There are different kinds of glass shrimp--some fw, some brackish, some full sw (and they all look almost alike). I've kept and raised the fw kind, which only live 12-18 months on average. First, put your female in a tank of her own, use water from the fish tank to fill so she isn't shocked by any parameter changes (if she's been in a heated tank, you might have heat hers now too). Put in some floating plants that have been sitting in the sun growing infusoria and rotifers (which the babies will eat). Keep the tank clean. She'll carry her eggs under her tail for about 3-4 (maybe 5, depending on the temp of the tank) weeks. About the time the eggs are ready to hatch, you'll be able to see eyes in the eggs. When they hatch, they will go through a larval stage where they hang suspended in the water with very limit mobility (so use a seasoned sponge filter and set it as low as you can) and have to catch their food. I've always just left the mother in there (but I keep my shrimp mostly in fishless tanks) but you can remove her once all her eggs are hatched (and they probably won't hatch all at the same time, hatching might go on for 5 days or so) back to the original tank. The babies will float around mid-water for about 2 weeks eating and then they'll molt into their shrimp-shape (small though) and they'll hide in the mulm and you won't see them for awhile. Eventually, if they survive, they will molt continually and grow and be just like the big ones. You can feed the babies (even in their floating state) small Golden Pearls which will diffuse in the water where the floating babies can reach them (babies won't be able to get anything floating on the water surface), or new born and well rinsed baby brine shrimps. Don't over feed or you'll have to clean the tank which is hard to do with babies uncooperating. It's not hard, keeping the water clean (no ammonia, no nitrites) is hte hardest part. Once the babies molt into mini-shrimp, you can run a filter but put a sponge over the intake pipe. Or you can just keep running the sponge filter at a higher rate.
