larvae will not find enough food to develop into their next stage and will starve to death. However, in some old, established tanks with a lot of detritus and decomposing plant leaves on the ground the larvae might survive since there will be microorganisms in the water column. This shrimp does not require brackish water for larvae development as some of their cousins that hail from brackish water and marine habitats (such as Palaemonetes pugio and Palaemonetes vulgaris).
