Red-scaled Fairy Wrasse

Geographical Origin and Habitat: This tropical marine species is native to the western Indian Ocean, with populations recorded primarily around the Maldives and the Chagos Archipelago. It is a deep-water reef dweller, inhabiting steep outer slopes, rocky walls, and rubble-strewn zones at depths between 40 and 70 meters, where light levels are naturally lower.

Taxonomy and Morphology: Cirrhilabrus rubrisquamis belongs to the Labridae family, genus Cirrhilabrus (fairy wrasses). It features an elongated, moderately compressed body shape with large red eyes and a rounded caudal fin. The scales on the anterior half of the body are prominent and dark-edged. Adult specimens reach a maximum standard length of about 7.5 to 8.0 cm.

Social Behavior: It is an active, peaceful swimmer that spends its day in the middle and upper water column. In the wild, they live in haremic groups composed of a single dominant male and multiple females. Dominant males perform spectacular courtship displays at dusk, flashing iridescent colors and flaring their fins to attract females.

Coloration and Sexual Dimorphism: Sexual dimorphism is highly pronounced. Males exhibit a bright red-orange anterior body (head and front back) with dark-rimmed scales, transitioning to a golden-yellow or white posterior body. The fins are highlighted with electric blue and purple. Females are smaller and display a uniform pinkish-orange coloration.

Aquarium Setup: Requires an established reef aquarium of at least 200 liters (50 gallons). The aquascape should feature a large open swimming area in the center and plenty of live rock arranged to create caves, overhangs, and shady zones that simulate its deep-reef habitat. A tight-fitting lid or screen mesh cover is mandatory, as this wrasse is a powerful jumper.

Diet and Feeding: Carnivorous zooplankton feeder. It has a fast metabolism and should be fed two or three times daily. Offer a varied diet of frozen foods such as mysis shrimp, brine shrimp, copepods, and finely chopped seafood. High-quality marine flakes and micro-pellets are easily accepted once the fish is settled.

Water Quality: Requires stable marine parameters: water temperature between 22°C and 26°C, pH between 8.1 and 8.4, specific gravity of 1.020 to 1.025, and KH between 8 and 12. An efficient protein skimmer and quality filtration are necessary to keep nitrates low. Gentle to moderate water flow is preferred.

Compatibility and Cohabitation: 100% reef-safe and compatible with all corals and sessile invertebrates. Suitable tankmates include other peaceful reef species such as clownfish, anthias, small gobies, and blennies. Do not house multiple males of the same or similar Cirrhilabrus species in the same tank to prevent severe fighting. Avoid large, predatory fish.

Aquarium Breeding: Protogynous hermaphrodite. Spawns in the open water column. At dusk, the male and a receptive female perform a rapid vertical ascent to release their eggs and sperm. The eggs are pelagic. Captive breeding in home aquariums is extremely difficult due to the challenges of feeding and rearing the microscopic larvae.

Risks and Diseases: The primary risk is jumping out of open-topped tanks. It may appear shy during the first few days, hiding in the rockwork. Susceptible to common marine ectoparasites like marine ich (Cryptocaryon irritans) under stressful conditions, but responds well to standard medications. Quarantine new specimens before introduction.
