I got my crayfish today. My co-worker brought them in a plastic bag and left it next to my keyboard. They startled me when I sat down to work. Throughout the day they flitted around in the bag in a flurry of activity.

Tonight I dropped the bag in the tank, let them acclimate to the new temp, then released them.

In all there are four of them, a really big one that likes the rock cave, then three other smaller ones that are still sorting out where they want to be. Very cool addition to the tank.

If anyone is looking for some crayfish of their own, my co-worker has lots to go to good homes. Use the contact link above if you are interested, and I can pass your information along.
