Eureka Red Peacock Cichlid - Aulonocara jacobfreibergi Eureka : Complete Fish Profile & Care Guide
Table of contents
Introduction
Eureka Red Peacock Cichlids (Aulonocara jacobfreibergi Eureka) occupy a prominent position among aquarists worldwide as one of the most highly favoured freshwater fish. These Cichlids are renowned for their sociable and active nature, displaying compatibility with a diverse range of other freshwater aquarium fish. However, it is essential to acknowledge that aggressive territorial behaviours, such as chasing, nipping, and fighting, may manifest when these Cichlids are exposed to confined tank conditions or imbalanced male-to-female ratios.
When selecting suitable tank companions for Eureka Red Peacock Cichlids, it is advisable to choose fish species that thrive in similar water conditions. Ideally, peaceful and amicable fish occupying the upper regions of the tank proved to be the most compatible tank mates. Highly suitable tank companions for Eureka Red Peacock Cichlids include Other Peacock Cichlids, provided that a ratio of one male to every two females is maintained to mitigate dominant behaviour.
Additionally, species such as Plecos, larger peaceful Barbs, Rainbow Sharks, Red Tail Sharks, Red Eye Tetras, Botia Loaches, and Synodontis Catfish are considered compatible choices. Conversely, avoiding housing these Cichlids alongside aggressive species like Bettas, Tiger Barbs, and most other non-aggressive Cichlid species is recommended.
Eureka Red Peacocks thrive in an aquatic environment that emulates the conditions of their native Lake Malawi. Water quality is of paramount importance, as deteriorating water quality represents the primary cause of stress in aquarium fish.
These species greatly appreciate adequately oxygenated water, while excessively strong currents are not preferred. Furthermore, they have a tendency to create waste, thus necessitating an effective filtration system capable of managing the additional biological load.
The substrate should consist of sand or fine gravel, and the presence of numerous rocks is crucial for creating caves and passageways that allow the fish to establish territories or seek shelter.
Eureka Red Peacocks are hardy fish; however, like all Lake Malawi Cichlids, they are susceptible to Malawi bloat, a condition primarily triggered by stress. Minimizing stress and maintaining a stable and consistent tank environment are key factors in promoting the health of your Eureka Red Peacocks.
The male Eureka Red Peacock Cichlids exhibit an exquisite appearance, characterized by a striking red body adorned with vibrant blue and black stripes. Additionally, their faces display a light metallic blue colour extending from just past their pectoral fins down to their tails. The lower edge of their dorsal fin, pelvic, anal, and the lower half of their tail fin also feature a captivating shade of red.

Sexual Dimorphism
Distinguishing between male and female Eureka Red Peacock Cichlids is a relatively straightforward task. The development of vibrant light metallic blue and red colours characterizes male specimens. Moreover, males tend to exhibit a slightly larger size compared to their female counterparts, accompanied by a "pointed" dorsal fin and anal fin that are both slightly longer. Conversely, females retain a pale grey colouration and possess more rounded fins in their overall appearance.

Natural Habitat
Eureka Red Peacock Cichlids originate from the Lake Malawi region, specifically observed in locations such as Nkudzi, Monkey Bay, Nankumba, Domwe Islands, and Otter Point. Lake Malawi, situated in eastern Africa, serves as their native habitat.
Within this aquatic ecosystem, these cichlids predominantly inhabit areas distinguished by warm water temperatures, sandy and rocky substrates, and pristine, unpolluted waters. The presence of freshwater vegetation, notably eelgrass, further contributes to their natural habitat and ecological niche.
Breeding
The breeding process of Eureka Red Peacock Cichlids can be characterized as a relatively straightforward procedure. These mouth-brooding fish typically reach sexual maturity at around nine months of age.
To initiate the breeding of Eureka Red Peacock Cichlids, it is recommended to establish a dedicated breeding tank that meets specific environmental requirements. Essential considerations include maintaining a water temperature of 82°F, providing a sandy substrate, and incorporating multiple caves to serve as breeding sites.
Careful selection of one healthy male and up to four healthy females is advised, followed by their transfer to the designated breeding tank. Upon introduction to the breeding tank, the male will establish his breeding territory and select a suitable cave for habitation.
Through a distinctive courtship behaviour characterized by rapid lateral movements, the male seeks to attract the attention of the females. Once a receptive female joins the male, they will engage in breeding activities within the chosen cave, during which the female deposits her eggs in a nest. Subsequently, the remaining females should be returned to their regular aquarium habitat.
After fertilization by the male, the female assumes the role of collecting and carrying the eggs within her mouth. She will remain inside the cave for a period of up to 28 days, diligently guarding the developing eggs until they hatch.
Typically, a brood of approximately 12 to 15 fry will emerge from the eggs. To ensure the survival of the offspring, it is advisable to remove the parents from the breeding tank to prevent them from consuming their progeny.
Providing appropriate nourishment for the newly hatched fry is crucial for their growth and overall well-being. Feeding them with suitable sustenance, such as brine shrimp or infusoria, will support their development.
Once the offspring reach a size of approximately 2 inches or longer, they can be safely reintroduced to the original tank to join the larger population of Eureka Red Peacock Cichlids.
It is important to note that all Aulonocara species have the potential to hybridize. To avoid hybridization, keeping only males or maintaining a single species of Aulonocara in the aquarium is recommended.
Diet & Feeding
In their natural habitat, Eureka Red Peacock Cichlids exhibit an opportunistic feeding behaviour, displaying a versatile dietary preference that encompasses a wide range of food sources found in the substrate. Their natural diet consists of zooplankton, insects, larvae, algae, crustaceans, and plant matter.
When tending to the nutritional needs of Eureka Red Peacock Cichlids in a captive setting, it is crucial to provide a diet that replicates this natural diversity. This can be achieved by offering a combination of high-quality fish food flakes, live or frozen brine shrimp, algae wafers, and vegetables such as blanched spinach and lettuce.
To ensure a healthy feeding routine, it is advisable to provide a small amount of food to the peacock cichlids two or three times a day, ensuring that the quantity offered is sufficient for approximately two minutes of feeding. Any uneaten food should be promptly removed from the tank to prevent disruptions to the water chemistry.
It is important to be aware of certain food items that should be avoided when feeding Peacock Cichlids, as they pose risks to their health, colouration, and overall well-being. Specifically, mammal meat and tubifex worms should be excluded from their diet to minimize the potential for Malawi bloat and preserve their vibrant appearance.
