Distribution and habitat

The distribution area of Cirrhilabrus rubripinnis is the Western Pacific from the Philippines to Sulawesi (Indonesia). There they live mostly in small groups on coral reefs in shallow water rich in currents.

Maintenance

They need a well-structured aquarium with plenty of swimming space and a reef structure that offers hiding, resting and retreat possibilities. It is recommended to use living stones for the aquarium setup. The bacteria living in the porous stones act like a biological filter

Only substrates rich in lime and free of heavy metals should be used as substrate. To ensure water quality, filters, skimmers and heaters are necessary, as well as pumps to simulate tides, swells and bottom currents.  Lighting must correspond to 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 change usually succeeds 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. Only one male should be kept with one or more females. Several animals can be socialized well, if they are put into the aquarium at the same time. Towards other fish they behave peacefully.

Sex dimorphism

They are protogynous hermaphrodites, meaning most males develop from functional females. The males have larger, bright red dorsal and anal fins.

Reproduction and breeding

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

Important

They do not burrow like other wrasses and their coloration may vary according to origin and mood. Since they occasionally jump, make sure the aquarium is well covered

They do 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
