Update: I have confirmed it was this shrimp that molted the night before I noticed the white tail (the only other two shrimp in the tank both molted last night). The affected shrimp is moving around more today which appears to be a good sign, however I will post an update with the ultimate outcome for anyone who may come across this in the future.
Update Jan 18: While this shrimp is a little lethargic (I've had a nitrite spike the last couple days) it's tail has been back to normal for a couple of days now. Not sure what that was all about but it's okay now.
