Oh wow, how cool

We never have any here, so this was the first time i've ever seen them. They were big.. size of a hand to a bit smaller, and there was about 5-6 of them in the tank hiding in their little holes. I think they are just regular crayfish, but there was no species name on the tank and ppl in the shop knew absolutely nothing about them. Unfortunately i'm out of tank space for a new tank.. heh

Thanks for the info guys.
