I just got my first shrimp today -- 7 red cherry shrimp. They're so cool! I have them in my 3-gallon desktop tank. Right now, they seem mainly to be exploring the tank. I have eco-complete substrate, with a fair amount of drift wood and several bright green plants. The shrimps' red shells just pop in contrast to the tank's decor. I can't wait until they breed. Also, I can't wait to get other kinds of shrimp.
