It hasn't been used for years, but St. Augustine used to mix gharial with muntjac.
I’m not positive, though if I had to guess, probably Reeves. The mix was discounted years ago, so I never saw it in person, though I did see a picture of it when I was in Croc School. I might have a copy of that image in the course materials somewhereI didn't know St. Augustine Alligator Farm, are they Reeve's muntjac (Muntiacus reevesi)
or Indian muntjac (Muntiacus muntjak sensu lato)?
Cleveland zoo has turtles with a gharialWhich species and where were successfully mixed with crocodiles?
Fish, water turtles and small arboreal birds are common, but what else?
