Bioparque Pantanal

In the world's largest freshwater aquarium. The aquarium is part of a bigger museum, but we were primarily here for the aquatic creatures. Amazingly, the visit is free, but you should book in advance as there is a limit. It was not busy when we were there, so our lack of preparedness did not impact.

The focus is on Brazilian freshwater fish, but they had some tanks with samples of species from many other corners of the globe.
