I'm hoping 26 crayfish can't mess up the pond too bad. I will find out what that sign above the tank said. Thanks for all the info on northern crayfish. I'm hoping thats what they are, but the shop owner didn't inspire a lot of confidence in these crayfish even being what the sign said they were. He said the crayfish were somewhat of a sideline for the fish supplier he gets his fish from. They happen to come up in the nets etc..
He's the only "licensed" seller I could find though. (In state..)
Thanks again for all the info. I can't imagine these guys harming the pond with tunnels. Too much rock and packed clay, and the dam is pretty wide. (Old pic, from winter)

9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
