Abstract
The African cichlid fish H. burtoni shows specific behavioral responses to the i.m. injection of testosterone. Approaching and attacking were significantly increased by injections, while 6 other observed behaviors remained unchanged. The results suggest that the injected testosterone affected the control of sexual and agonistic behaviors.
