#4 Tiger Shrimp
Tigers come in blond (pictured) and blue coloring. They are a dwarf breed but can be more difficult to keep. This one is my sole survivor of six.
#3 Yellow Shrimp
Neocaridina heteropoda (var. Yellow) previously called Neocaridina denticulata sinensis (var. Yellow)
#2 Ghost Shrimp
This is a larger shrimp. I would suggest them for aquariums of 2.5 gallons or more. The ghost shrimp is particularly entertaining to watch.
#1 Red Cherry Shrimp
