Marjorie's Wrasse

Geographical Origin and Habitat: Cirrhilabrus marjorie is a marine fish native to the Western Central Pacific Ocean, specifically endemic to the coral reefs of Fiji. It inhabits steep outer reef slopes and deep rubble fields, typically at depths between 20 and 50 meters, where the water is clear and swept by moderate to strong oceanic currents.

Taxonomy and Morphology: It belongs to the family Labridae. It features an elongated, laterally compressed body typical of the genus Cirrhilabrus (fairy wrasses). In adulthood, it reaches a maximum length of about 7-8 centimeters, making it an ideal candidate for medium-sized community aquariums. It possesses large, expressive eyes and a rounded caudal fin.

Social Behavior: It is an active, diurnal swimmer that constantly patrols the water column. In the wild, it lives in small haremic groups led by a single dominant male that actively defends its territory and courts the females. It is peaceful towards unrelated tankmates, but males will react aggressively to other male fairy wrasses.

Coloration and Sexual Dimorphism: The coloration is spectacular and displays strong sexual dimorphism. Males feature a distinct tricolor pattern: the upper body is bright red, the lower half is silvery-white, and a yellow band runs horizontally along the middle. The fins are decorated in black and red. Females are simpler, showing a uniform reddish-pink body.

Aquarium Setup: Requires a mature marine aquarium of at least 200 liters with plenty of open swimming space. The tank should be decorated with plenty of live rock arranged to create overhangs and caves for shelter. A secure, tight-fitting mesh screen or lid is mandatory, as this species is an exceptional and powerful jumper.

Diet and Feeding: Diet and Feeding: Primarily carnivorous and planktivorous. In the aquarium, feed a high-quality variety of frozen foods such as mysis, brine shrimp, copepods, and lobster eggs. It also readily accepts enriched dry flakes or pellets. Feed small amounts 2-3 times daily to support its active swimming and high metabolism.

Water Quality: Water Quality: Maintain pristine and stable marine water parameters: temperature between 24°C and 27°C, pH at 8.1-8.4, and specific gravity constant at 1.022-1.025. An efficient protein skimmer and filtration system are essential to keep nutrient levels low, along with moderate to strong water movement.

Compatibility and Cohabitation: Compatibility and Cohabitation: It is 100% reef-safe and does not harm corals, clams, or small ornamental invertebrates. It can coexist with most peaceful reef fish. Avoid keeping it with highly aggressive or territorial species. If keeping multiple specimens, introduce one male with several females simultaneously.

Aquarium Breeding: Aquarium Breeding: Spawning in home aquariums is undocumented. They are pelagic spawners that release eggs and sperm into the water column during twilight vertical spawning runs. Rearing the delicate planktonic larvae requires specialized, sterile rearing facilities and microscopic live foods.

Risks and Diseases: Risks and Diseases: The primary risk is the fish jumping out of the tank when startled, which requires a tight lid. Additionally, it may be shy and remain hidden in the rockwork during the first few days of acclimation; ensure it is not harassed by other tank inhabitants and starts feeding on introduced foods.
