The Yellow Goatfish, known scientifically as Mulloidichthys vanicolensi, is a solid yellow fish with a relatively cylindrical body that is found in the Atlantic ocean. The Yellow Goatfish is also known as a yellowsaddle and is starting to gain popularity in the aquarium world. The Yellow Goatfish has facial whiskers that it uses to search for food in the sandy ocean bed. Living in the warm saltwaters of the Atlantic ocean, the Yellow Goatfish is usually found off the coasts of the Americas and Africa. The Yellow Goatfish is not sought after by commercial fisheries as it is rumored to carry the ciguatera toxin rendering it inedible.

The Yellow Goatfish is found in the Indo-Pacific region, possessing a body covered in different colors. The back is red-orange, the belly and flanks are white, the fins are yellow, and the sides show a yellow stripe. During the day you will mostly see this fish congregating in large schools. The body is elongated and cylindrical while the snout is blunt, head flat, and mouth small. It prefers rocky, coral reefs and sandy areas. This fish has barbels or whiskers under the chin; a feature used to separate it from the yellowtail snapper it co-exists with.
