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.
• Evolution and adaption
Aimed at fish evolution and adaption, and contains a mangrove aquarium with four-eyed fish, archerfish, mudskippers and alike, as well as aquaria for Apalachicola snapping turtle and primitive fish such as bichir, gar and lungfish.
