Is that a purposeful mixture or a wild break-in? And what species is that? I've been holding myself back on posting on your photos as I've been exploding with jealousy but I must post here! And to think I was all exciting earlier today when I saw a Florida Manatee, and then I saw your São Paulo Aquariums photos..... ~Thylo
lol Don't be surprised! He'll probably add the two species to the Andean Bear enclosure as well! ~Thylo
I suppose if the caiman is kept well-fed it's not going to bother with the exertion of subduing something live and kicking. But it's a very finely calculated risk!
It is a bit of a risky mix but it is worth mentioning that these species are found side by side in the wild wherever they occur.
