Bad news. The big male seemed to be doing better. He had started eating again and the bumps seemed to be getting smaller. It stayed at my parent's place in a barn, where it had a large (1000 liter) plastic container. I wanted to move it to my shed, but during transport it died. I can only think of stress. It was transported in a large styrofoam container filled with moss without any water. The trip took only 40 kilometers. I put it in a large tank just to be sure it didn't play dead, but after a while it got rigor mortis. Sad day. It's also sad that my other 3 animals are females.
