Butterfly Peacock Cichlid Varieties

Each variety inherits the species defaults above. Only differences are highlighted.

Male (Show / Color Morphs)

Boasts spectacular, highly variable coloration (vibrant reds, yellows, and blues depending on locality) with pronounced white dorsal edges. Highly territorial toward conspecific males. Best kept as a solitary male in a mixed, all-male peacock tank, or as a single male with a harem of females.

Differs in 3 traits from base species

Also known as: Eureka Red Male, Undu Reef, Otter Point, Standard

Adult Size17 cm
TemperamentAggressive
StockingSolo only

Female

Drab silver, brown, or grey coloration. Significantly more peaceful than males. If keeping a breeding group, strict harems of 3 to 4 females per single male are required to disperse his aggressive mating behavior.

Butterfly Peacock Cichlid Care Guide Summary

The Butterfly Peacock Cichlid, scientifically known as Aulonocara jacobfreibergi, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 15 cm and have a fusiform body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a high level of biological waste.

To thrive, the Butterfly Peacock Cichlid requires a freshwater only aquarium with a minimum volume of 208 litres and a tank length of at least 120 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 7.88.6 and a general hardness of 1025 dGH. A moderate water flow is preferred.

The Butterfly Peacock Cichlid is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Male (Show / Color Morphs) and Female. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

Butterfly Peacock Cichlid Habitat Setup

When setting up an aquarium for the Butterfly Peacock Cichlid, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and smooth gravel or rounded substrate to protect their sensitive barbels. Keepers should note that expect substrate disturbance, so lightweight décor should be secured.

Butterfly Peacock Cichlid Compatibility Notes

Classified as semi-aggressive, the Butterfly Peacock Cichlid is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, conspecific aggression can be intense, especially in smaller tanks, territorial behaviour may cause issues if hiding spots or floor space are limited, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Who Butterfly Peacock Cichlid Is Actually For

Butterfly Peacock Cichlid is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Butterfly Peacock Cichlid like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

Peacock Cichlid (Aulonocara)

Aulonocara sp.

Cichlids - African
15 cm Semi-Aggressive

Endemic to Lake Malawi, Peacock Cichlids are highly sought after for the breathtaking colors of the males. They are benthivorous, using sensory pores on their jaws to hunt small invertebrates in the sand. While territorial, they are generally peaceful compared to their aggressive Mbuna cousins. They require hard, alkaline water and a sandy substrate to prevent gill damage while sifting.

Maison Reef Peacock

Aulonocara stuartgranti "Maison Reef"

Cichlids - African
13 cm Semi-Aggressive

A stunning African Cichlid from Lake Malawi's intermediate zones (sand/rock transitions). They are 'benthophagous' sand-sifters, requiring fine sand to hunt for invertebrates without damaging their gills. Like most Peacocks, they are highly sexually dimorphic and require hard, alkaline water (Rift Lake parameters).

Orange Peacock

Aulonocara stuartgranti maleri

Cichlids - African
14 cm Semi-Aggressive

A stunning Lake Malawi cichlid prized for its vibrant coloration. As an Aulonocara species, they possess sensory pores on their lower jaw to detect prey in the sand. They are relatively peaceful for African cichlids (compared to Mbuna) but require hard, alkaline water, a sandy substrate, and plenty of rockwork. They exhibit extreme sexual dimorphism.

Fort Maguire Peacock

Aulonocara hansbaenschi

Cichlids - African
13 cm Semi-Aggressive

A stunning Lake Malawi Peacock cichlid known for the male's metallic blue body and vibrant red/orange flush behind the gills. Like all Aulonocara, they are benthivores (sand-sifters) that hunt small invertebrates using enlarged sensory pores on their lower jaw. They require hard, alkaline water and a fine sand substrate to exhibit natural behaviors without damaging their gills.

Yellow Peacock Cichlid

Aulonocara baenschi

Cichlids - African
13 cm Semi-Aggressive

A striking Lake Malawi cichlid known for the male's vibrant yellow coloration and metallic blue face. As a 'Peacock' cichlid, they are benthic carnivores that require fine sand to sift for invertebrates. While considered one of the more mild-mannered African cichlids, they still require hard, alkaline water and careful management of aggression, usually via an all-male display tank or a harem structure.

Aulonocara stuartgranti

Cichlids - African
13 cm Semi-Aggressive

A stunning endemic cichlid from Lake Malawi known as a 'Peacock'. They feature specialized sensory pores on their lower jaw to hunt small invertebrates in the sand. Requires hard, alkaline water and a soft sandy substrate to prevent damage to their gills during natural sifting behavior.
