Sne is holding her eggs in her swimmerettes and stirs them constantly so they are oxygenated. There are some really great pictures in the photo gallery (not mine, darn it) that show the eggs in amazing detail. Unfortunately they won't turn into shrimplettes without brackish water.
Why not? Ghost shrimp do well in fresh water. Mine is an Amano and they are a little different. If you have a male and female you should get babies at some point. Don't despair!
