Halicoeres bivittatus is a species of fish belonging to the family Labridae, commonly known as the Slippery Dicks. This colorful fish is native to the waters of the Western Atlantic, specifically found along the eastern coast of the Americas, ranging from Florida to Brazil, including the Caribbean and Gulf of Mexico.
The Halicoeres bivittatus is characterized by its elongated body and vibrant coloration. It has a distinct pattern consisting of two parallel stripes running horizontally along its body, which give it its specific epithet "bivittatus" (meaning "two stripes"). The upper stripe is typically yellow or greenish in color, which contrasts with the lower stripe, usually of a vibrant blue hue. The rest of its body exhibits variable color combinations, ranging from red, orange, yellow, and even purple.
These fish are commonly found in reef environments, particularly in rocky or coral-rich areas, where they seek shelter and food. They are diurnal and voracious omnivores, feeding on various invertebrates, small crustaceans, and algae. Halicoeres bivittatus can reach lengths of up to 15 centimeters.
Due to their attractive colors, Slippery Dicks are sometimes sought after for aquarium trade. However, they require a spacious tank with ample hiding spots and suitable tank mates, as they can be territorial and aggressive towards other fish. In their natural habitat, they play an important role in maintaining the balance of reef ecosystems by controlling populations of small invertebrates and algae.
