Naoko's Fairy Wrasse Care Guide: Tank Size, Diet & Reef Behavior

Learn Naoko's Fairy Wrasse (Cirrhilabrus naokoae) care: 50+ gallon tanks, mysis diet, male shark-fin displays, harem stocking, jump-risk lids, and what to check before you buy on ReefBay.

The Naoko's Fairy Wrasse (Cirrhilabrus naokoae) is a slender, high-energy fairy wrasse from northern Sumatra that rewards reef keepers with mid-water color and male display. Terminal males show a red body with yellow and white striping, a silvery-white belly, black-margined pectorals, and a tall shark-fin dorsal they flash brighter during courtship; females stay plainer red with fine bluish-white lines. Adults top out around 4 inches, stay reef-safe with corals, and need a tight lid — this species is a proven jumper.

This guide covers tank size, diet, harem stocking, jump risk, and a practical ReefBay buying checklist. When you are ready to purchase, compare live listings in the ReefBay marketplace against the care targets below.

Quick care snapshot

• Scientific name: Cirrhilabrus naokoae
• Also called: Naoko Fairy Wrasse, Naoko's Wrasse, Shark Fin Fairy Wrasse, Naoko's Fairy Flasher Wrasse
• Category: Wrasse
• Origin: Indian Ocean — northern Sumatra, Indonesia
• Care level: easy
• Temperament: peaceful with unrelated tankmates; territorial toward other Cirrhilabrus and Paracheilinus wrasses
• Reef-safe: yes with corals; inverts with caution
• Suggested tank: mature 50+ gallons with open swim space and rock refuge
• Max size: about 4.0 inches
• Social: small group — ideally one male with a small female harem, or a single male
• Diet: carnivore — mysis, enriched brine, zooplankton, quality pellets/flake
• Jump risk: yes — use a tight-fitting lid
• Dimorphic: yes — males show the tall dorsal and brighter display color

Tank size, aquascape, and flow

Plan for a mature system of about 50 gallons or larger. Naoko's Fairy Wrasses are open-water cruisers, not sand-sifters. They want mid-water lanes to patrol, live rock caves to duck into when startled, and stable reef parameters before you add them.

• Leave clear swim space above and in front of the rockwork for male flashing displays
• Provide caves and overhangs so a new fish can settle after lights-on
• Keep flow moderate to strong enough for planktonic foods to drift without blasting their hangouts
• Add them only after the tank is cycled and parameters are boringly stable

In a tighter footprint, a single male is safer than forcing a full harem. In larger mixed reefs, one male with a small group of females is the classic setup when you introduce them together (or add the male early) and watch early dominance toward other fairy/flasher wrasses.

Diet and feeding schedule

Treat this species as a true carnivore planktivore: mysis, enriched brine, zooplankton, and quality pellets or flake. Offer several small meaty feedings per day rather than one heavy meal so the male and females all get a share.

1. Feed small meaty foods 2–3+ times daily
2. Target mid-water so shy females are not outcompeted by faster anthias, chromis, or other wrasses
3. Keep copepods and finely chopped frozen foods in rotation for condition and color
4. Ask sellers for recent feeding video — fish already hitting mysis or pellets settle faster

Thin bodies and faded red usually mean food competition or too few feedings, not “mystery disease” first. Captive-acclimated fish that already eat prepared foods on ReefBay listings are worth prioritizing.

Compatibility, harems, and reef behavior

Naoko's is generally peaceful with unrelated tankmates but territorial toward other Cirrhilabrus and Paracheilinus wrasses. Sexes are dimorphic, so plan stocking around a single male or a male-with-harem rather than a crowd of adult males.

• Best social setup: one male, or one male with a small female harem, in 50+ gallons; add it early if other fairy/flasher wrasses will share the system
• Often works: clownfish, peaceful gobies and blennies, chromis, cardinalfish, most LPS/soft and mixed reefs
• Watch closely: other adult male fairy/flasher wrasses, aggressive dottybacks, or large predatory wrasses in a tight tank
• Inverts and corals: reef-safe with corals; treat ornamental shrimp with caution and keep the wrasse well fed
• Quarantine: still QT — peaceful does not mean parasite-proof

Jump risk — lid required

Fairy wrasses are notorious jumpers, and Naoko's is explicitly flagged as jump-risk. A tight-fitting lid or mesh cover is not optional, especially during acclimation, after lights-out startle events, and when chasing food near the surface.

• Cover every rim gap, overflow notch, and cable cutout
• Dim lights for the first evenings after introduce
• Avoid sudden shadows and aggressive surface netting

Buying checklist on ReefBay

Before you tap Buy on a Naoko's Fairy Wrasse listing, verify:

• Clear, recent photos or video showing body thickness, alert swimming, and (for males) intact tall dorsal and bright display color
• Seller notes on diet (mysis / pellets) and quarantine history
• Your tank is 50+ gallons with open mid-water space and a tight lid
• You have a stocking plan: solitary male, or one male with multiple females — and a plan for other fairy/flasher wrasses
• Compare active listings and seller reputation in ReefBay before you commit
