Maylandia lombardoi, commonly known as the Kenyi Cichlid, is a vibrant and popular species of African cichlid from Lake Malawi. Known for its striking coloration and dynamic behavior, Kenyi Cichlids are a favorite among cichlid enthusiasts. However, they are also known for their aggressive nature, which requires careful consideration when planning an aquarium community.

Kenyi Cichlids undergo a dramatic color change as they mature. Juveniles start with a blue or pale blue color, with faint vertical stripes, making them quite attractive. As they age, males transform into a bright yellow with faint vertical bars, while females typically remain blue throughout their lives. This sexual dimorphism in coloration is quite pronounced and adds to the visual appeal of keeping these fish.

In terms of aquarium care, Kenyi Cichlids require a setup that closely mimics the rocky environments of Lake Malawi. Their tank should have plenty of rocks and caves to provide necessary hiding spots and to help diffuse aggression by allowing territorial establishment. The substrate should be sand or fine gravel, suitable for their natural digging behaviors. Due to their territorial and aggressive nature, it is advisable to keep Kenyi Cichlids in a species-specific tank or with other Malawian cichlids that can withstand their aggression.

Water conditions need to be maintained with high quality, reflecting the alkaline nature of their natural lake habitat. The pH should be kept high, and the water should be hard with a stable temperature typical for tropical fish. Regular water changes and robust filtration are crucial to deal with the waste produced by these relatively large and active fish.

Diet-wise, Kenyi Cichlids are omnivorous but require a diet that leans more towards vegetable matter to prevent malawi bloat, a common health issue in cichlids that consume too much protein. Their diet should include high-quality cichlid pellets, spirulina, and vegetable-based foods, supplemented occasionally with live or frozen proteins like brine shrimp or daphnia.

Breeding Kenyi Cichlids can be relatively straightforward in the right conditions. They are mouthbrooders, with the female laying eggs and then picking them up in her mouth to incubate them until they hatch. Males can be particularly aggressive during this time, defending their territory fiercely.

Conservation and responsible fishkeeping are essential when it comes to species like the Kenyi Cichlid. While they are not currently endangered, their popularity in the aquarium trade necessitates sustainable practices to ensure their populations in Lake Malawi are not impacted by excessive collecting.

Overall, Maylandia lombardoi offers an exciting challenge for the experienced aquarist. Their bright colors, interesting behaviors, and specific care requirements make them a captivating, albeit challenging, addition to the home aquarium.
