Once you enter the air-conditioned interior, Araipamas (the world's largest freshwater fish) can be seen in a medium sized tank in front of the entrance door.

The complex is divided into three sections:
Tropical Rain forest, Temperate and Sub-Antarctic. The Sub-Antarctic was probably the most popular section– the ‘penguin-arium’ houses cute little rock hopper and black-footed penguins that cause quite a few people to crowd around the exhibit to get a good look.
