The ornate ghost pipefish or harlequin ghost pipefish, Solenostomus paradoxus, is a false pipefish of the family Solenostomidae. The species name comes from the Greek paradoxos, referring to this fish's unusual external features. Ornate ghost pipefish are found in the Western Pacific and the Indian Ocean along reef edges prone to strong currents. They reach a maximum length of 12 cm. They vary in color from red or yellow to black and are almost transparent. They feed mostly on mysids and benthic shrimp. Females carry the eggs in their pelvic fins that are modified to form a brood pouch. Although relatively common, ornate ghost pipefish are very well-camouflaged and difficult to find.
