No, mahi-mahi (also known as dolphinfish or dorado) is not a bottom feeder. Mahi-mahi are pelagic fish, which means they primarily inhabit the open ocean and are often found near the surface, rather than near the ocean floor. They are known for their vibrant colors and are typically found in warm oceanic waters around the world. Mahi-mahi are carnivorous fish and primarily feed on smaller fish, squid, and other marine organisms found near the ocean's surface. Their diet and feeding habits are characteristic of predatory fish, rather than bottom-dwelling or bottom-feeding species.
