Not as flash as the Spotted Cleaner Shrimp, but much more common, Pederson's Shrimp are always a fun find and a challenging photo subject. Their skinny bodies and long antennae make them difficult to get in focus. However, if you can get a bold one and hold your hand still in front of them, they will sometimes hop on your hand and pick off any dead skin around your fingernails.
