FAQs Answers to the most common questions.
How can I keep a male Laboute’s Fairy Wrasse displaying his brightest colors without causing him stress or aggression issues in my reef tank?
Provide a peaceful, active environment with plenty of open swimming space and high rockwork for display circuits. Use moderate to strong, but diffuse lighting—blue-heavy reef lighting tends to pull out their blues and violets. Keep them with other peaceful or moderately assertive planktivores (like other Cirrhilabrus or Paracheilinus wrasses, anthias, or chromis) so he has “an audience” and some mild social stimulation without being bullied. Avoid very aggressive tankmates (large damsels, dottybacks, big wrasses like Thalassoma) that will suppress his behavior. A small harem (one male with 2–4 females, added before or at the same time as the male) often triggers the most frequent flashing and courtship, but you must ensure ample space (minimum 4 ft tank length; 75–90 gallons or more preferred) and lots of hiding spots so females can retreat. Stable, high-quality water (temp 24–26 °C, salinity 1.025–1.026, very low nutrients but not sterile) and a varied diet rich in carotenoids (mysis, enriched brine, quality pellets, and frozen blends with krill/plankton) will help maximize saturation of their colors without resorting to risky “color-boosting” additives.
My new Laboute’s Fairy Wrasse is pacing the glass and repeatedly “testing” the surface; what specific lid design and escape-prevention measures work best for this species?
Laboute’s Fairy Wrasse is a notorious jumper—fright, sudden shadows, or evening “bedtime” dashes can send it straight out of the tank. Use a tight-fitting top that covers every gap larger than about 6 mm, including cutouts around cords, overflows, and auto-feeders. Clear mesh screen tops in the 1/4" (6 mm) range are ideal because they prevent escape while allowing good gas exchange and light penetration. Avoid egg crate light diffusers; the openings are usually wide enough for a slender wrasse to squeeze through. Check that your lid sits flush and cannot shift if bumped. If you run a rimless tank, custom-cut polycarbonate or mesh frame lids are strongly recommended. Also, dimming lights gradually at “sunset,” avoiding sudden room light changes, and not making abrupt movements at the tank in the evening can reduce panicked launches, but a proper lid is still mandatory for this fish.
Are Laboute’s Fairy Wrasses safe with high-end LPS and SPS corals, and do they have any special behaviors that might still bother delicate reef setups?
Laboute’s Fairy Wrasses are generally coral-safe: they do not nip at coral tissue or polyps and are considered excellent candidates for mixed-reef and SPS-dominant systems. They are mid-water planktivores, spending most of their time cruising and only occasionally picking at the rockwork for small crustaceans. The main consideration is their activity level—they are fast, constant swimmers. In very shallow or low-flow frag racks, their motion can dislodge poorly secured frags or topple light plugs. Mount corals securely with adequate epoxy or glue and ensure small frags are well seated in racks. Also, they can reduce populations of tiny beneficial microfauna (like small copepods in the water column), though usually not enough to harm the ecosystem in a balanced tank. They are safe around clams and ornamental shrimp of moderate size, but newly molted very small shrimp can be vulnerable, so add shrimp first and allow them to settle before introducing the wrasse.
What is the best strategy for introducing a Laboute’s Fairy Wrasse to a tank that already has other fairy and flasher wrasses to minimize hybrid aggression or chasing?
Fairy wrasses often show tension when similar-shaped or similarly colored species are present, especially if adult males are involved. To reduce conflict, rearrange some rockwork just before introduction to “reset” territories. Use an acclimation box (clear perforated container in the tank) for 3–7 days so existing wrasses can see, posture at, and get used to the newcomer without physical contact. Introducing the Laboute’s as a slightly smaller subadult or female is usually smoother than dropping in a full, dominant male. Adding multiple fairy/flasher wrasses at once can diffuse aggression, as no single fish stands out as “the intruder.” Avoid mixing with species known for high fairy-wrasse aggression (some large male C. scottorum, C. rubrimarginatus, or C. cyanopleura can be problematic in smaller tanks). Ensure enough horizontal swimming length (4 ft minimum; 5–6 ft is better) and plenty of caves and overhangs so any chased fish can break line-of-sight. Feed small, frequent meals for the first week after introduction to keep everyone busy and less focused on combat.
I’ve heard deepwater fairy wrasses can be fragile after shipping. What specific acclimation and quarantine routine works best for a Laboute’s Fairy Wrasse?
Laboute’s Fairy Wrasse can arrive stressed due to collection depth and transport. Float the bag to match temperature for 15–20 minutes, then use a drip acclimation process over 30–45 minutes, but do not exceed about an hour total in the shipping water to avoid ammonia toxicity (especially if the bag pH rises once opened). Ideally, match salinity in the quarantine tank to the shipping water or only slightly higher, then slowly bring it up over the next few days. Quarantine in a calm, covered tank with dimmed lighting and plenty of PVC or rock hiding spots. A 20–30 gallon QT is fine for a single specimen. They often respond poorly to harsh medications; copper should be used carefully, within appropriate levels, and with good aeration. Many keepers favor a more gentle approach: observation with prophylactic treatments like a short-course praziquantel for flukes and a formalin or freshwater dip only if there are signs of external parasites. Offer small amounts of varied frozen foods (mysis, small krill, cyclops, finely chopped seafood) several times per day; do not panic if eating is hesitant the first 24–48 hours. Stable temperature, high oxygenation, and low light during the first week are key for this species to settle and recover from transport.

