There's a guy in the CCAC that's currently trying to breed them locally, he might give you some insight. I know the eggs require brackish (half saltwater) to hatch, and then you need to gradually make the water more and more fresh as the shrimp grow up. I don't have specific instructions, but he might be able to tell you more. PM me for his email or ask on the CCAC forum - http://www.circlecityaqclub.org/modules.php?name=Forums
