This species manifests apparent permanent pairing and monogamy. During most of the observation period, a single pair swam slowly in a side-to-side orientation at a height of 25 to 75 cm above the reef. No conspicuous courtship displays were evident, nor was there any evidence of sexual identity, i.e., the female was not obviously swollen with eggs. Shortly after sunset, the pair ascended in a broad, shallow arc off the bottom, traversing approximately 7 to 10 m while ascending to a height of 2 to 3 m. As the pair ascended, each angled its body slightly, with their venters in close proximity, if not actually touching. This position was held throughout the peak of the arc, with the pair diverging on the descent. Other pairs in the area were seen making similar arcing movements elsewhere on the reef at approximately the same time. It was difficult to see if there were gametes released in the event. There was no interference between pairs during spawning.
