possibly a Procambarus clarkii
Louisiana Crayfish max size 20cm

but more likely a Cherax destructor
Yabby from Australia
max size 20cm temp range 12-22C
Well I can tell you the Yabbies in my dam are a pretty blue with a red claw (red claws) and pet shops do sell these here in Aussie....and does not really look like him....but they are like anything else many types.....not much help..sorry
That's a nice looking lobster. I wish my LFS even supplied lobsters. A blue lobster is actually what they say, blue. I have no idea what it is, but either way, it's still a nice one.
