Although it is certainly possible for a Cynops to become sexually mature in a year or even less, females usually take a little longer than males. I doubt she is gravid, you´ll have to keep an eye on her.
If that animal is mostly terrestrial then there is something seriously wrong with it. The shiny skin is a very bad symptom in terrestrial Cynops.
70ºF is not too bad, but for an ill animal it can be a problem. If possible, a cooler temp would be desirable.
I was only asking if they were CB because of the deep red bellies. Generally, breeders don´t achieve such a nice colour. I´m glad they are CB, it´s refreshing xD
Other than cooler temps, and perhaps a preventive salt bath i don´t know what to recommend. The vet would be the best option, of course.
