Distribution and habitat

The distribution area of Cirrhilabrus cyanogularis is the Western Pacific, where they occur from Sulawesi to the Sulu Sea near the Philippines. They live there over rocks or boulders on reefs down to depths of 30m.

Maintenance

They require a well-structured aquarium with plenty of swimming space and a reef structure (hiding, resting and retreat possibilities) with living stones that act like a biological filter as well as a substrate of sand or fine gravel and a strong current. Only lime-rich, heavy metal-free substrates may be used as substrate.

Filters, skimmers and heaters are necessary to ensure water quality, as well as pumps to simulate tides, swells and bottom currents. Lighting must match the species-appropriate day-night rhythm of the animals

Salinity: 33-36 ‰	pH value: 8.1-8.4
Carbonate hardness: 8-10 °KH	Nitrate content: 2-8 mg/l
phosphate content: 0.01-0.1 mg/l	nitrite content: 0.0-0.05 mg/l

For salinity, an average value should be aimed for, which may only vary slightly by +/- 0.5 ‰. Ammonia and ammonium must not be measurable. Special attention must be paid to constantly good water quality.

Diet

In nature they feed mainly on zooplankton. The feed changeover does not always succeed without problems. The food supply for these slow eaters should consist of a commercially available, vitamin-enriched, frozen special food mix for plankton eaters or a combination of chopped shrimp and crab meat with live and frozen foods, such as mysis, krill, bosmids, cyclops and Artemia. High quality flake and granulated foods are also often accepted after a period of acclimation

It is recommended to feed small portions several times a day (3-5 times). This also reduces intra-species aggression. Regular and varied feeding promotes health and increases resistance.

Behaviour and compatibility

The young fish, mostly females, are peaceful among themselves and can be kept without problems. With the sex change to male the aggression increases. They should be kept in pairs or in a group of at least 5 animals. Several animals can be socialized well, if they are put into the aquarium at the same time. They behave peacefully towards other fish.

Sex dimorphism

They are protogynous hermaphrodites, meaning most males develop from functional females. The males are reddish-yellow in color with a blue fringed caudal fin

Reproduction and breeding

There are no known reports of successful breeding in the aquarium.

Important

Especially during acclimation they jump frequently, so make sure the aquarium is well covered

They can be kept very well in a reef aquarium with corals and invertebrates and should not be kept in a fish-only aquarium.

If different species are kept together, care should be taken to match the fish in terms of water quality and temperature requirements and social behavior, and to ensure that the setup meets the needs of all species kept together. New fish to be introduced must be acclimated slowly to the water in the aquarium
