Freiberg's Peacock Care Guide - Aquarium Setup, Diet & Breeding

Freiberg's Peacock is a colourful Lake Malawi cichlid belonging to the Aulonocara group, widely known as peacock cichlids. Mature males develop vivid blue colouring over the head and body, often combined with yellow, orange or red markings that vary between regional forms. Females are much more subdued, generally silvery brown or grey with darker vertical bars.

This species is active and observant rather than relentlessly aggressive. Males may defend a small spawning site and display dramatically to females or rival males, but they typically do not show the same intense rock-territory aggression associated with many mbuna cichlids. Individual temperament varies with aquarium size, layout and the number of available territories.

In the lake, Freiberg's Peacock lives over sandy areas close to rocky habitat. Its unusual sensory pores help it detect tiny invertebrates concealed in the substrate, and it sifts mouthfuls of sand to locate prey. This feeding method gives the fish a distinctive, deliberate behaviour as it searches across the lake bed.

The name Aulonocara jacobfreibergi covers several attractive geographic colour varieties, and these forms should be kept separate if maintaining reliable lines. Mixing related peacock cichlids can result in territorial conflict and unwanted hybridisation, particularly when different males are housed with females of similar appearance.

Freiberg's Peacock is native to Lake Malawi in East Africa, where it occurs around rocky shorelines and islands in the lake's clear, alkaline waters. The species is associated with several local geographic forms, including populations around Cape Maclear, Otter Point and Undu Reef.

A single male with females should be given at least a 250-litre aquarium, with a footprint of roughly 120 cm by 45 cm; a larger tank is preferable for a mixed Malawi community or multiple territories. Use a fine, smooth sand substrate so the fish can sift naturally without damaging its mouth. Arrange limestone or other aquarium-safe rocks into caves, crevices and broken sightlines, while leaving open sandy areas for foraging and spawning. Strong filtration, good oxygenation and stable, alkaline water are important, and any decor must be secure because these cichlids may excavate around it.

Males reach about 15 cm (6 inches) in length, while females are usually smaller at approximately 10–12 cm (4–4.7 inches).

Freiberg's Peacock Cichlids are omnivorous predators that naturally pick small crustaceans, insect larvae and other invertebrates from sand and rock surfaces. Offer a varied diet based on a quality cichlid pellet or granule, supplemented with spirulina-rich foods and occasional frozen or live foods such as brine shrimp, mysis shrimp and daphnia. Avoid making fatty mammalian foods or large amounts of meaty food a regular part of the diet, and feed modest portions several times a day rather than one excessive meal.

Suitable companions include other relatively peaceful Lake Malawi haplochromine cichlids, such as compatible Aulonocara varieties and carefully selected Copadichromis or Placidochromis species of similar size and temperament. Avoid keeping more than one male of the same colour form in a modest aquarium, and do not combine them with similarly shaped peacock females if preventing hybridisation is important. Highly aggressive mbuna, fin-nipping species, very small fish and calm community fish from other regions are poor choices.

Freiberg's Peacock Cichlids are maternal mouthbrooders. Spawning usually takes place over a cleared area or a shallow sand pit, where the male displays and fertilises the eggs as the female collects them in her mouth. She incubates the eggs and fry for around three weeks, often refusing food during this period. In a breeding-focused aquarium, provide one male with several females and move the female to a quiet separate tank if the fry are to be raised safely. Newly free-swimming fry can be fed finely powdered fry food and newly hatched brine shrimp.

Males are considerably larger and develop intense blue, yellow, orange or red coloration, depending on their geographic form. Females remain smaller and mainly silver-grey or brown with subdued vertical bars, while juveniles and immature males can resemble females.
