You first might want to consider what parameters the shrimp require.
Second if you have any interest in breeding the species. Sounds like these guys reproduce like amanos... aka need brackish or saltwater parameters for the offspring.
Considering they are a small species, I would recommend a larger species and making sure that you have good parameters for the shrimp you want to keep. Better yet, set up a tank specifically for shrimp so you can better observe and enjoy them.
