Pale Usisya Aulonocara (Aulonocara steveni)

At A Glance

Identity And Taxonomy

Aulonocara steveni is the care anchor for this listing. FishBase treats Pale Usisya Aulonocara as a Lake Malawi species and notes it from the Kande Island area. Some taxonomy references and aquarium trade names treat related Usisya peacocks around the Aulonocara stuartgranti complex, so old supplier wording can vary. That is why the older Haplochromis steveni wording remains as historical/source context, not as the main scientific name.

For customers, the practical point is simple: this is a Lake Malawi peacock cichlid, not a soft-water community fish. It belongs in a hard, alkaline African cichlid aquarium with suitable space, filtration and companions.

Natural Habitat

FishBase describes Aulonocara steveni among sediment-covered rocks, feeding on soft-bodied invertebrates. That habitat sits between open sand and rocky shelter, which is typical of many peacock cichlids. In the aquarium, this translates into a sand or fine-gravel base, secure rock structures and open swimming space rather than a cramped wall of rocks.

The Usisya-style visual appeal is part of the page's value. Males can show a strong blue head and warm yellow to orange body tones as they mature, while females and juveniles are more subtle. Good lighting, clean water and a calm hierarchy help the fish show its best colour.

Aquarium Size And Layout

The current sale size is a juvenile size. For long-term care, plan around a mature peacock cichlid. A 300 litre aquarium is a sensible minimum for a small group or a mixed peacock/hap arrangement, with a long footprint preferred over a tall narrow tank. More space gives males room to display without constantly pinning females or weaker tank mates into corners.

Use sand or smooth fine gravel, rock piles for territories, and open areas through the front and centre. Secure the rockwork before adding substrate if the layout is heavy. Strong filtration, steady oxygenation and regular water changes matter because Malawi cichlid aquariums are active, well-fed systems.

Water Parameters

Keep the water hard, alkaline and stable. A practical target is 23-28C, pH 7.5-8.5 and 10-30 dGH. Petra's supplier data gives 24-26C, pH 7.5-8.5 and 10-30 dGH, so aiming for the middle of that range is sensible when possible.

Avoid sudden swings. If your tap water is soft or acidic, prepare the mineral strategy before the fish arrives. Aragonite, suitable Malawi buffers or remineralising salts can help, but stability is more important than chasing a perfect number every day.

Feeding

FishBase notes feeding on soft-bodied invertebrates, and aquarium care should follow that pattern. Use a quality Malawi cichlid pellet as the base, then vary with frozen or live foods such as mysis, brine shrimp, daphnia, cyclops and insect larvae. A little vegetable or spirulina content is fine as part of a balanced cichlid diet, but the page should not frame this fish as a plant-grazer.

Feed modest portions that are eaten quickly. Overfeeding can dull colour, raise nitrate and create aggression around the feeding area. A settled fish should become confident at feeding time without needing heavy meals.

Behaviour And Temperament

Pale Usisya Aulonocara is calmer than many mbuna, but it is still a cichlid with hierarchy and territory. Males can become pushy with similar-looking males or when breeding. Females and juveniles are usually less intense, but they still need shelter and room to move away from attention.

For the best display, keep one male with several females when space allows, or choose a carefully planned all-male Malawi display where colours and body shapes are not too similar. Avoid mixing several similar Aulonocara males in a small aquarium.

Compatibility

Good tank mates include other appropriately sized Malawi peacocks, calmer haps and suitable Synodontis catfish in a hard-water setup. Choose companions that share similar water needs and are robust enough for an African cichlid aquarium without being overly aggressive.

Avoid tiny community fish, shrimp, delicate long-finned species, soft-water fish, very aggressive mbuna in cramped tanks, and any fish that looks so similar that it invites constant male rivalry. Compatibility depends on tank size, aquascape and sex ratio as much as species name.

Colour, Display And Visual Appeal

The exact source image shows the classic mature-male appeal: a vivid blue face and upper body with warmer yellow-orange tones through the flank. Juveniles and females are usually less bright, so the customer should expect colour to improve with maturity, diet, water quality and social confidence.

Use a darker background, pale sand and open swimming lanes to make the colour stand out. Clear glass and good white-balanced lighting help the blues read cleanly rather than muddy. This is one of those fish where husbandry and presentation genuinely affect how impressive the page and the aquarium feel.

Breeding Notes

Like other Malawi peacocks, this fish is best treated as a maternal mouthbrooder. Males display and hold territories, females carry eggs and fry in the mouth, and a calm group structure gives breeding behaviour a better chance of happening without excessive stress.

If breeding is the goal, avoid hybrid risk by keeping clear locality/line records and not mixing closely related or similar-looking Aulonocara forms. This matters for responsible cichlid keeping and for the long-term value of the fish.

Who This Fish Suits

This listing suits aquarists who already keep, or are ready to set up, a Lake Malawi aquarium. It is a good choice when you want a peacock cichlid with colour, manageable temperament and interesting natural foraging behaviour, provided the tank is large enough and the tank mates are chosen carefully.

It is not the right choice for a soft-water planted community, a small beginner tank, a shrimp aquarium or a peaceful nano setup. The best buyer is someone planning a proper hard-water cichlid system from the start.

Buying And Delivery Notes

Each live-fish order should be checked against the live stock and variant information shown on this page. The size options represent sale sizes, not final adult size. Use the care table above to plan the permanent aquarium before choosing a variant.

UK live-fish delivery terms, packing days and arrival support are handled by the current checkout and delivery policy rather than fixed promises inside this description. That keeps the page accurate when weather, stock status or courier timing changes.

Sources Checked

Care notes were checked against FishBase for Aulonocara steveni, Fishipedia husbandry guidance, Petra supplier data for the current SKU group, and general Lake Malawi peacock-cichlid aquarium practice. Where sources differ, this listing uses conservative long-term planning rather than the smallest possible juvenile setup.
