From: Unravelling the neurophysiological basis of aggression in a fish model
Correlation between social rank and aggressiveness in male and female zebrafish. The number of aggressive acts performed by each fish towards the other fish of the same sex in colonies with 2 males and 2 females (n = 16 fish per group) was quantified during a 5 min observation on the day of the sampling. Statistically significant differences in aggression were observed between social ranks for both sexes and between sexes (P < 0.001; Two way ANOVA followed by Holm-Sidak post hoc test).
