Hi, I joined the forum in hopes of solving this problem. I have a 5.5 gallon tank with coconut fiber substrate and cork bark ornaments with a plastic plant. The general temp is over 70F and I have a UTH under the substrate on a thermostat to 85F. Humidity is in the high 80's to 100%. I had originally bought six hissing cockroaches from Fluker's this week and one died on the day of their arrival yesterday and another died today. I have a ceramic, kidney-shaped bowl with water and filled with stones to prevent drowning and another bowl with collard greens. Both of the cockroaches that died only had one antenna.. if that has anything to do with it, but I don't think it does. Is there any possible explanation for the dying or is it just travel stress or something? What should I do to keep the remaining four alive?
