Fish and humans are similiar when in risky situations
 
New research carried out by scientists at the University of Bristol has shown that despite individual animals having their own personality, this gets suppressed when they make decisions together in a group.
Dr Christos Ioannou and his colleagues from the School of Biological Sciences tested three spined sticklebacks (the UK's smallest freshwater fish) alone and in groups of ten.
They found that just like in humans, braver individuals led the groups, and that the fish stuck together when making a risky decision.
