A conservation lens
Reef fish are affected by coral loss, warming, destructive fishing, pollution, and the removal of key grazers or predators.
This habitat lens is not a current population-status assessment. Status can differ among regions and change as new assessments are published; follow the reference links and local fisheries or wildlife agencies for current decisions.
