Bought 6 Orange shrimp, need info

[garfieldnfish]

I have just bought 6 orange shrimp. They are in a 10 gal with water sprite, pellia, a piece of driftwood, some hiding caves and sand substrate. I have a sponge filter in this tank and it has been cycled for some time with apple snails. I removed the apple snails and the shrimp are the only occupants. I would like to add another shrimp species to this tank. What would be a good mix? One that would not cross breed, get along with the orange shrimp and have the same requirements as far as water perimeters and food goes?
I have Amano shrimp and Singapore Wood shrimp in other tanks and had ghost shrimp before.
I would like to add another, preferably rare species with the orange shrimp. What would you recommend?

I recommend making your choice after reading through the "Shrimp Varieties" section as it has the specifics that will help you make a decission. Best wishes.
