Blue Throat Fairy Wrasse (Cirrhilabrus Cyanogularis) saltwater aquarium fish portrait

Cirrhilabrus cyanogularis is a slender, fast-moving fairy wrasse from the Indo-West Pacific, with verified records from the Philippines and Indonesia and photographic documentation from Malaysia. Mature males carry a red-orange to yellow-orange body set against a vivid blue throat, lower head, and breast, while females remain paler and more subdued. Diagnostic features include that extensive blue underside, long pelvic fins reaching past the origin of the anal fin, the absence of a middle dorsal filament, six predorsal scales, and a narrow black stripe running through the soft dorsal fin. In the wild it associates with outer-reef rubble slopes, and adults in aquaria may reach approximately 6 inches.

Adult housing should begin at a 75-gallon aquarium, and larger footprints are frequently recommended for harem groups or busy reef systems. The layout matters as much as the volume: combine long stretches of open water for cruising with substantial rockwork arranged into caves, crevices, and overhangs where the fish can retreat and sleep. Moderate to strong flow, efficient filtration, and stable water chemistry suit this active planktivore, and a moderate sand bed mirrors the rubble habitat it occupies naturally. A tightly fitted lid or full canopy is not optional, as this wrasse is a documented jumper and will find any open gap around plumbing or overflow returns.

On the reef, this species works the water column as a zooplankton feeder, picking copepods and other small invertebrates from the current. That grazing pattern translates directly into captive feeding: offer small meaty items rather than large single portions. Vitamin-enriched mysis shrimp, enriched brine shrimp, live or frozen copepods, finely chopped marine seafood, and mixed frozen preparations all suit its mouth size and appetite.

Supplement the frozen rotation with small marine pellets or flakes formulated for carnivores so the diet stays varied. Because the fish swims almost continuously and burns energy accordingly, feed small portions two to three times daily, or several times per day where a feeder or refugium population can help. Reviewed information on this species does not indicate any particular difficulty in getting new arrivals to accept prepared foods, though a calm aquarium without pushy competitors makes the transition smoother.

Expect a peaceful, restless swimmer that patrols open water for most of the day and darts into rockwork when startled. It mixes well with other calm community fish and should not be housed with aggressive or strongly territorial tankmates that would intimidate it or monopolize food at feeding time. Mature males are the one exception to the easygoing nature: they may flare and display toward other males or toward similar fairy wrasses competing for the same space, so allow generous swimming room before attempting such combinations.

A single specimen settles well, and a harem of one male with several females is the more rewarding arrangement in a spacious system. Introducing the females first, or simultaneously with the male, reduces friction as the group establishes itself. Within the reef, this wrasse is considered safe with corals and does not bother the common ornamental invertebrates most reef keepers maintain, but very small shrimp and tiny crustaceans may be treated as prey by a fish that hunts zooplankton for a living.

FAQ

Frequently Asked Questions

About the Blue Throat Fairy Wrasse

  • What aquarium size and layout should I prepare?
    Plan on a 75-gallon aquarium or larger for adults, arranged with open swimming lanes and abundant rockwork for shelter. Fit a secure lid, since this wrasse is prone to jumping.
  • Can it live in a reef aquarium with ornamental invertebrates?
    Yes, it is reef safe and normally leaves corals and common invertebrates untouched. Very small shrimp and tiny crustaceans, however, may be eaten by this zooplankton feeder.
  • Can I keep more than one Blue Throat Fairy Wrasse?
    One male with several females works well in a sufficiently spacious aquarium, ideally with the females introduced first or at the same time. Avoid pairing competing mature males, as they may display aggression toward one another.
