Mantis Shrimp's tail turning white?

[llama roadkill]

Hey guys.

 

It's gonna be very hard to get pics, but I've noticed that my mantis' tail end seems to be getting a little bit whiter than the rest of his body. Anyone know what this could be?

 

Thanks,

Hopefully not shell rot? I think it's a common ailment for mantis shrimp and not good news.
