Originally slated for completion in June 2014, this ambitious aquarium/research center was still a long way from opening to the public in August 2015. Eventually it will be the biggest freshwater aquarium in the world, housing 263 species of Pantanal fish and other native wildlife in gigantic walk-through tanks holding an incredible 6.6 million liters of water, as well as other freshwater fish from around the world.
The construction of the aquarium has been plagued with problems: it already costs four times more than the original estimate and 80 percent of its fish died during a cold snap because they couldn't be transferred from their holding tanks to the aquarium tanks, which should have been completed but weren't.
