They are displayed in the house Afrika zblizka, opposite to gundis. They´ve been put on display a few says ago and are still shy and hide a lot. They are mixed with African brush-tailed porcupines.
I ´m unsure about their exact determination. A zoo employee said D. arboreus at first and also Zoo Ostrava records their animals as D. arboreus, but now Prague lists them as D. dorsalis on ISIS. I ´ve never seen a tree hyrax before so I just don´t know.
