Aulonocara Korneliae - UK

If you are searching for tropical fish for sale UK and want something more distinctive than the usual starter species, Aulonocara korneliae deserves a close look. Commonly sold as the Blue Gold Peacock Cichlid or Chizumulu Peacock, this Lake Malawi cichlid combines metallic blue, gold and violet tones with the alert, inquisitive personality that makes peacock cichlids so rewarding to keep. It reaches around 10 cm as an adult, can live up to 10 years with proper care, and suits aquarists who want an African cichlid UK setup with colour, movement and character. For many fishkeepers, it sits in the sweet spot between a true beginner fish and a demanding specialist species, making it a strong choice for anyone building a hard-water display.

In practical terms, this is not a fish for a tiny desktop aquarium or a small tropical fish tank with heater. It needs stable water, room to establish territories, and a properly planned Malawi layout. Questions like what temp is tropical fish tank, what should tropical fish tank temperature be, and what size tank for tropical fish matter a lot here, because peacocks show their best colour and behaviour only when conditions are right. See our detailed photos showing the body depth, face colour and finnage of this species in a mature display. If you want to buy live fish online uk, buy tropical fish UK, or compare peacock cichlids for sale uk before choosing, this species offers brilliant colour without the constant aggression seen in many Mbuna.

Where Do Aulonocara korneliae Come From? Natural Habitat Explained

Aulonocara korneliae is endemic to Lake Malawi cichlid UK collections because its wild home is Lake Malawi in East Africa, specifically around Chizumulu Island. That restricted range is one reason the species feels special in the hobby. Unlike fish collected from broad river systems, this cichlid evolved in a very specific rocky and sandy shoreline environment where water is clear, mineral-rich and consistently alkaline.

In the wild, peacock cichlids are famous for hunting small invertebrates in and over the substrate. They use sensory pores around the head to detect movement in sand, then pick out tiny prey items. That natural feeding style explains why a sandy base matters so much in captivity. It also explains why this fish behaves differently from algae-grazing Mbuna. If you have wondered what tropical aquarium fish eat snails, this is not a dedicated snail-control species; it is better thought of as a sand-sifting omnivore with a strong preference for quality prepared foods and meaty supplements.

The wider tropical fish tank ecosystem of Lake Malawi is stable, oxygen-rich and low in dissolved organics. That is why problems such as why is tropical fish tank cloudy, why my tropical fish tank is cloudy, why does my tropical fish tank smell or why is my tropical fish tank going green usually point to setup or maintenance issues rather than anything about the fish itself. A healthy Malawi display should look bright, crisp and open, not swampy or overgrown.

Some keepers compare specialist Malawi stock with general retail options like all pond solutions tropical fish, tropical fish pond uk or even searches such as tropical fish pond royal oak. In reality, Aulonocara korneliae is a warm, indoor freshwater species and not a pond fish. It belongs in a heated aquarium with hard, alkaline water. For aquarists deciding on a blue gold peacock cichlid or alternative species, this fish stands out for its refined colour and more measured aggression compared with many rock-dwelling Malawi cichlids.

How to Set Up the Perfect Tank for Aulonocara korneliae

The best blue gold peacock cichlid Malawi tank setup starts with space. While the listed minimum is 150 litres, that is really the floor for a carefully planned group. For a single male with three or more females, or for a mixed peacock display, 180-240 litres is far more practical. If you are asking blue gold peacock cichlid minimum tank size, blue gold peacock cichlid tank size, what size tropical fish tank or what tank do you need for tropical fish, think in terms of footprint more than height. A long tank gives subordinate fish room to move away from dominant individuals.

A 90 cm tank is the minimum length I would consider for a quiet species group, and a 100cm tropical fish tank is better if you want more than one male line of sight. A 50cm tropical fish tank or 60cm tropical fish tank is too cramped long term for this species. An 80cm tropical fish tank may work temporarily for juveniles, but adults need more room. For many homes, a 90cm tropical fish tank with strong filtration and rockwork is the sensible starting point.

Tank Size Requirements

This species is often described as suitable for blue gold peacock cichlid for beginners, but that only applies when the tank is large enough and correctly stocked. A single specimen can be kept in a species-focused setup, but peacocks usually show more natural behaviour in a harem group. If you are planning a blue gold peacock cichlid for large tank display, mixing several Aulonocara species should only be done with care to avoid hybridisation and excessive male rivalry.

