3 brown bars on body that extend onto dorsal (gives appearance of seperate fins) and anal fins, tail fin base dark brown.

In sandy areas and seagrass beds, usually near reefs at depths commonly from 3 - 15 m (10-50ft). It prefers clear waters over sand and rubble bottoms adjacent to reefs. The camouflaged juveniles may be found drifting in the current, whilst adults often dive into sand when they feel threatened - Species of Xyrichtys are called razorfish in allusion to their compressed bodies and the sharp leading edge of their forehead and snout, specialisations for quick entry into sand.
The primary source of food are shrimps. They also eat small fish and molluscs, and planktonic copepods, as well as on benthic prey including amphipods, snails and clams. Their diet is dependent upon the habitat; if they are found in coral rubble sites and sandy flats they feed on plankton and in seagrass they feed on benthos among the grass blades.

Life Cycle
It is a protogynous hermaphrodite (all begin life as females and some of these turn into Terminal Phase males post-maturation). They engage in broadcast mating; the fish quickly swim directly to the surface in pairs to allow the eggs (fertilized externally) to drift through the water via the currents. The planktonic larvae are not under parental care. Spawning takes place during the evening.  While spawning is occurring, the males gather a harem of females and spawn with several of them during the breeding season. The reproductive success relies mainly on the sum of females that travels within the male harem  and this is directly related to the potential of the male to rule over the females or to provide the essential resources that they require.
