The wild dogs and lions were good of course, but other than cheetahs there aren’t too many predators afaik. Something like a sloth/sun bear would be very beneficial to a night safari, maybe complimenting Melbourne, meaning Melbourne could excess. Incoming hyenas and porcupines , aardwolf, civets and aardvark are all feasible options. Did someone mention that bat eared foxes were recently added to the import list? Or rejected? If so, those and fennec foxes would also make for entertaining exhibits
