I got total freedom from my parents in the selection of my profession. Now, early on in 1956, when you were 13-years-old, you had made a discovery, blue neon tetra fish. In my childhood, I worked in a pet shop in Zurich, and I found a new neon tetra. I didn’t know at the time it was a common neon tetra, and a red neon tetra, and this looked different, but, of course, I was not a fish specialist, and still very young so I sent it to a museum, and it was described as a new species.
