This is the place of the former 'Vissengrot' (fish cave). During the lockdown the zoo renovated it into a new area with seven aquariums and terrariums for different animal species.
- The first is a terrarium for Blue Poison Dart Frogs (Dendrobates tinctorius 'azureus') and Golden Poison Frogs (Phyllobates terribilis).
- The second is a terrarium for Majorcan midwife toads (Alytes muletensis).
- The third is an aquarium for Blue gularis (Fundulopanchax sjoestedti), they are kept with a species of Otocinclus.
- The fourth is an aquarium/terrarium that alternates between growing young of the species in this room.
- The fifth is a paludarium for Blue vampire crabs (Geosesarma dennerle) housed together with Yellow Shrimp (Neocaridina heteropoda 'yellow').
- The sixth is a terrarium for Portuguese fire salamanders (Salamandra salamandra gallaica).
- The seventh is an aquarium for axolotls (Ambystoma mexicanum).
