There is a large breeding area in the center of the building. It is planned to breed especially the fish species which live in the cold upper parts of the Danube river and which are almost extinct today. In order to connect the coldwater section of the Lech river with the tropical rain forest, a touch pool with domesticated carps and a circular tank for schooling fish are planned. Between the rain forest tank and the coral reef is a tide pool, just like in nature. This tank is divided and the water is pumped from one part into the other so visitors can see the low and the high tides together.
Visitors then enter an acrylic tunnel and walk through the coral reef to the exit again.
Because of the poor quality of the ground the construction of a basement is impossible. Therefore all the technical installations must be on the ground floor or over the tanks. Large glass panes enable the public to look through into the large technical area and from the zoo side they can look through large windows into the breeding station. The start of the construction is planned for the end of this year. Of course, for our own Zoo-Aquarium, we are also planning another annex building for sharks, larger coral reef fish, sea turtles and a large natural mangrove swamp.
