Here is some more info: http://www.thefishwiki.com/Amano_Shrimp
Amano shrimp are very very hard to breed, I have been trying for some time and have yet to bring a single batch to maturity. Cherry Red shrimp will breed in your tank so even if you have the rare fish attack, they can surivie given proper hiding conditions.
Amano shrimp are lager then Cherry Red also, and therefor are more compaitable with more fish. Many fish can can eat a shrimp, don't becasue of who knows why. I used to keep shrimp in my community tank and they did fine, untill I added puffer fish.
But like they said, expensive snack.
If you want some, almost, free Cherry red shrimp (http://www.thefishwiki.com/RCS
