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 guppies2 or convict cichlids3 that have been released by private pet holders.
