Kenyi Cichlid Care Guide (Maylandia lombardoi)

The Kenyi Cichlid is a striking African Mbuna from Lake Malawi — bright yellow-gold males, blue-and-black-barred females, and a personality that's pure cichlid attitude. At Tropical Treasures Wyo in Cheyenne, Wyoming, it's one of the most-requested Mbuna for keepers building their first African cichlid tank, mostly because the color difference between males and females is so dramatic.

Kenyis are also one of the most commonly mis-stocked cichlids in the hobby. They're aggressive, they need an Mbuna-only setup, and they're absolutely not community fish. Get the tank size and stocking ratio right and they're hardy, long-lived, and stunning. Get them wrong and you'll lose tank mates within weeks.

This guide covers everything you need to keep Kenyi Cichlids (Maylandia lombardoi) thriving long-term — tank setup, diet, tank mates, sexing, and breeding — based on how we actually keep and ship them.

• Lifespan: 8–10 years with good care
• Temperament: Aggressive and highly territorial
• Care level: Moderate (easy water parameters; difficult social management)
• Minimum tank size: 55 gallons; 75+ gallons strongly preferred

Are Kenyi Cichlids Hard to Keep?

Water-wise, no — Kenyis are hardy and tolerant of typical hard, alkaline freshwater tap water across most of the U.S. Behaviorally, they're one of the more challenging Mbuna because adult males are relentlessly aggressive toward anything yellow (other males, look-alike species, even similarly colored Yellow Labs).

The two factors that decide success are tank size (under 55 gallons is asking for trouble) and stocking ratio (one dominant male to at least three females). Get those right and a Kenyi aquarium should be one of the most colorful displays in the hobby.

Tank Size & Setup

Minimum tank size

• Single male with 3–4 females: 55 gallons absolute minimum, 75 gallons preferred
• Mixed Mbuna community: 75–125 gallons
• Avoid: tanks under 55 gallons — there's not enough territory to disperse aggression

Footprint matters more than height. Mbuna patrol horizontally along the rockwork, so a 4-foot or 6-foot tank gives dominant males room to set territories that don't overlap.

Substrate

Use fine sand or smooth fine gravel. Aragonite or coral sand helps buffer pH upward toward Lake Malawi's natural alkalinity. Sand also lets Kenyis sift naturally and won't injure their gills when they dig.

Aquascape

• Heavy rockwork. Stack flat rocks, slate, or holey rock into caves and territories from front to back. The more line-of-sight breaks, the lower the aggression among territorial males.
• Skip delicate plants. Kenyis dig and uproot most aquarium plants. Anubias and Java fern attached to rocks survive; everything else gets destroyed.
• Open swimming space. Leave the front third of the tank open for active swimming and display.
• Secure decorations. Kenyis dig under rocks. Use egg-crate under your substrate to prevent rock collapses, or stack rocks directly on the glass before adding sand.

Filtration & Flow

Mbuna are heavy bioload freshwater fish — they eat a lot, poop a lot, and produce ammonia fast. Use a filter rated for at least 2× your tank volume; a canister filter or two oversized HOBs is ideal for a 75-gallon Mbuna setup. Strong flow mimics the open Lake Malawi environment they evolved in. For more help choosing, read our aquarium filtration guide.

Heating

Tropical-range heater. A 200–300 watt heater works for a 55–75 gallon. Stable warmth keeps coloration vibrant and immune systems strong.

Water Parameters

Stability matters. A Kenyi kept at a steady pH 8.2 will thrive; one bouncing between 7.6 and 8.4 weekly will stress out fast. Use a quality water conditioner like Seachem Prime on every water change. If your tap water is naturally soft, supplement with crushed coral, aragonite substrate, or a Rift Lake mineral mix. We offer free water testing at our Cheyenne store — bring in a sample.

Diet & Feeding

Kenyi Cichlids are omnivores with strong herbivorous leanings. In the wild, they graze algae and biofilm off rocks ("Mbuna" means "rockfish"), and a too-protein-heavy diet causes Malawi bloat, a frequently fatal digestive condition.

• Staple: high-quality vegetable-based cichlid pellets or flakes (Hikari Cichlid Excel, Northfin Veggie, Omega One Cichlid Veggie Flakes, New Life Spectrum Cichlid)
• Vegetables 2–3× per week: blanched zucchini, spinach, peas, or spirulina flakes
• Protein sparingly: brine shrimp or daphnia once a week max — never bloodworms or beef heart
• Avoid: high-protein cichlid pellets formulated for Central or South American carnivores. They will cause bloat in Mbuna.

Feed small amounts 1–2× per day. Hungry-looking Mbuna are far healthier than overfed Mbuna. For a deeper dive, see our how often to feed your fish guide.

Tank Mates

Kenyis belong in an Mbuna-only setup. They're too aggressive for community tanks, and the dietary differences make them incompatible with most other African cichlid groups.

