Halichoeres rubricephalus, commonly known as Red-head wrasse, is a species of marine fish that is endemic to the Flores and Banggai Islands in the western central Pacific, specifically Indonesia. It was first described by Kuiter and Randall in 1995. The Red-head wrasse is known for its striking appearance, with a bright red head and a contrasting blue-green body. It can grow up to 5 inches in length, making it a relatively small species of wrasse. A minimum of 50 gallons is recommended for them with lots of hiding spaces and live rock.

Halichoeres species are known to be foragers that feed on small benthic invertebrates and algae. They are known to pick at rocks and substrate in search of food. In captivity, Red-head wrasses can be fed frozen Mysis and Artemia, and are generally considered to be relatively easy to feed. These wrasse are reef compatible with caution as they may pick on invertebrates and other wrasses with similar colors and body shape.
