Wild Chocolate Shrimp

Neocaridina freshwater dwarf shrimp are selectively bred to the point where they can keep only one color, such as red or blue.  However, if you put two different colors and allow them to breed, then they'll revert back to their original wild colors, which is brown and clear.  If you breed those offspring, then eventually you'll end up with a Chocolate Neocardinia where their brown color has become the dominant gene.

This girl is currently pregnant but once she releases her eggs, she'll be given her own tank and she'll begin producing a line of full Chocolates.
