Nicole: If you are serious about raising the pepperming shirmp you need to get the book "How to Raise & Train Your Peppermint Shrimp" by April Kirkendoll. It is a hobbyist guide to raising the shrimp from egg to adult. It's a small book that makes for some interesting reading as the author throws in some humor. They are not that difficult as they will eat artemia from the start. Time consuming though.
