Males and females engage in seasonal pair bonding and are most often found in pairs on reefs. During courtship, the male and female "dance" around one another above the substrate. The female lays her eggs in a sheet, which she then presses against the underside of the male. The male will then grow skin over the eggs to form a brood pouch. Small pipefish hatch out of the eggs within a few weeks.
