Goliath Frog is an interesting case.
Seems like Chester Zoo had one in 2014, it is talked a bit about here but not much info. Zootierliste also mentions it under former holdings. A few other European Zoos seem to have had them into the early 2000s. Now they are all gone.
San Francisco got them according to their website:

If anyone knows more about that then I am very curious.
Many sources say they don't do well in captivity, yet this is stated on Wikipedia:
''The goliath frog can live up to 15 years in the wild.
In captivity, they can live up to 21 years. It is preyed upon by snakes,
Nile crocodiles,
Nile monitors, and humans, among other predators.''
If that is true, then someone must have been successful with them
Bring me all your Goliath Frog gossip.
