Take the bully out of the schoolyard and another quickly takes his place. Only minutes after subordinate male cichlid fish sense an opportunity to become socially dominant, they display dominant characteristics such as changes in color and behavior and increasing fertility. They also express egr-1, a transcription factor that likely triggers enhanced fertility and other long-term dominance traits, according to Russell Fernald at Stanford University and his colleagues.[1]
