@dublinlion When I visited there were a pair, but I know that one animal (a male) died soon after my visit. I did some research, especially on Zootierliste - and ZTL claims that in 2018 to Halle came a male "wild-caught".
This information about Tayto Park is really interesting to me! That first pair came from Magdeburg to Halle in 2017 and a female is supposed to survived. So... it's going not to be a simple question...
