The Blue Planet, National Aquarium Denmark, Kastrup, Denmark

The Amazon section is home to arowanas, pacus, freshwater stingrays, large catfish, anacondas, pale-mandibled aracaris and more. This part also has an aquarium with a big school–about 3,000–of piranhas. Near the Amazon is the smaller grotto section, with aquaria for cave tetra, various electric fish (electric eel and elephantfish) and other fish found in dark freshwater habitats.
• The African Great Lakes
Exhibits for Lake Malawi, Lake Tanganyika and Lake Victoria. Primarily aimed at cichlids, but also home to other fish such as Nile perch (highly predatory and therefore separated from the Victoria cichlids by acrylic glass), and the section above the aquaria are home to dwarf crocodiles, village weaver birds, and other small animals.
