Blueside Fairy Wrasse Care Guide
Cirrhilabrus cyanopleura · Saltwater Wrasse

What Blueside Fairy Wrasse look like
The Blueside Fairy Wrasse (Cirrhilabrus cyanopleura) exhibits a strikingly vibrant coloration, characterized by a predominantly blue body with a pronounced iridescent sheen, particularly along the dorsal and lateral surfaces. Adult males can reach a maximum size of approximately 3 inches (7.5 cm), while females are typically smaller and exhibit a more subdued coloration. Sexual dimorphism is evident, with males showcasing more vivid hues and elongated dorsal fins compared to the shorter, rounder fins of females. Defensive adaptations include a streamlined body shape that allows for quick bursts of speed, and the ability to quickly retreat into crevices among the reef structure. Unique morphological features include a well-developed lateral line system that aids in detecting movement in the water column, as well as specialized dentition for grazing on small invertebrates and algae.
Behavior & temperament
Blueside Fairy Wrasses are generally social fish, often found in small groups or pairs within their natural habitat. They inhabit the upper levels of the reef, frequently darting among coral formations. Their breeding behavior is characterized by elaborate courtship displays, where males will perform a series of vibrant color changes and fin displays to attract females. These fish are known for their relatively peaceful temperament, although males can exhibit territorial aggression during breeding seasons, particularly towards other males. They are also known to engage in cooperative behaviors, such as cleaning symbiosis with other reef inhabitants.
Diet & feeding
In the wild, Blueside Fairy Wrasses primarily feed on small zooplankton and benthic invertebrates. In captivity, they require a varied diet that includes high-quality frozen or live foods, such as brine shrimp, mysis shrimp, and finely chopped marine foods.
Behind the name
The genus name 'Cirrhilabrus' derives from the Latin 'cirrus' meaning 'curl' and 'labrus' meaning 'wrasse', referring to the curled form of the dorsal fin in some species. The species name 'cyanopleura' is derived from the Greek 'kyanos' meaning 'blue' and 'pleura' meaning 'side', referencing the distinctive blue coloration on the sides of the fish.
