My crappy diagram is below, as I can't photograph these semi-transparent shrimps to save me wee little life:
I am fairly sure that I just bought 7 Macrobrachiums for my 10gal tank.
They were sold to me as feeder "ghost shrimp".
I wanted them as a mini cleaning crew, and my research told me that "ghost shrimp" were peaceful little guys who were generally short lived and delicate. Macrobrachiums are not. 
I am going to start demanding latin names for every single purchase I make, soon. I declare.
