The dorsal and anal fins are rounded. In the caudal fin, however, the ends are drawn out so that they form a sickle. As is typical for doctor fish, the monk doctor fish also has a terminal mouth.
- Fin formula : dorsal IX / 24-28, anal III / 23-26.
Way of life
The monk doctor fish lives in small or large groups over sand and rubble in lagoons or on outer reefs at depths of 5 to 40 meters. It feeds on algae, detritus and zooplankton .
