Goatfish are a family of fish (Mullidae) found in tropical and subtropical waters worldwide. They are named for the pair of barbels (whiskers) under their chin, resembling a goat's beard. These barbels are sensory organs used to probe the seafloor for food, like small crustaceans and invertebrates. Goatfish are often brightly colored, making them popular in aquariums. They are bottom feeders, constantly searching for hidden meals. Think of them as the ocean's bearded prospectors, always seeking treasure. They keep the seafloor tidy.
