Here is a picture. The very front of his shell (by the hole he goes into) is very white. And then the circle swirly part is white too. There is still some yellow, but there is black streaks (like veins) running all over the shell. They are everywhere. He keeps chilling upside down, and I keep thinking he's dead. I take him out and sniff him, and he doesn't smell dead. Then I put him somewhere and he moves. But, each time I look in there he is still upside down, just in a different location. I did see him eating on the moss ball a few days ago (something I've never seen before). It was only briefly, and then he went back into his shell upside down.
