Tank Requirements

The White Lamprologus (Altolamprologus calvus) is native to Lake Tanganyika, Africa, where it inhabits rocky shorelines. A tank setup that mimics this natural habitat is essential for their well-being. A minimum tank size of 120 liters (30 gallons) is recommended, with additional space required if keeping a pair or community. The water should have a pH range of 8-8.9 and hardness between 9-19°N (160.71-339.29 ppm), maintaining a temperature between 23-25°C (73.4-77°F).

It’s important to provide plenty of rocks, caves, and crevices for hiding spots, as these cichlids are territorial and require secure spaces. The substrate should ideally be sand or fine gravel, resembling their native environment. Since Lake Tanganyika is characterized by stable water conditions, it’s crucial to maintain high water quality and stability in the aquarium. A reliable filtration system is necessary, and partial water changes should be conducted regularly to ensure the health and comfort of the fish.

Tankmates

The White Lamprologus is a peaceful cichlid that can coexist with other peaceful species from Lake Tanganyika, provided there is enough space to establish territories. Ideal tankmates include:

• Fairy Cichlid (Neolamprologus brichardi)
• Masked julie (Julidochromis transcriptus)
• Slender cichlid (Cyprichromis leptosoma)

When housing White Lamprologus with other species, ensure that the tank has enough caves and territories for each fish to prevent competition and stress. Avoid keeping them with overly aggressive or much larger cichlids that could outcompete or intimidate them.

Food and Feeding

The White Lamprologus is carnivorous, requiring a protein-rich diet. In the wild, they are predators that often feed on the eggs of other fish. In an aquarium setting, they will accept a variety of flakes, pellets, and live or frozen foods such as brine shrimp, bloodworms, and daphnia. High-quality cichlid pellets are an ideal staple, and occasional feedings of live or frozen treats help ensure their health and vibrant coloration.

Feed them once or twice a day, offering only as much food as they can consume within a few minutes. This helps prevent overfeeding and water quality issues. Providing a varied diet helps maintain their immune system and ensures proper growth.

Sexing

Sexing Altolamprologus calvus becomes more apparent as they mature. Males are generally larger and exhibit longer, more flowing anal and dorsal fins compared to females. Females are smaller and tend to have a rounder body shape, especially when preparing to spawn.

Breeding

White Lamprologus are cave spawners, and the breeding process can be quite fascinating. Females lay their eggs inside a small cave or shell, which the male cannot fully enter. Instead, the male fertilizes the eggs by releasing sperm at the cave or shell opening, and the female fans the eggs to ensure successful fertilization. Both parents participate in guarding the eggs, with the female staying close to the nest and the male defending the perimeter.

The eggs typically hatch within 10 days, and it is advisable to move the shell or cave, along with the female, to a separate rearing tank before the fry hatch. This helps protect the young fish from potential predation in the main tank. Once the fry have absorbed their yolk sacs, they can be fed infusoria or finely crushed flakes. As they grow, newly hatched brine shrimp can be introduced to their diet.

Lifespan

With proper care, Altolamprologus calvus can live for over 10 years, making them a long-term addition to an aquarium.

Origin

White Lamprologus are endemic to Lake Tanganyika, Africa, where they are found among rocky crevices and caves. This natural environment influences their behavior, diet, and breeding habits in captivity.

Short Description

The White Lamprologus, or Altolamprologus calvus, is known for its elongated body shape, slow growth, and unique breeding behavior. They are available in various color variations, including white, black, and yellow. These cichlids are slow-growing and may take up to two years to reach full maturity, making them a rewarding yet long-term commitment for aquarists.

Their peaceful nature makes them suitable for community setups with other Lake Tanganyika species, provided the aquarium is spacious enough to accommodate their territorial needs. Their carnivorous diet and predatory instincts add to their unique appeal, making them an interesting species for experienced cichlid keepers.
