African Lined Wrasse

Geographical Origin and Habitat: Cirrhilabrus africanus is native to the Western Indian Ocean, primarily located along the East African coast, between Mozambique and South Africa, and extending to Madagascar. It inhabits seaward coral reefs and transition zones rich in rocky rubble and coral fragments, typically at depths ranging between 20 and 40 meters.

Taxonomy and Morphology: It belongs to the family Labridae. It features an elongated and slightly laterally compressed body, with large eyes that move independently to spot suspended plankton. Adult males develop long filaments on their pelvic fins and a rounded caudal fin. It reaches a maximum length of approximately 8 centimeters in adulthood.

Social Behavior: It is an active and diurnal fish that spends the day swimming in the water column looking for food. In the wild, it lives in harems consisting of a single dominant male and several females with a defined hierarchy. Males display spectacular flashing behaviors to maintain their harem and deter rivals, but are peaceful to other species.

Coloration and Sexual Dimorphism: Sexual dimorphism is extremely pronounced. Males display a spectacular coloration with shades of red, orange, yellow, and electric blue, along with finely decorated fins. Females are smaller, with a predominantly uniform reddish or pinkish coloration and fewer details. Juveniles look like females.

Aquarium Setup: Requires a reef aquarium of at least 200 liters with plenty of open swimming space. It is essential to provide a setup with live rock arranged to form spacious caves and crevices for the fish to retreat to at night or when startled. A tight-fitting lid is mandatory, as this fish is an exceptional jumper.

Diet and Feeding: Carnivorous and planktivorous. In the aquarium, it must be fed a rich and varied diet of frozen foods such as mysis, brine shrimp, copepods, chopped krill, and fish eggs. It also readily accepts high-quality dry pellets or flakes. It is recommended to feed small amounts several times a day to match their high metabolism.

Water Quality: Requires optimal water quality and stable parameters: temperature 24-28°C, pH 8.1-8.4, and specific gravity 1.022-1.025. It is important to keep nitrogenous compounds low through efficient filtration and regular water changes. Good water movement and excellent oxygenation are essential for its well-being.

Compatibility and Cohabitation: It is a peaceful and completely reef-safe species that does no harm to corals or sessile invertebrates. It can coexist with most peaceful reef fish. Avoid keeping it with aggressive or dominant species like large tangs or other territorial wrasses. If keeping a harem, introduce the females first before the male.

Aquarium Breeding: Reproduction in the aquarium is not commonly documented. They are pelagic spawners that release eggs directly into the open water column during vertical swimming rituals towards the surface. The planktonic larval stage is extremely delicate and requires specialized facilities and live microscopic foods to survive.

Risks and Diseases: The primary risk is associated with the fish jumping out of the tank when startled, especially during introduction or at night, making a lid crucial. Additionally, it can be shy during the initial days; ensure it feeds regularly and is not bullied by tankmates. It may contract external parasites if severely stressed.
