The stream Gillbach is a tributary to the Erft in North Rhine-Westphalia, Germany. With a length of 28.5 kilometres it flows through the cities of Bergheim, Grevenbroich, and Neuss. At the source the Gillbach provides cooling water for the Niederaussem Power Station. As a consequence, the stream is much warmer than most other streams in Central Europe and even hosts tropical fish species like guppies^[2] or convict cichlids^[3] that have been released by private pet holders.