Water Parameters

The correct blue gold peacock cichlid temperature is 24-28°C, with 25-26°C being a very reliable target for day-to-day care. If you are searching tropical fish temperature, tropical fish tank temperature, temperature of tropical fish tank, tropical fish tank ideal temperature, tropical fish tank best temperature, tropical fish tank temperature range, tropical fish tank water temperature, what temperature should a tropical fish tank be kept at, what temperature should you keep a tropical fish tank or what temperature does tropical fish tank need to be, for this species the answer is simple: keep it stable in the mid-20s Celsius. For UK keepers asking tropical fish tank temperature uk celsius, aim for 25-26°C using a dependable heater.

pH should sit between 7.5 and 8.5, with hardness around 10-25 dGH. If you are wondering what ph for tropical fish tank, what should tropical fish tank ph be, what should my tropical fish tank levels be or what should tropical fish tank levels be, this is a hard-water fish that does not appreciate soft, acidic community conditions. Stable alkaline water is more important than chasing exact decimal points.

Filtration and Heating

Because Malawi tanks are heavily stocked compared with many community aquariums, a strong filter matters. A quality external canister or oversized internal filter works well. Your tropical fish tank filter and heater should be chosen as a pair: filtration for waste processing, heating for stability. A reliable tropical fish tank heater should be sized to the aquarium volume, and the tropical fish tank heater setting should be checked with a separate thermometer rather than trusted blindly. Good tropical fish tank heater position is near filter outflow so warm water circulates evenly. Many keepers planning a tropical fish tank complete setup forget that dead spots behind rockwork can trap waste, so direct flow to keep debris moving.

Substrate, Plants and Decor

Fine sand is ideal. It allows natural foraging and is safer than sharp gravel if fish sift or mouth the substrate. Build stable rock piles directly on the tank base before adding sand, so burrowing cannot undermine them. The classic blue gold peacock cichlid hard water care layout uses open sand at the front, caves and broken rock lines at the back, and plenty of swimming room in the middle water column.

If you are asking what plants for tropical fish tank, use hardy species that tolerate alkaline water and occasional digging. Anubias attached to rock and Java fern on wood or stone can work, though many Malawi keepers prefer a mostly rocky scape. A true blue gold peacock cichlid for planted aquarium setup is possible only with robust plants and careful hardscape design. Keepers using a 90cm tropical fish tank light should avoid overly intense lighting unless balanced by decor, because bright bare tanks can make fish nervous.

What Do Aulonocara korneliae Eat? Complete Feeding Guide

The correct blue gold peacock cichlid diet is varied, controlled and protein-aware. In the wild these fish pick small invertebrates from the substrate, so in captivity they do best on quality cichlid pellets supported by frozen foods such as brine shrimp, krill and occasional spirulina-based foods. Good blue gold peacock cichlid feeding is about balance rather than simply offering the richest food possible.

As a staple, choose a sinking or slow-sinking cichlid pellet formulated for omnivorous African cichlids. This gives consistent nutrition and reduces the risk of digestive trouble caused by random feeding. Supplemental foods can include frozen brine shrimp and krill two or three times per week. Spirulina helps support colour and digestive health, especially in mixed Malawi tanks where not every fish has the same protein needs.

Feeding should be modest: once or twice daily, only what the group clears in under a minute. Overfeeding is one of the fastest ways to trigger tropical fish tank algae, cloudy water and poor health. Uneaten food breaks down into waste, which then contributes to tropical fish tank green algae, tropical fish tank brown algae, tropical fish tank hair algae and even tropical fish tank black hair algae. If you are researching tropical fish tank algae treatment, the first step is almost always feeding less and improving maintenance rather than buying a quick fix.

Because Malawi tanks are often sparsely planted, some keepers wonder about tropical fish tank plant food. Use it only if you truly keep live plants, and dose carefully. Excess nutrients in a rocky cichlid tank can simply feed algae. Likewise, do not rely on tropical fish tank algae eaters or tropical fish tank bottom feeders to solve overfeeding. Most common algae eaters are not ideal companions for peacock cichlids, and many bottom dwellers need different water chemistry.

Time	Food	Amount
Morning	Quality cichlid pellets	Small pinch, eaten in 30-60 seconds
Evening	Pellets or frozen brine shrimp/krill	Light second feed, 2-4 times weekly

Aulonocara korneliae Appearance: Colors, Patterns & Varieties

The Blue Gold Peacock Cichlid Fish is prized for the contrast between metallic blue facial colour, warmer gold to bronze body tones and iridescent highlights that shift with angle and mood. Adult males are the show fish here. As they mature, they develop stronger head colour, cleaner fin edging and a more intense body sheen. Females remain far plainer, usually in subdued silver-brown tones that help them blend into the background.

