Neolamprologus tretocephalus, commonly known as the Five-bar Cichlid, is a striking species of freshwater fish endemic to Lake Tanganyika in Africa. This species belongs to the cichlid family, renowned for its diverse and colorful members that exhibit a wide range of behaviors and adaptations. The Five-bar Cichlid is particularly appreciated for its bold appearance, characterized by five distinct vertical bars on a light blue to white background, making it a visually captivating addition to the aquarium.

Typically reaching a moderate size, Neolamprologus tretocephalus is well-suited for a species-specific setup or a larger community aquarium with other Lake Tanganyika cichlids. They are known for their territorial behavior, especially during breeding, which should be taken into consideration when planning tank mates and aquarium layout. This species thrives in a rocky habitat that allows for the establishment of territories and provides hiding places, mimicking the rocky substrates found in their natural lake environment.

Creating an optimal environment for the Five-bar Cichlid involves replicating the biotope of Lake Tanganyika as closely as possible. This includes a setup with plenty of rocks and caves to provide essential hiding spots and territories. The substrate should consist of sand or fine gravel, and the water conditions should mimic the alkaline, hard water of their native habitat, with a high pH and temperature that reflects the tropical climate of the lake.

The diet of Neolamprologus tretocephalus is omnivorous, with a natural inclination towards consuming a variety of foods, including invertebrates and plant matter. In captivity, their dietary needs can be met with high-quality cichlid pellets or flakes, supplemented with live or frozen foods such as brine shrimp, bloodworms, and daphnia. Offering a mix of dietary items not only ensures they receive all the necessary nutrients but also promotes vibrant health and coloration.

Breeding Neolamprologus tretocephalus can be a fascinating experience for aquarists, as they exhibit monogamous pair bonding and provide parental care to their offspring. They are substrate spawners, laying eggs in the shelter of rocks or caves, where both parents actively participate in guarding and tending to the eggs and fry. Providing optimal water conditions, a nutritious diet, and an stress-free environment can encourage spawning behavior.

Caring for the Five-bar Cichlid requires attention to maintaining a stable and clean environment, with regular water changes and effective filtration to ensure the health and well-being of these fish. Their territorial and sometimes aggressive nature towards conspecifics and other tank mates should be carefully managed through thoughtful aquarium design and selection of compatible species.

In summary, Neolamprologus tretocephalus, or the Five-bar Cichlid, offers aquarists the opportunity to keep a beautiful and behaviorally interesting species from Lake Tanganyika. While their care requires attention to their dietary, environmental, and social needs, the rewards include the enjoyment of their striking appearance and the enriching experience of observing their complex behaviors and interactions within the aquatic setting.
