Then a free-moving test fish was placed in a third central section and was allowed to swim in-between all three sections. The amount of time the test fish spent in each section was taken down, and then

Even though the test fish tended to school in greater frequency with the section containing a more concentrated number of fish, our statistical analysis showed that there were no significant differences in the test fish’s choosing between the two sections....
