These physical changes resulted in the ladies equivalent to general male fish. Next their competitive behaviour was monitored. It was found that once these women folk interacted with other females, their aggression higher. In comparison, when the females interacted with males, their aggressive behaviour decreased. The researchers then allowed the feminine fish to engage socially with a group of alternative female fish, who had not been exposed to testosterone. It was found that once the feminine fish stopped receiving testosterone, those that were exposed to the feminine fish still exhibited the male average behaviours.
