Is this really in Belgium? I mean im not really that surprised, I know of a Russian youtuber with a few smuggled pairs, but if its outside of New Zealand its a smuggled animal
The species is not as rare in captivity anymore as most people think, they breed well in captivity and these are legal animals with documents. The owner keeps them outdoors, the Belgian weather is actually pretty well in the summer. N. elegans can also be found in captivity, the others are extremely rare.
