I brought these babies from Oregon the first of September. They were doing so well. I brought them 450 miles with no losses. I set up the new 20 a week ago with old water, new sand and many shells. I checked the water perimeters daily and Yesterday everything was a go. So I moved them, in their shells, to the new tank, Yesterday morning. They seemed fine. They came right out, checked out their new digs. Everything looked ok. The light went off at 1pm as per schedule and back on at 5pm. They were either dead already or on their last breath. I really don't know what happened. I just feel sick and stupid. What could I have done? :violent: ph8.4 ammunia 0, nitrites 0, nitrates 0. and the water was de-chlorinated with Amguell. I have a sponge filter and a penguin 150 on the tank. It was still a little cloudy,but that's never been a problem before.
