At least some of the imports over the last several years have been shown to have chytrid. The chytrid in at least one zoo accounted for 100% mortality of the salamanders post importation. (and if not treated can pose a threat to a person or institutions' entire collection) In addition, this species is typically imported with little to no fat reserves so the first couple of good meals causes refeeding syndrome and they can die.
If you search the archives you will see that this species has been discussed on here a couple of times.
Typically though, within 6 months of importation, they drop thier tails and die within a couple of days.
Once you scan through the archives if you have any further questions, please feel free to ask.
