I wouldn't want to commit using those photos, and I don't know what a healthy shrimp of that type looks like to be honest. I would expect some discolouration from shipping etc, but that same thing could also have made them sick as you say.
When I looked up pictures on google all the shrimps were a cloudy light brown so they are naturally cloudy and maybe just lost some colour in transit, see if anything changes in a day or two?
Can you remove them and keep them separate for maybe a week, even in a bucket etc, using tank water as they have acclimated to that already! Of course catching and moving them again will stress them even more............
Hello everyone, i got 5 C. typus at 7:00 p.m. (UTC+8). They were stuck for a day or so from shipping before i received them and i got worried some of them would've died. In some kind of miracle 4 of them survived. When i got them acclimated to my tanks i took some time to observe them and i noticed some of them had this pale white look on their bodies and immediately got worried because i know i could endanger my other shrimp. Sorry for low res pics i'll try to get more shots tomorrow
Here are two pictures of one of them:
