Reef fish must relearn the 'rules of engagement' after coral bleaching

Mass coral bleaching events are making it harder for some species of reef fish to identify competitors, new research reveals. Scientists studying reefs across five Indo-Pacific regions found that the ability of butterflyfish individuals to identify competitor species and respond appropriately was compromised after widespread loss of coral caused by bleaching. This change means they make poorer decisions that leave them less able to avoid unnecessary fights, using up precious limited energy.
