Haplochromis nyererei is one of the most colourful cichlids on Lake Victoria. Much sought-after by aquarists for its fiery red, yellow and violet **reflections in the males**, it is also fascinating for its territorial and dynamic **behaviour**.

Behaviour & maintenance

This cichlid has :

• A territorial temperament, especially in adult males
• A marked social hierarchy - recommended ratio: 1 male to 2-3 females
• Highly active: it likes to swim in open water and defend rocky areas.

We recommend keeping it in a special Victoria aquarium or with other robust, non-aggressive cichlids.

Diet

Omnivorous with carnivorous tendencies:

• High-quality pellets for African cichlids
• Supplements: artemia, krill, daphnia
• Avoid food that is too rich in fat or soft plants

A varied diet improves health and intensifies colour.

Water quality

• Temperature: 24 - 27°C
• pH: 7.5 - 8.2
• GH: 8 - 16 °dGH
• KH : 6 - 12 °KH
• Conductivity: 200 - 400 µS

This cichlid likes hard, alkaline, well-oxygenated water. An external filter is strongly recommended.

Decor & environment

Choose :

• Rocks and boulders to mark out territories
• Neutral sand or fine substrate
• Strong lighting to enhance the metallic reflections of the males

Recommended volume: 200 L minimum for a trio (1 male + 2 females).

Aquabota tip

For explosive colours, opt for a krill- and carotene-based diet, good LED lighting and a low density of males in the tank. A well-established dominant male is a real living jewel in the aquarium!