Great tank mates

• Other Mbuna species with different coloration — Acei, Rusty Cichlid, Red Zebra, Cobalt Blue Zebra
• Synodontis catfish (Synodontis lucipinnis or Synodontis multipunctatus)
• Larger Mbuna in 75+ gallon tanks for proper social structure

Avoid

• Yellow Labs (Labidochromis caeruleus) — males will attack them on sight as competing dominant males
• Other yellow Mbuna species — same coloration equals constant aggression
• Peacock cichlids (Aulonocara) — too gentle, get bullied
• Hap cichlids — different territory needs and feeding behaviors
• South or Central American cichlids — incompatible water parameters and diet
• Community fish, plecos, shrimp, snails — all become victims or food

Risky but possible

Bristlenose plecos. Some keepers mix them with Mbuna successfully in 75+ gallon tanks with plenty of cave structure for the pleco to retreat to. Most plecos eventually get bullied or starve. We don't recommend it for first-time Mbuna keepers.

Male vs. Female: How to Sex Kenyi Cichlids

Kenyis show extreme sexual dimorphism — sexing is one of the easiest in the hobby:

• Adult males turn solid bright yellow-gold as they mature (around 2.5–3 inches). They're slightly larger and have more pointed dorsal and anal fins with distinct egg spots.
• Females stay light blue with vertical dark bars their entire lives — the same juvenile coloration both sexes start out with.

If you bought a tank of "blue Kenyis" and one started turning yellow, that's a dominant male maturing. Females do not change color. If you buy a "harem" from us at Tropical Treasures Wyo, we hand-select 1 male to 3+ females in-store.

Breeding Kenyi Cichlids

Kenyis are maternal mouthbrooders and will breed naturally in a healthy Mbuna tank without intervention.

• Setup: A 1M:3+F harem in a 55+ gallon tank with ample rockwork.
• Spawning: The dominant male displays in a flat-rock territory; the female lays eggs and immediately picks them up in her mouth. The male fertilizes them via "egg spots"— markings on his anal fin that mimic eggs.
• Brooding: The female holds 15–30 eggs (and later fry) in her mouth for 18–25 days, not eating during this period. Her cheeks visibly bulge.
• Fry release: She releases free-swimming fry into the rockwork. Fry are large enough to eat crushed flake and baby brine shrimp from day one.
• Saving fry: Most fry get eaten by tank mates. To raise them, strip the female into a separate tank around day 18 or move the brooding female to a breeder net.

Healthy Kenyi pairs spawn every 4–6 weeks. Local Mbuna keepers will gladly take fry off your hands.

Common Problems & Diseases

• Malawi bloat: swollen belly, stringy white feces, lethargy. Caused by high-protein diet, stress, or bacterial infection. Treat with metronidazole-based medication immediately. Feed only vegetable-based pellets after recovery.
• Aggression-related stress: a Kenyi hiding constantly, with clamped fins or torn fins, is being bullied. Add more rockwork, increase female-to-male ratio, or rehome the aggressor.
• Ich (white spot): common after shipping or temperature drops. Treat with heat (82–86°F) and proper medication. See our Common Fish Diseases guide.
• Fin damage: almost always from tank mate aggression. Identify the bully and fix the social structure rather than treating fins symptomatically.

Tips for Long-Term Success

• Always 1 male to 3+ females. A single male housed with only one female causes relentless harassment.
• Don't mix yellow species. Avoid Yellow Labs, Red Zebras with yellow morphs, and other predominantly yellow Mbuna in the same aquarium.
• Feed vegetable-based pellets. Avoid high-protein foods to prevent Malawi bloat.
• Do 25–30% water changes weekly. Mbuna fish have a heavy bioload requiring frequent aquarium maintenance.
• Buy from a quarantining source. Every Kenyi we sell at Tropical Treasures Wyo is quarantined in-house before shipping to ensure healthy fish.

Frequently Asked Questions

What is the lifespan of a Maylandia lombardoi?

Kenyi Cichlids typically live 8–10 years in a well-maintained freshwater aquarium with stable water parameters and good care.

How big do Kenyi Cichlids get?

Adults reach 5–6 inches. Males are slightly larger and turn solid yellow-gold; females stay light blue with vertical bars.

Are Kenyi Cichlids aggressive?

Yes — highly territorial and one of the more aggressive Mbuna species. They need an Mbuna-only tank, a proper male-to-female ratio, and plenty of rockwork for territory.

What size tank do I need for Kenyi Cichlids?

55 gallons is the absolute minimum for a 1M:3F harem. 75 gallons is strongly preferred and provides space for other Mbuna species as well.

Can I keep Kenyi Cichlids in a community tank?

No. They will harass, kill, or eat community freshwater fish, shrimp, and snails. Kenyis require Mbuna-only aquarium setups.

Why do my female Kenyis not turn yellow?

They never will. Female and juvenile Kenyis remain light blue with vertical bars for life. Only dominant adult males develop the bright yellow coloration.

Can I keep Kenyi Cichlids with Yellow Labs?

Not recommended. Male Kenyis aggressively attack any yellow fish on sight as competing adult males. Yellow Labs will be bullied relentlessly.

Do Kenyi Cichlids need a heater?

Yes. They thrive between 75–82°F. Stable warmth is essential for maintaining vibrant color and a strong immune system.

What is the prettiest dwarf cichlid?

The Kenyi Cichlid is often considered one of the prettiest dwarf cichlids due to its dramatic sexual dimorphism — bright yellow adult males contrasted with blue-barred females — and vivid colors that stand out in any aquarium.
