mulloidichthys vanicolensis

The goatfishes are the grubbers of the reef. They use their chin barbels (long finger like projections under the mouth) to probe the sand as they search for the mollusks, worms and crustaceans that they feed on. While many goatfishes occur singly, the yellow-striped goatfish is a school-forming species. (Photograph: Mark Snyder)
