Ghost shrimp not ghostly

[trochilids]

Hey folks,

A couple of my six ghost shrimp in my 40 gallon tank have turned off-white with greenish legs. Their bodies in particular look very odd and are no longer see-through. The other four are normally "ghostly." I was gone for 10 days and came back and found this... Are these blonde guys getting ready to "shed"? Or is something else amiss?

Thanks!

They are going to moult I think.

They may be ready to molt. "Ghost" shrimp coloration can vary widely though since their are quite a few shrimp sold as "Ghost" shrimp. I've seen hues of blue, yellow, green, and one that had a purple tinge.
