The humidity was not over 70% for consecutive days in the main enclosure. I think it was probably a bit lower in the QT since there's no substrate in it. I think what folks are saying is that the toads literally dehydrated... but I'd think I'd see some signs of stress if that were the case, prior to them just up and dying. Am I wrong? Can it happen so fast without me noticing? I checked on them at 5:30 and they were dead when I checked again at 10:30.
