Origin

The Slender Cichlid (Cyprichromis leptosoma) originates from the deep, rocky waters of Lake Tanganyika in Africa. This lake is known for its high water hardness and alkaline pH, both of which are essential to replicate in the aquarium to ensure the health and well-being of these cichlids. In their natural habitat, they inhabit open water, forming large shoals near rocky outcrops.

Tank Requirements

To keep Slender Cichlids healthy, a minimum tank size of 150 liters (40 gallons) is recommended for a group of at least 12 fish. They prefer an environment that mimics the open waters of Lake Tanganyika, so provide plenty of swimming space with rock structures placed along the tank's perimeter. Avoid overcrowding the tank to maintain peaceful interactions among the group.

The water should be kept within a pH range of 7.8-8.9, with a hardness of 18-30°N (321.43-535.71 ppm), reflecting the alkaline and mineral-rich conditions of their natural habitat. A temperature range of 22-25°C (71.6-77°F) is ideal for these cichlids. Use a substrate of smooth sand or fine gravel to create a natural-looking environment and to prevent injuries to the fish.

Install a gentle filtration system to maintain excellent water quality, as Slender Cichlids are sensitive to fluctuations in water parameters. Weekly water changes of 20-30% are recommended to keep the water conditions stable. These fish thrive in tanks with subdued lighting, which can be achieved by using floating plants that provide shade and create a more natural ambiance.

Tankmates

Slender Cichlids are peaceful and can be housed with other non-aggressive fish from Lake Tanganyika. Suitable tankmates include:

• Fairy Cichlid (Neolamprologus brichardi)
• White Lamprologus (Altolamprologus calvus)
• Masked Julie (Julidochromis transcriptus)

It is best to avoid housing them with larger, more aggressive cichlid species, as this can cause stress and territorial disputes. Providing plenty of space and hiding spots will help maintain a peaceful tank environment and reduce potential conflicts.

Food and Feeding

Slender Cichlids have small mouths and require regular, small meals. A varied diet is essential to keep them in top condition. High-quality flake food and brine shrimp are readily accepted, along with other small foods like plankton and glass worms. Feed them two to three times a day in small portions to mimic their natural feeding habits and prevent overfeeding.

Supplement their diet with occasional treats of live or frozen foods to enhance their coloration and overall health. Since they are mid-water feeders, make sure that the food is offered in small, easily consumable pieces to avoid choking or digestive issues.

Sexing

Sexing Slender Cichlids can be done by observing the coloration of their fins. Males usually display vibrant yellow coloration in their fins, while females are more subdued in color but are still attractive with their subtle shades.

Breeding

Slender Cichlids are mouthbrooders, and their breeding behavior is fascinating to observe. The female initiates the breeding process by nudging the male and moving her mouth near his vent to catch his sperm. She will then lay her eggs in mid-water, quickly swimming backwards to collect the eggs in her mouth. This process is repeated several times, laying 3-4 eggs each time until the spawning is complete.

The female will carry the eggs in her mouth for about 3 weeks, during which time she will refrain from eating. It is important to provide a stress-free environment during this period to ensure the health of both the female and the fry. Once the fry are released, they are large enough to accept the same food as their parents, including finely crushed flakes and baby brine shrimp.

Lifespan

With proper care and a stable environment, the lifespan of Cyprichromis leptosoma can range from 5 to 8 years, making them a long-term commitment for dedicated aquarists.

Short Description

The Slender Cichlid is known for its peaceful nature and schooling behavior. In the wild, they form large shoals and swim above rocky outcrops, a behavior that can be replicated in the aquarium by keeping them in groups of at least 12. Unlike many African cichlids, they prefer the open water above rockwork, which helps to relax other tankmates and adds dynamic movement to the aquarium.

These fish are relatively easy to care for as long as their specific water requirements are met. They are best suited for a community tank with other peaceful species from Lake Tanganyika. Their unique breeding behavior and vibrant coloration make them an attractive addition to any freshwater aquarium.
