Adam seems like you are looking for the same thing as me. The kind of crayfish that don't burrow much.
I remember over 20 years ago I picked up a couple dozen crayfish at a fishing/bait store. They were in an aquarium, just like the minnows. They were big and red and I used them for bass fishing. Anyhow I had about 10 left at the end of the day and I dumped them in my friends pond. Anyhow, I went back fishing a few days later and I couldn't believe it, there was about 10 big holes on shore right in the exact spot I dumped them. They must have come right out of the pond and made holes immediately after I put them in.
