How many fish constitute a school?

Physics: Publication in Nature Communications

Physicists are also interested in fish – above all when they are researching the formation of structures. A research team from Heinrich Heine University Düsseldorf (HHU) and the University of Bristol (United Kingdom) has examined the schooling behaviour of zebra danio (Danio rerio, also known as “zebrafish”) using methods from the field of multi-particle physics. In the scientific journal Nature Communications, they explain that groups of just three fish already move in a similar way to large schools while, by contrast, two fish display completely different behaviour.
