Tilefishes are mostly small perciform marine fish comprising the family Malacanthidae. They are usually found in sandy areas, especially near coral reefs.
Commercial fisheries exist for the largest species, making them important food fish. However, the U.S. Food and Drug Administration warns pregnant or breastfeeding women against eating tilefish and some other fish due to mercury contamination. Exceptionally colorful smaller species of tilefish are favored for aquariums.
