Distribution and habitat
The distribution area of the Aurora Malawi Cichlids is exclusively (endemic) Lake Malawi, where they are found near Likoma Island (Malawi) and between Mara Point and Tumbi Point on the east coast of the lake (Mozambique) and have produced several site variants. They belong to the Mbuna group, which lives in the rocky shore zones.
Maintenance
The aquarium setup should have rock structures reaching to the water surface, with many crevices, caves and shelters that serve as hiding places, as well as robust plants and some free sand areas. There should be no detectable ammonia, ammonium or nitrite, and the nitrate level should not exceed 100 mg/l. To ensure the water quality and oxygen content, a filter and heater adapted to the aquarium size is required, as well as lighting for the species-appropriate day-night rhythm of the animals.
Diet
They feed mainly on plankton as well as on the plant cover (growth) and the microorganisms contained therein. The food supply consists of live, frozen and dry food. For a balanced diet, feed once daily with a high quality dry food for Malawi cichlids (flakes, granules, pellets) as well as cyclops, daphnia, artemia and plankton (live or frozen). In addition, they also need plant food, such as algae leaves, scalded leafy and wild vegetables or high-quality dry food with plant components (kelp, spirulina)
Only feed as much as will be eaten within a few minutes. A regular and varied diet promotes health and increases resistance.
Behaviour and compatibility
Males occupy territories which they defend vigorously against conspecifics, they are not very aggressive towards other fish. They should be kept in a harem, one male with several females. Keeping several harems is only recommended in a larger and richly structured tank. They can be socialized well with other cichlids from Lake Malawi, especially from the Mbuna group. Basically, only compatible fish species with similar demands on water condition and water temperature should be socialized.
Sex dimorphism
The male is strongly colored and has distinct yellow egg spots on the anal fin, which are weaker or absent in the female. The female is dark brown in color with an indicated transverse stripe pattern.
Reproduction and breeding
They are maternal mouth brooders. The female usually spawns on a flat rock. After the male fertilizes the eggs, she immediately takes the female into her throat pouch for mouth brood care and keeps the fry in her throat pouch even after they hatch. After about 4 weeks, the fry are released and brood care ends. During the entire brood care, the female does not take any food.
Fry must be fed several times a day with special rearing food (Artemia nauplii). In community tanks breeding is hardly possible, because the fry is easy prey.
Important
Different site varieties of Aurora malawi cichlids should not be maintained together, as they may interbreed
The well-being of the fish should be checked regularly. Temperature should be checked daily, pH, hardness and nitrate levels should be checked at least every 14 days. Regular partial water changes are recommended, even when contaminant levels have not yet reached the upper limit. Sudden changes in water quality should be avoided. Newly introduced fish must be accustomed slowly to the water in the aquarium.
