I’m pretty sure a hippo and crocodiles could get along there. They do in Africa. The USA considered bringing hippos into the south to fight water vegetation in the southern waterways and providing a meat source. It never caught on and it’s a good thing. Hippos are a bad mofo. There’s a million ways to die in the USA. No use importing anymore. Anywhere IMO.
They live in the same water ways.
That doesn’t mean they get along.