The Labout's Fairy Wrasse, Cirrhilabrus laboutei, is a spectacular saltwater fish known for its intricate striping and vivid combination of red, magenta, yellow, blue, and silvery-white coloration. Also commonly called Laboute's Fairy Wrasse or the Magenta-Streaked Wrasse, this species displays noticeable differences between males and females, with mature males generally developing the most intense coloration. It reaches approximately 4.7–5 inches in total length.
Native to the southwestern Pacific, Cirrhilabrus laboutei occurs around the Great Barrier Reef and Coral Sea as well as New Caledonia, the Loyalty Islands, and Vanuatu. In the wild, it inhabits reef slopes with coral, rock, and rubble at depths of approximately 7–55 meters.
Active yet generally peaceful, this fairy wrasse is an excellent choice for a well-established reef aquarium or peaceful fish-only aquarium. Its brilliant coloration, constant midwater activity, and strong reef compatibility make it particularly desirable for display systems, while its relatively modest adult size allows it to fit comfortably into appropriately sized medium-to-large marine aquariums.

A 70-gallon or larger aquarium provides appropriate long-term swimming room for this active fairy wrasse, which approaches 5 inches as an adult.
Tank Requirements
The Labout's Fairy Wrasse should be provided with a well-established saltwater aquarium containing ample open swimming space combined with secure live rock and caves. Although it spends much of its time actively swimming through the water column, rockwork provides important shelter when the fish is startled or ready to rest. Its natural habitat consists of coral, rock, and rubble along reef slopes.
Unlike wrasses that routinely bury themselves in sand, fairy wrasses of this type retreat into protected areas of the rockwork at night rather than depending on a deep sand bed for sleeping. A specialized substrate is therefore not required, although sand is perfectly suitable as part of a typical reef aquarium setup.
A tight-fitting lid or securely fitted mesh cover is essential. Labout's Fairy Wrasses are strong jumpers and can escape through surprisingly small openings, particularly when newly introduced, startled, or pursued by another fish.
Provide good filtration, stable water quality, and moderate water movement while leaving plenty of unobstructed horizontal swimming room.
Diet and Feeding
The Labout's Fairy Wrasse is primarily a planktivore, naturally feeding on small zooplankton and other tiny marine organisms suspended in the water column. In captivity, it should receive a varied diet of appropriately sized, protein-rich marine foods.
Offer mysis shrimp, enriched brine shrimp, finely chopped krill, copepods, frozen plankton blends, finely chopped marine seafood, and quality marine pellets. Most established specimens adapt well to prepared frozen and dry foods.
Because fairy wrasses naturally feed repeatedly throughout the day, two to three smaller feedings daily are preferable when practical. Regular feeding helps maintain body condition, activity, and coloration.
Temperament and Tankmates
The Labout's Fairy Wrasse is generally peaceful and mixes well with a wide variety of reef-safe community fish. Suitable tankmates include peaceful tangs, anthias, gobies, blennies, cardinalfish, smaller angelfish, and other non-predatory marine species.
Some territorial behavior can occur toward other fairy wrasses, particularly between mature males or similarly colored species. When maintaining several Cirrhilabrus wrasses, a larger aquarium with abundant swimming room and visual breaks is recommended.
A single specimen is an excellent choice for most aquariums. A male may also be maintained with compatible females in a sufficiently spacious system, but multiple mature males of the same species should be approached cautiously. LiveAquaria specifically notes that a male can be maintained with a group of females when introduced appropriately.
Avoid housing this wrasse with large predatory fish or highly aggressive tankmates that may intimidate it or prevent it from feeding normally.
Reef Compatibility
The Labout's Fairy Wrasse is considered reef safe and is an excellent candidate for coral-dominated aquariums. It does not normally damage stony corals, soft corals, zoanthids, or clams and is widely maintained in reef systems.
Unlike many larger wrasses, Cirrhilabrus laboutei is not normally a threat to established ornamental shrimp, crabs, or snails. It will, however, consume tiny planktonic organisms and microcrustaceans as part of its normal feeding behavior.
Its combination of vivid coloration, active swimming behavior, and strong coral compatibility makes it particularly well suited to established mixed and SPS-dominated reef aquariums.
Water Parameters

Common Considerations
-
Exceptional jumping ability: A tight-fitting lid or secure mesh cover is essential for long-term housing.
-
Active swimmer: Despite an adult size of only about 5 inches, this species benefits from substantial horizontal swimming space and a 70-gallon or larger aquarium.
-
Frequent feeding: Small meaty marine foods offered two to three times daily closely suit its natural planktivorous feeding strategy.
-
Wrasse compatibility: Usually peaceful with unrelated fish, but mature males may become territorial toward similar fairy wrasses.
-
Rockwork for security: Provide caves and protected crevices where the fish can retreat at night or whenever it feels threatened.
