I used to sell them, and I can still get you a good deal if you need more.

FS: RCS (Red Cherry Shrimp) live arrival guarantee!
They love mosses like
Java Moss, tannins from real driftwood seem to be beneficial. Fine leaved plants are great too... Fast growing plants also keep the water quality good. Shrimp are fairly sensitive to nitrates and nitrites. Stargrass is good.. Combined with floating plants like
Duckweed, it really adds a dimension when the shrimp can walk on the underside of the floating plants. They also need calcium and iodine, but don't worry about dosing anything. Just feed good food- a combination of shrimp pellets, algae/spirulina tabs, fish food, and fresh blanched vegetables like zuchinni, squash, cucumber, etc.. pumpkin is great for bringing out their color.
You have to be careful adding fish, since they'll eat the baby shrimps. crawfish, ottos, snails, and super tiny fish work well though. (Pretty much any fish smaller than an inch and a half will be ok as long as there are hiding places)
evidently you got me talking. lol.
