About the Goatfish
Goatfishes are tropical marine perciform fish of the family Mullidae. Seldom found in brackish waters, they are most associated with the reefs of the Atlantic, Indian, and Pacific Oceans.
The goatfishes are sometimes called ‘red mullets’ as opposed to the Mugilidae, the grey mullets, though that name is usually reserved for the red mullets of the genus Mullus of the Mediterranean. Within the family are six genera and about 55 species.
