funky looking ghost shrimp

[wildgator25]

i just noticed that one of my ghost shrimp isnt see thru no more. it is a pale yellowish orange. it is acting fine. moving around and eating. i know they turn a pinkish white when they die. could this one be about to die?
i also added some iodine last weekend to my water for the shrimp. do you think it is molting?

Mine seem to get "less transparent" as they grow and age, but I have no idea if it is typical or not.

The ghost shrimp that I have is about 2.5" long so I assume he is pretty old. Right nowhe is not transparent at all and has black lines going along the edge of his plates.
