: Collection, animal housing, and experimental procedures employed in our experiments were reviewed and approved by the McMaster University Animal Research Ethics Committee (AUP: 22-03-09). This study was in agreement with guidelines set forth by the Canadian Council on Animal Care (Olfert et al. ). During experimentation, our trials were regularly reviewed by the McMaster University Animal Care Committee. Upon completion of the experiments, fish were returned to their original social groups in their social tanks. Aggression was thoroughly monitored upon the return of the individuals, and no indication of distress or discomfort was observed.
