Really not much different than keeping tropical fish. Good/consistent housekeeping is required. I perform 30-40% weekly water changes.
Perform a drip acclimation when they arrive. Using airline tubing and a valve or clamp, allow the tank water to slowly drip into the bag/container of shrimp. I usually let it drip over an hour.
You might want to invest in a GH/KH test kit just so you know what these values are. Too low or too high can lead to deaths during and after molting. I add cuttlebone to the tank to increase the calcium content.
Avoid copper for any invertebrates.
Live plants such as moss allow the shrimp something to graze upon.
Place a fine sponge filter over the filter intake.
I keep my RCS at 77-78 F though they are fine at lower temps (low 70s).
