Hello,
I caught this guy in the St. Croix river under a rock, near Hudson WI! I figured it was a baby of a regular crayfish. But it never grew over 2" long. It has alot of blue on it, with red rings around its pinschers. It also (when it matured) had a bright red spike on its back. Can anybody ID it? Sorry I have no better pics, he was eaten when I had to tear down my small tank and I put him in my larger tank?

that's a cool-looking cray. Unfortunately I can't comment on the ID myself. It's hard to find info on 'natives' since not many people keep them in their aquariums.....
