Blue Throat Fairy Wrasse - Cirrhilabrus cyanogularis

Blue Throat Fairy Wrasse (Cirrhilabrus cyanogularis)

The Blue Throat Fairy Wrasse is a striking and elegant marine wrasse admired for its vivid colouration, graceful body shape and distinctive blue throat markings in mature males. Like many Cirrhilabrus species, males can intensify their colours during social or courtship displays, making this an especially attractive addition to established reef aquariums. Peaceful, reef safe and highly active, it is best kept with calm tankmates, plenty of secure rockwork and a tightly fitted aquarium lid.

Common Name:
Blue Throat Fairy Wrasse

Scientific Name (Latin):
Cirrhilabrus cyanogularis

Maximum Size:
Approximately 8–9 cm

Water Type:
Marine

Origin / Natural Habitat:
The Blue Throat Fairy Wrasse is associated with tropical reef environments containing coral-rich slopes, rocky structure and areas of open water.

It typically spends the day swimming above and around the reef while remaining close enough to caves and crevices to retreat quickly when threatened.

Water Parameters:
Temperature: 24–26°C
pH Range: 8.1–8.4
Salinity: SG 1.024–1.026
Nitrate: Low and stable
Ammonia/Nitrite: 0 ppm

Temperament:
Peaceful

The Blue Throat Fairy Wrasse is generally peaceful towards unrelated marine fish and is well suited to established community reef aquariums.

Mature males may display towards other fairy wrasses and can become mildly territorial towards similar Cirrhilabrus species, particularly where aquarium space is limited.

Diet:
Carnivore / Planktivore

The Blue Throat Fairy Wrasse naturally feeds on small planktonic organisms within the water column.

In the aquarium, offer a varied diet including frozen mysis, enriched brine shrimp, copepods, finely chopped krill and quality small marine pellets or flakes.

Several smaller meals throughout the day are beneficial because fairy wrasses are active swimmers with relatively high energy requirements.

Minimum Tank Size:
Approximately 150 litres

A mature aquarium with plenty of open swimming room and established rockwork is recommended.

Behaviour & Activity:
The Blue Throat Fairy Wrasse is an energetic daytime swimmer that commonly occupies the middle and upper areas of the aquarium.

Mature males may intensify their colouration and extend their fins during social or courtship displays.

Provide substantial open swimming space alongside caves, overhangs and secure rockwork where the fish can retreat and sleep.

Fairy wrasses do not require a deep sandbed for sleeping and instead shelter within reef structure.

A tightly fitted aquarium lid is essential, as Cirrhilabrus wrasses are accomplished jumpers.

Reef Safe:
Reef Safe

The Blue Throat Fairy Wrasse is generally considered reef safe and does not normally damage healthy corals, clams or established ornamental invertebrates.

Its feeding behaviour is centred primarily on small planktonic foods rather than coral tissue or larger reef inhabitants.

Special Requirements or Care Notes:
Provide a mature marine aquarium with stable water chemistry, good filtration and plenty of secure rockwork.

A tightly fitted lid covering all openings is essential because fairy wrasses can jump suddenly when startled, during feeding or during acclimation.

Avoid aggressive or highly territorial tankmates that may intimidate this relatively peaceful species.

If keeping several fairy wrasses, provide ample swimming space and introduce them carefully to reduce territorial disputes.

Regular varied feeding helps maintain healthy body condition and strong colouration.

Newly introduced specimens may initially remain close to shelter but usually become more confident once established.

Suitable for:
Intermediate
