About & Origin
Like Redbird, Yellowbird is a two-tone Malawi peacock cichlid (Aulonocara sp.) strain — bright yellow body, contrasting blue face — bred for a sharp colour break rather than a single saturated hue, which makes the pair of "bird" strains stand out from the solid-colour Marf and Peacock lines.
Aulonocara forage over sand and mixed rock/sand habitat along Lake Malawi's shoreline, sensing buried invertebrates with a pore-covered snout — worth leaving genuine open sand in the tank rather than covering the floor entirely in rock.
Colour is male-only and develops with age and territory-holding, as with every peacock strain; females and juveniles stay silvery-grey, and the yellow/blue split takes several months to fully come in on a young male.
Aulonocara peacocks are maternal mouthbrooders: after spawning, the female collects the fertilised eggs in her mouth and carries them — without eating — for roughly three to four weeks until the fry are large enough to swim and feed independently. In a mixed-sex group this happens readily without any special intervention, and holding females can be left in the main tank or moved to a breeding trap if you want to maximise fry survival, since other tankmates will happily eat any fry that wander off unsupervised.
When choosing individuals, look for a fish with clear eyes, an even, undamaged fin edge, and — in males — colour that's already showing rather than a washed-out juvenile pattern, since colour intensity in adulthood is difficult to predict from a very young fish. Peacocks are also prone to the same Malawi bloat and internal parasite issues as other rift lake cichlids if kept on a high-protein or poor-quality diet, so a stable, appropriate diet from the start matters more for long-term health than tank decor.
Requirements
Standard Malawi peacock requirements apply: 200+ litres (55+ gallons) for a small group with one male, semi-aggressive but calmer than mbuna, African cichlid pellets plus frozen brine or mysis shrimp, rockwork broken into distinct territories with open sand left for foraging, and slow drip acclimation for new arrivals.
Stocking this strain specifically: Yellowbird's yellow/blue pattern reads clearly different from solid-colour peacocks even to a territorial male, which makes mixed-strain stocking with Marf or solid Peacock lines more straightforward than pairing two solid-colour males of similar hue.
Sexing: males show the full yellow body and blue face once mature; females and juveniles stay silvery-grey.
Diet and colour: a quality African cichlid pellet as the daily base, with frozen brine shrimp or mysis worked in a couple of times a week, supports both general health and the yellow tone's brightness -- foods with natural carotenoid content genuinely help maintain vivid colour over the fish's lifetime rather than being purely cosmetic marketing. Avoid feeder fish and high-fat foods, both linked to the bloat and digestive issues Malawi cichlids are prone to.
Territory and group size: a single male with several females is the standard stable arrangement; two Yellowbird males in the same tank will contest territory even in a large setup, so if keeping multiple males, pair each with a visually distinct strain instead, or provide enough separate rockwork territories that they rarely need to interact.
Compatibility
Water & Care Conditions
- pH: 7.8–8.6, hard and alkaline like the rest of the peacock range
- Water hardness: 10–20 dGH (200–350 ppm)
- Temperature: 24–28°C (75–82°F)
- Water changes: 25–30% weekly with strong filtration
On this two-tone strain, watch for the yellow/blue boundary blurring or the blue face looking washed out — both are early, visible cues worth checking against water quality before other symptoms appear.
New arrivals can take several weeks to settle and show full pattern; a persistently dull or clamped-fin fish beyond that window is worth investigating. Keep ammonia and nitrite at zero once cycled.
Getting the water right: tap water in many areas runs softer and more neutral than this species needs -- a remineralizing buffer, crushed coral worked into the filter, or a dedicated Rift Lake salt mix are all reliable ways to hold the hard, alkaline range consistently rather than hoping tap water is close enough. Owning a basic pH and hardness test kit is worth it specifically for this species, since fish kept persistently outside range show up as chronic low-grade problems -- faded colour, poor appetite -- well before anything acute.
Given consistent care, Malawi peacocks including this strain commonly live 6-10 years, a substantially longer commitment than many community fish and worth factoring into any stocking decision.
