I love dwarf shrimp and they are easy to take care of if you start with Cherry Shrimp, or most Neocaridina Varieties.
This is a Fire Red Cherry Shrimp.
Here is a pic of Blue Velvet Shrimp in one of my tanks, these are easy too.
Happy critter keeping, just love what you get and make sure the tank size will be adequate when it is adult size. (And do lots of research!)
