The purpose of this experiment was to study fighting behavior in male Betta splendens. The study looked at how the aggression level of male Bettas would change in the presence of a female. Five pairs of male bettas were tested ten times: five times with a female present and five times with a female absent. During each test, the males were exposed to each other for three minutes and the number of flares were counted. A one-tailed paired t-test showed that aggression levels of each male betta increased in the presence of a female.