At around 10 cm adult size, Aulonocara korneliae has the typical elegant peacock shape: laterally compressed body, pointed head, long dorsal fin and smooth, gliding movement through the middle of the tank. The best specimens show a clean profile without pinched flanks, and males should hold fins open when comfortable. If you are reading a blue gold peacock cichlid care guide, strong colour is usually a sign of stable water, low stress and a well-structured environment.

Our photos show the best tones under balanced aquarium lighting rather than heavily edited colour. In person, the effect is often richer than a single image can capture, especially when the fish displays over pale sand and dark rock. This is why many aquarists choose the species for a display tank rather than a mixed community tropical fish uk setup. It simply looks more at home in a dedicated Malawi layout.

Searches like tropical fish shop near me greenville sc are obviously not relevant for UK fishkeepers, but they do reflect how often hobbyists compare online images before buying. When assessing colour, look for body depth, fin condition and alert posture, not just bright saturation. A stressed fish can be digitally colourful in a photo but poor in real life.

What Fish Can Live With Aulonocara korneliae? Compatibility Guide

The key to good compatibility is understanding blue gold peacock cichlid behaviour. This species is semi-aggressive, not relentlessly violent. Males establish display areas and may chase rivals, especially similarly coloured peacocks. Females are usually calmer, but all individuals need space and structure. If you are searching blue gold peacock cichlid compatible fish, blue gold peacock cichlid tank mates, best tank mates for blue gold peacock cichlid or general tropical fish tank mates, think “other hard-water cichlids with similar temperament” rather than peaceful soft-water community fish.

Good companions include other peacock cichlids, selected mild haps and robust catfish such as Synodontis. Suitable examples from our range include Aulonocara Sp Neon Red Calico Peacock, Rubin Red Peacock Cichlid - Aulonocara and Aulonocara kandeense. These are natural comparison points for a blue gold peacock cichlid community tank or mixed peacock setup. If you prefer a more assertive Malawi display, Yellow Elongatus Cichlid - Chindongo Elongatus can work only with caution, as aggressive Mbuna may bully or outcompete peacocks.

Species to avoid include tiny tetras, shrimp and delicate community fish. This is not a fish for the standard community tropical fish uk model, and it is definitely not suitable with fancy invertebrates. If you are wondering what tropical fish clean the tank, what tropical fish keep the tank clean or which tropical fish clean the tank, do not choose tank mates based on cleaning myths. Choose them based on water chemistry, temperament and adult size.

Some hobbyists ask whether a peacock can live with South American cichlids such as Thorichthys Maculipinnis - Elliot'S Cichlid - or Guianacara Dacrya - South American Cichlid. While size and temperament may look similar, the water chemistry and behavioural style are different enough that I would not recommend mixing them long term. Likewise, Tanganyikan species such as Kiriza Yellow Cichlid - Tropheus Moorii or Orange I Blunthead Cichlid - Tropheus have different dietary and social needs.

If you are building a stocking plan and searching malawi cichlids tank mates, blue gold peacock cichlid for community tank or a tropical fish tank mates chart, the safest route is a species-focused peacock group or a carefully chosen Malawi mix with similar aggression levels. Avoid overstocking as a shortcut for aggression control unless you have the filtration and experience to manage it.

Species	Compatible?	Notes
Rubin Red Peacock Cichlid - Aulonocara	✅ Yes	Good match in water chemistry and temperament in a spacious tank.
Aulonocara kandeense	✅ Yes	Works well in mixed peacock setups if male aggression is monitored.
Yellow Elongatus Cichlid - Chindongo Elongatus	⚠️ Caution	More aggressive Mbuna behaviour can stress peacocks in smaller aquariums.
Shrimp and very small fish	❌ Avoid	Likely to be harassed, eaten or stressed by cichlid activity.

How to Breed Aulonocara korneliae: Complete Breeding Guide

Blue gold peacock cichlid breeding is very achievable for aquarists with a stable Malawi setup. This species is a maternal mouthbrooder, which means the female carries the fertilised eggs in her mouth until the fry are developed enough to be released. Breeding difficulty is moderate rather than hard, mainly because success depends on correct group structure, low stress and proper conditioning.

The ideal blue gold peacock cichlid breeding pair setup is actually a harem: one mature male with three or more females. That spreads attention and reduces stress on any single female. If you are asking what do you need for a tropical fish tank, what chemicals do you need for a tropical fish tank or what chemicals do i need for a tropical fish tank for breeding, the answer is less about additives and more about stability. Clean, alkaline water, a mature filter and quality food matter far more than bottles.

