Blueside Fairy Wrasse - Female

The female Blueside Fairy Wrasse, Cirrhilabrus cyanopleura, is an elegant saltwater fish displaying warm brown, reddish-orange, and pink tones that transition into a noticeably paler underside. Fine pale blue markings may appear across the body, giving females a softer appearance than the intensely colored mature males. Like other fairy wrasses, females can transition into males depending on social conditions, with coloration becoming substantially more dramatic during that change.

Native to the Indo-West Pacific, this species inhabits lagoon edges, reef slopes, and mixed coral-and-rubble environments, where groups swim above the reef feeding on zooplankton. Its graceful open-water swimming, manageable adult size, peaceful temperament, and excellent coral compatibility make it a desirable marine aquarium fish for established reef aquariums and peaceful fish-only systems.

Tank Requirements

The Blueside Fairy Wrasse should be maintained in an established saltwater aquarium with ample open swimming space and abundant rockwork for shelter. A 75-gallon or larger aquarium provides appropriate long-term room for this active fairy wrasse.

Arrange live rock to create caves, overhangs, and narrow crevices where the fish can retreat when startled and rest at night. Unlike sand-burying wrasses, Cirrhilabrus species normally shelter within reef structure and do not require a deep sand bed.

Moderate water movement, good oxygenation, efficient filtration, and stable water quality are ideal.

A tightly fitted mesh or solid aquarium cover is essential. Fairy wrasses are exceptionally capable jumpers and can escape through surprisingly small openings around plumbing, equipment, and aquarium edges.

Diet and Feeding

The Blueside Fairy Wrasse is primarily a planktivore, naturally feeding on zooplankton and small crustaceans suspended in the water column.

Offer a varied diet including mysis shrimp, enriched brine shrimp, copepods, finely chopped marine seafood, frozen plankton blends, and appropriately sized high-quality marine pellets. Foods that remain suspended in the water encourage natural feeding behavior.

Two to three smaller meals per day are preferable when practical. Established aquariums containing natural copepod populations can provide additional feeding opportunities between prepared meals.

Temperament and Tankmates

The Blueside Fairy Wrasse is generally peaceful and compatible with a wide range of non-aggressive marine aquarium fish. Suitable tankmates include clownfish, gobies, blennies, cardinalfish, anthias, peaceful tangs, and other community-oriented species.

Some territorial or display behavior may occur with other fairy wrasses, particularly individuals with similar coloration or body shape. Multiple fairy wrasses can be maintained in sufficiently spacious aquariums when species selection and introductions are carefully planned.

Like other Cirrhilabrus species, the Blueside Fairy Wrasse is a protogynous hermaphrodite. A female can transition into a male when social conditions favor the change.

Avoid highly aggressive tankmates that may continually intimidate the wrasse or prevent it from feeding comfortably.

Reef Compatibility

The Blueside Fairy Wrasse is considered reef safe. It does not normally damage healthy corals and is generally compatible with ornamental shrimp, crabs, snails, clams, and other common reef invertebrates.

Its feeding behavior is focused primarily on small planktonic organisms in the water column rather than larger benthic invertebrates. Naturally occurring copepods and other tiny crustaceans may be consumed as part of its normal diet.

This combination of peaceful behavior and excellent coral compatibility makes it particularly well suited to mixed and coral-dominated reef aquariums.

Water Parameters

Temperature: 75–80°F
Specific Gravity: 1.024–1.026
pH: 8.1–8.4
Alkalinity: 8–12 dKH

Stable conditions are more important than repeatedly adjusting the aquarium to reach an exact value. Maintain consistent temperature and salinity along with good oxygenation, dependable filtration, and regular aquarium maintenance.

Common Considerations

• Female coloration: Females are generally softer brown, reddish, or pinkish tones with pale blue markings and a lighter underside than mature males.

• Sex change possible: Females may transition into males depending on the social structure of the aquarium.

• Exceptional jumping risk: A tightly fitted aquarium cover is essential, including protection around plumbing and equipment openings.

• No sand bed required: This fairy wrasse normally sleeps and shelters within rockwork rather than burying itself in sand.

• Frequent feeding: Multiple small meals of appropriately sized planktonic and protein-rich foods help maintain healthy body condition.
