A green shrimp. No, really, it's a green shrimp. They usually appear to be a bright green, but they can also change colour to brown, red, and orange. Their stripe may or may not appear as well. This one appears to be a blue colour, which isn't usual for this species, but it's probably because it had just moulted. This little guy was only about 1/2" at the time this pic was taken.