Spawning usually begins when the male intensifies in colour and claims a display site over sand or near a flat stone. He will shimmy, circle and try to lead a female to the chosen spot. After spawning, the female picks up the eggs in her mouth. New keepers sometimes panic when they see tropical fish tank eggs or think they have found yellow eggs in tropical fish tank, but with mouthbrooders the eggs are usually not left exposed for long. Instead, you may notice the female stop feeding and hold a fuller throat area.

Incubation commonly lasts around 18-28 days depending on temperature and female condition. During this period, keep stress low and avoid unnecessary netting. Once the fry are released, they can be left with the mother briefly in a quiet species tank, but survival is much higher if they are raised separately. Feed newly free-swimming fry on crushed cichlid food, fine fry foods and freshly hatched brine shrimp.

If you are wondering what is tropical fish tank breeding really about, it is simply controlled reproduction in a stable captive environment. For this species, that means correct blue gold peacock cichlid water parameters, good diet and suitable social structure. Questions like what tropical fish can live in a small tank do not apply here; breeding adults need room and calm.

Aulonocara korneliae vs Similar Species: Which Should You Choose?

Peacock cichlids are often bought on colour alone, but that can lead to stocking mistakes. Comparing species helps you choose a fish that fits your tank size, aggression tolerance and long-term plan. If you are deciding between this fish and another peacock, think about adult colour, group dynamics and whether you want a dedicated species look or a mixed display.

Choose Aulonocara korneliae if you want a manageable Malawi show fish with elegant colour and less chaos than many Mbuna. Choose Aulonocara Sp Neon Red Calico Peacock if you want stronger red tones in a mixed peacock group. Choose Yellow Elongatus Cichlid - Chindongo Elongatus only if you prefer a more aggressive, rock-dominant Malawi setup. For aquarists comparing Blue Gold Peacock Cichlid options, this species is especially appealing when you want a classic peacock body shape with a cooler, more metallic look.

Common Health Problems in Aulonocara korneliae & How to Prevent Them

A healthy fish should be alert, hold its fins open, respond quickly to food and show clear eyes with no excess mucus. Colour will vary with mood and hierarchy, but healthy males should still show a visible sheen even when not fully displaying. Common tropical fish tank diseases in Malawi cichlids include ich, bacterial fin damage, internal parasites and Malawi bloat linked to stress, poor diet or bad water quality.

Most problems start with husbandry. If you are learning how to maintain tropical fish tank, how to keep tropical fish tank clean, how to keep tropical fish tank water clear, how to clean tropical fish tank or even how to clean small tropical fish tank, the answer for peacocks is consistent routine. Test water weekly, remove waste, clean filter media in old tank water and avoid overstocking beyond your filtration capacity. If you are unsure how to test tropical fish tank water, check ammonia, nitrite, nitrate and pH as a minimum.

Water changes are especially important. For those asking how to change tropical fish tank water, replace 25-40% weekly using dechlorinated, temperature-matched water. This is where tropical fish tank water treatment matters: use a conditioner that neutralises chlorine and chloramine, and avoid sudden chemistry swings. If you are setting up from scratch and asking what should tropical fish tank levels be, aim for zero ammonia, zero nitrite and controlled nitrate.

A separate tropical fish quarantine tank is strongly recommended for new arrivals or sick fish. It does not need to be elaborate, but it does need a heater, cover and mature biological filtration. Many disease outbreaks begin when fish are added directly from a retailer into a display tank without observation. Searches like tropical fish shop near me richmond va are irrelevant for UK buyers, but they highlight a real issue: local availability varies, so online fish should be quarantined just as carefully as shop-bought stock.

Understanding Aulonocara korneliae Behavior in the Aquarium

The typical blue gold peacock cichlid behaviour pattern is alert, curious and moderately territorial. These fish spend much of their time in the middle and lower-middle levels, moving in and out of open sand areas while watching tankmates closely. Males become more intense around feeding time and when displaying to females, often deepening in colour and holding their fins wider.

They are not schooling fish in the strict sense, so the idea of blue gold peacock cichlid school size is better understood as social grouping rather than shoaling. The best arrangement is one male with several females, or a carefully managed mixed peacock group in a larger tank. Too many males in a cramped aquarium leads to constant sparring and faded subordinate fish.

Natural behaviour is easiest to see in a tank with open sand, caves, stable water and low background stress. In poorly structured aquariums, peacocks may hide, hover nervously or lash out more often than normal. If you want a fish with visible personality but not nonstop chaos, this species is an excellent middle ground.
