For many years I have been visiting aquarium associations, specialist shops and trade fairs and give lectures at their events.

On this website I would now like to offer an overview of my lectures.
Here you will find lectures from a length of about 15 minutes up to two hours, just as it fits into your schedule. You are also welcome to combine several shorter ones to a larger presentation.


With the first offspring of Panaqolus tankei (L 398) began my activity as a specialist author in various aquaristic magazines. The first book projects have also been realized and many more will follow.

about me

For more than 15 years I have been studiing the aqua-fauna of South America, mostly with the fish of the Orinoco and especially of the Amazon and its tributaries. In recent years I have been able to keep and breed numerous dwarf cichlids of the genus Apistogramma and Harnischwelse especially from the genera Panaqolus and Hypancistrus.
I was also able to discover these animals several times in their home biotopes and report about them in my lectures and other publications such as articles in journals and books.
Here you will learn more about my aquarium career.


After traveling to South America for the first time in 2008, where I was also able to visit my favorite country of Brazil for the first time from Suriname, the wanderlust never lets go. Since then I took every opportunity to travel to South America. In this section I will report about my travels.
