Since earliest youth contacts to the aquaristic hobby. With about 10 years first own aquarium. In the 1990s break. 2002 Re-entry into aquaristics. Besides keeping and breeding South American fish, I am also interested in their origin, so that I have been able to make several trips to South America. Furthermore, I have been active for years as an author and lecturer, thus passing on my acquired knowledge. Through my company (ATS-EDV-Service) it was possible to combine the pleasant with the useful. As I had a lot of good fish pictures anyway, it was obvious to make them available to other people and to work together with photographers I know.
