Convict cichlids (Archocentrus nigrofasciatus) have evolved to be extremely good parents by protecting their brood. Parental care leads to aggressive biting, chasing, and gill flaring to intimidate predators. In this experiment, we show that environmental factors, such as the changing of temperature in this case, affect a male convict cichlid’s aggression toward caring for his offspring when an intruder is introduced. Male convict cichlids attack more in warmer water.
