Maylandia lombardoi is an mbuna with unusual reversed dimorphism: males are golden-yellow while females are bright blue. One of the most aggressive mbuna.
Overview
Maylandia lombardoi is one of the most recognizable mbuna from Lake Malawi, famous for its unusual "reversed" sexual dimorphism. Unlike most mbuna where males are more colorful, lombardoi has it the other way around: males display a rich yellow or golden-orange coloration, while females are bright blue with distinctive black vertical bars. Juveniles of both sexes start life in the blue color phase, with males gradually transitioning to yellow as they mature.
Adults reach 10–12 cm. In the wild, M. lombardoi inhabits the area around Mbenji Island and rocky coastal zones of Lake Malawi, at depths of 5 to 20 meters. As a typical mbuna, the fish leads a bottom-dwelling lifestyle among rocks, feeding on algal biofilm.
The popular trade name "Kenyi Cichlid" has become firmly established for this species in the hobby. A word of caution: despite its attractive appearance, Maylandia lombardoi is one of the most aggressive mbuna, and it is recommended only for aquarists experienced with Malawian cichlids.
Tank Requirements
A group of Maylandia lombardoi requires a tank of at least 200 liters. Given the high aggression level of this species, a larger volume is always better.
Optimal water parameters:
- Temperature: 24–28 °C
- pH: 7.8–8.6
- GH: 10–20
The setup should follow the classic rocky Lake Malawi biotope with abundant rocks, caves, and crevices. The number of hiding spots should significantly exceed the number of fish — this is critically important for reducing aggression. Every fish must be able to hide from the dominant male at any moment.
Substrate should be sand or fine gravel. Lombardoi actively dig through the substrate, especially during spawning, so rocks should be placed directly on the tank bottom rather than on sand for better stability.
Live plants will not survive in a lombardoi tank — the fish will quickly destroy them.
Filtration must be powerful. Mbuna create a serious bioload, and without adequate filtration, water quality will deteriorate rapidly. An external canister filter is the optimal choice.
Feeding and Diet
Maylandia lombardoi is a predominantly herbivorous mbuna, feeding on algal biofilm (aufwuchs) on rocks in the wild.
The aquarium diet should be based on:
- Spirulina-based pellets and flakes — the staple daily food
- Blanched vegetables: zucchini, cucumber, spinach, peas
- Frozen cyclops, daphnia — as supplements to the main diet
- Spirulina tablets
Important: strictly avoid foods high in animal protein (bloodworms, tubifex, meat). Like all mbuna, lombardoi have a long intestinal tract designed for digesting plant matter, and excess protein leads to Malawi bloat — a frequently fatal condition.
Feed 2–3 times daily in small portions. Lombardoi are greedy eaters that easily overeat, so monitor food quantities carefully.
Care and Maintenance
Maylandia lombardoi is a hardy fish in terms of water parameters but extremely demanding when it comes to aggression management. This is the main challenge of keeping this species.
Weekly water changes of 25–30% are mandatory. Monitor nitrate levels — they should not exceed 20 mg/l. Ammonia and nitrites must always be at zero.
The optimal group composition is one male to four or five females. Keeping two males in one tank is only viable in very large volumes (400+ liters) with abundant hiding spots; otherwise fierce conflicts are inevitable.
Watch behavior closely. The dominant male can be extraordinarily aggressive toward subordinates. Signs of critical stress: the fish constantly hides, loses color, refuses food, and has torn fins. In such cases, the victim must be removed immediately.
Tip: when initially stocking the tank, introduce all fish simultaneously. Adding newcomers to an established mbuna group almost always results in their brutal persecution.
Compatibility
Maylandia lombardoi is one of the most aggressive mbuna, which seriously limits the choice of tank mates.
Suitable companions (in a spacious tank):
- Robust mbuna of similar size: Pseudotropheus zebra, Cynotilapia afra, Melanochromis auratus
- Labidochromis caeruleus — a more peaceful mbuna, but agile enough to cope provided there are plenty of hiding spots
Not recommended:
- Species with similar yellow coloration — conflict with the dominant male will be especially intense
- Species with similar blue coloration: Melanochromis johannii (males), Chindongo demasoni — similarity triggers aggression
- Peaceful non-predatory Malawi species: Aulonocara — will be overwhelmed
- Any small or slow-moving fish
Apply the "moderate overstocking" principle to disperse aggression. Filtration must be scaled up proportionally to the number of fish.
Breeding
Maylandia lombardoi is a maternal mouthbrooder, and breeding this species is straightforward. Under good conditions, the fish reproduce regularly.
Spawning is typical for mbuna. The dominant male claims a territory near a chosen rock and intensely displays his golden coloration to attract females. The female lays eggs in small batches, picks them up in her mouth, and approaches the male's anal fin, where bright egg spots (ocelli) trigger fertilization.
The female carries 15 to 40 fertilized eggs in her mouth for 21–28 days. During this period, she completely refuses food and is easily identified by her swollen buccal pouch.
In a community tank, some fry can survive if there are small hiding spots among the rocks. For maximum fry yield, the brooding female can be moved to a separate tank a few days before releasing the fry.
Fry are colored blue with black bars, resembling the females. Males begin changing to yellow coloration at 4–6 months of age — this is one of the most reliable ways to sex growing juveniles. Feed fry with crushed spirulina flakes and baby brine shrimp.
