ghost shrimp carry eggs for 24 to 30 days before they give live birth.
you can try to seperate one after seeing black spots on the eggs that indicate there eyes.
i have found ghost shrimp dont eat there young but the young are very hard to rasie they require tiny food and make sure you have a no fileter runing in the tank or a "sponge" in the inlet to prvent them from geting sucked up into the filter
