I am Marco Hasselmann and was born in Potsdam Germany in March 1968
The first aquarium fish book I have been reading at the age of 5 years and I had
my first aquarium in the age of 10 years. So most of my fife I’ve been an enthusiastic aquarium hobbyist.
Like many of you my first west African fish I kept was Pelvicachromis pulcher.
From 1986 to 1990 I worked at a professional aquarium fish breeding farm and
since 1990 I started working at the Aquarium Berlin where I became
director and head of employees in 2018.
