need crayfish ID help

[phen30]

Can anyone please help me identify the species of my crayfish?
They started out this red color, but have turned quite a bit more blueish since molting.
Thanks!

Tricky. Any background information on these? My guess would be Procambarus of some kind. Procambarus alleni matches the colour but Procambarus clarkii is more common in the trade and known to throw up colour variations.

Thanks. They came from Carolina biological supply.

Well, you were correct! I contacted Carolina, and they confirmed that they are P. Clarkii. Thanks!

Just so you know it looks like you have a male and female.
