The genus Celpticus is small, comprised of only three species of wrasse. C. parrae are found in the Western Atlantic between 8 - 100m. They live on tropical seaward reef slopes and sometimes on shallow patch reefs. Schools can be found in the midwater feeding on zooplankton (e.g., jellyfishes, pteropods, tunicates).
C. parrae are a smaller species of wrasse, with an average adult size of 22cm. They are purple in color and acquire splashes of yellow on posterior portions of their bodies as they age. They generally have a patch of black on their head and the posterior tips of the dorsal and anal fins.
Their reproductive strategy involves one large breeding male with multiple smaller females. If the male dies, the largest female changes sex and becomes the dominant male (protogynous hermaphrodite).
