@Dhole dude Yeah, you're right and there are also echidnas, wombats and koalas in this aquarium, besides many other mammals from all parts of the world...
@noobmaster69
I have to say I agree with you.
Yes, at this moment there are kangaroos in two other brazilian zoos besides SP aquarium, but both of them acquired their individuals from said institution. One of them is Bauru zoo, which is a medium sized zoo, and the other being Animalia Park (not even inaugurated yet) and belongs to the same person who owns São Paulo aquarium. Both of them keep only red kangaroo.
