Blue Sexy Shrimp

[Helio]

So with my tank, I have 4 sexy shrimp, and at around 10 pm one of them starts to turn this light blue, and about an hour later they go back to their normal color (which is a darkish red/orange).
I heard that these guys are colormorprhic and can change colors, though I had never heard of them changing to a color like this.
If any of your guys’ sexy shrimp do this please send pictures here to show that because I would love to see them!
Thanks for reading this.

Very cool! I've always wanted sexy shrimp, but having tanks full of wrasses prevented me from getting them. I just recently setup a 20 long with these guys in mind. Now I just have to track some down
