Yes, that's right. This is one of the prettiest enclosure for marsupials have seen. They are four individuals there (two normal and two black color morph).
This does look very nice, and of a good size based on the quoll in the corner. Are all four kept together?
Is this in the house that used to house the ferret-badgers? It looks a lot like it could be the very same enclosure.
No, it is not. The Ferret-badgers used to live in the Kangoroo House which is now the Venomous Snake House. The Quolls live inside the historical Deer House, which one is located an other part of the zoo.
