Besides being a playground for shimmering schools of Congo tetras, the exhibit is also home to the giant freshwater puffer. Also known as the mbu, meaning ‘rock’ in some African dialects, a full-grown adult looks just like a rock in the river.
Look out for the distinctive broad snout of the African dwarf crocodile, the world’s smallest crocodilian species. It’s usually relaxing at the far right corner of the exhibit. See if you can spot it!
