Species description

Care, breeding and tankmates

Fish profile

Temperament

Semi-aggressive

It is considered one of the more peaceful and docile Malawi cichlids, though males will still exhibit territorial behavior, particularly when breeding. They show intraspecific aggression towards other males of the same species or fish with similar color patterns. Providing rocky hiding spots helps establish natural territorial boundaries and minimize conflicts.

Diet

Omnivore

In the wild, it is a benthic micro-predator that sifts through the sand in search of small invertebrates and crustaceans. In the aquarium, they should be fed high-quality cichlid pellets or flakes, supplemented with live or frozen foods such as brine shrimp, mosquito larvae, and mysis. Avoid foods that are too rich in terrestrial fats or large items they cannot easily break down.

Life expectancy

5-12 years

Aulonocara stuartgranti has an expected lifespan of 5 to 12 years in captivity when kept under optimal conditions. With regular water maintenance, a balanced diet, and low stress levels, some individuals can reach their maximum longevity. Maintaining stable water parameters is crucial for maximizing their longevity.

Sex ratio

Harem

It is recommended to keep Aulonocara stuartgranti in a harem ratio, consisting of a single male and three to five females. This setup helps distribute the male's aggression during breeding periods, preventing any single female from being excessively chased or stressed. Avoid keeping multiple males in the same tank unless the aquarium is very large and offers plenty of visual barriers.

Feeding frequency

Twice daily

It is advisable to feed Aulonocara stuartgranti once or twice a day, providing controlled portions that can be fully consumed within a few minutes. Some aquarists prefer to offer multiple smaller meals throughout the day to mimic their natural foraging behavior. A weekly fasting day can help maintain a healthy digestive system and prevent obesity issues.

Bioload

Medium

Peacock cichlids like Aulonocara stuartgranti generate a medium bioload due to their protein-rich diet and active metabolism. An efficient filtration system, with a turnover rate of at least 4 to 5 times the tank volume per hour, is essential alongside regular water changes to control nitrates. Waste accumulation can cause stress and health issues in this sensitive species.

Flow

Stagnant

This species prefers a weak to moderate water movement, simulating the transition zones of Lake Malawi without forcing them to constantly swim against violent currents. A well-distributed flow is useful for keeping the water highly oxygenated and conveying waste toward the filter. It is advisable to avoid direct water jets and instead use diffused flow patterns.

Jump risk

Yes

Although Aulonocara stuartgranti is not known as a compulsive jumper, it is an active fish that can easily leap out of the tank when startled or during territorial chases. For this reason, a tight-fitting and secure lid is highly recommended for the aquarium. Any gaps around hoses and cables should also be covered to prevent accidental escapes.

Reproduction

Oviparous

They are maternal mouthbrooders and are relatively easy to breed in the aquarium if water conditions are kept optimal. The male courts the female to a spawning site where she lays eggs, then immediately collects them in her mouth to incubate for about 21 days. During this period, the female does not feed and requires a quiet environment to successfully complete incubation.

Compatibility & tankmates

It is compatible with other peaceful cichlids from Lake Malawi, such as other non-aggressive Peacock species and fish from the genera Copadichromis or Lethrinops. It should not be housed with highly aggressive Mbuna cichlids, which can intimidate or stress them excessively. Additionally, to avoid hybridization, different Aulonocara species should not be kept in the same tank.

Tank level

Middle/Bottom

This species prefers to inhabit the lower and middle zones of the aquarium. They spend significant time swimming close to the sandy substrate, sifting through it for food, but will also move into the midwater region to interact and patrol their territory. It is important to provide a fine sandy substrate and open swimming spaces in these areas.
