Mike Noren from Sweden did a great deal on breeding Amanos
Breeding Yamato (a.k.a. Amano) shrimp

As well as the French guy
Caridina Japonica Online

Here are my projects that failed
Caridina japonica - breeding Vol.1
Caridina japonica - breeding Vol.2

I can get Caridina multidentata aka C. japonica very easily but it is the challenge breeding them
Good luck
Kind regards, Dusko.
