I don't know much about shrimp outside of how to cook and peel them. Is this kind of color change normal? Any new id attempts? I included the attachments for a closer view.

I know of porcelain crabs changing color. After they have molted a couple of times their shell goes from dark green to white with reddish maroon steaks. I'm sure the little guy will be just fine.

He's awesome to watch. You can't hardly see him until he moves because of the new coloration. He'll come flying out to grab anything that I feed. I'm not concerned about his health, just curious.
