1+ month ago: 4ft RTC a-female turned upside down
2-3 weeks ago: same happened to 3ft a-male & to lesser degree to 3.5ft b-female
Nothing's changed, younger 3ft b-male seems ok. The only thing that unites the 3 sick RTC is the origin (rescues from Dayton Ohio Mar 2016) and age ~9yo. a-male and b-female participated in courtship two times this summer.
Water, egg/milt binding, feed causes have been discarded. Must be the bacteria finally got to them, perhaps columnaris. Must get a vet pathology lab service now for sure!
