Very few people have had any luck doing this. It's not just salt water, its precise salt water and lots of different "green water" foods,etc. Most people who try this spend way more than amano's are worth just to try and do it and may get a few babies in the end, so if you're willing to setup extra tanks, buy the foods, salt, and spend probably 50-100$ to get a few babies in a year or two once you get the process down, go for it, otherwise don't bother. The transistion period from salt back to fresh is also very difficult to mimic. In nature, the shrimp know when to swim back towards fresh water and do it on there own, at different times as each shrimp grows slights different. Trying to get that down in a tank and know when the shrimp is ready by looking at it, usually doesn't work out.
