The sceptic in me feels this research is extremely fishy. This was done on fish. How much of the observed external characteristics of fish can be attributed to behavior?
They are looking at median swimming speed and how fish swim. Calling this "behavior" is misleading. It could just as likely be developmental physical differences.
They watched fish swim and saw that they are more correlated with themselves than others. Everything else is a very fishy narrative. Many people in this thread judge it by empathy with the story instead of what can be reasonably done.
