Red-vented Fairy Wrasse

(Cirrhilabrus rubriventralis)

Cirrhilabrus rubriventralis, commonly known as the red-vented fairy wrasse, is a species of marine fish belonging to the family Labridae. Here are some key characteristics and facts about Cirrhilabrus rubriventralis:

  1. Appearance: The red-vented fairy wrasse is known for its vibrant coloration. Males have a predominantly pink to reddish body with a yellow-orange dorsal fin and tail. They exhibit a distinctive red patch on the ventral area, which extends from the throat to the underside of the body. Females and juveniles are less colorful, typically displaying shades of pink to yellow with less prominent markings.
  2. Size: They typically grow to a size of about 8-10 centimeters (3-4 inches) in length.
  3. Habitat: This species is found in the tropical waters of the western Pacific Ocean, particularly around coral reefs and rocky areas with moderate to strong currents. They prefer areas with abundant hiding spots and coral growth where they can find shelter.
  4. Behavior: Red-vented fairy wrasses are diurnal and often found in small groups or harems consisting of a dominant male and several females. They feed primarily on small invertebrates and zooplankton found among coral branches and crevices.
  5. Reproduction: Like other fairy wrasses, Cirrhilabrus rubriventralis exhibits a complex social structure where males establish and defend territories. During courtship, males display vibrant colors to attract females. Spawning involves the release of eggs and sperm into the water column, with larvae undergoing a pelagic phase before settling back into reef habitats.
