The Leleupi Neolamprologus, scientifically known as Neolamprologus leleupi, is a popular and attractive species of cichlid fish found in Lake Tanganyika, which is one of the African Great Lakes. These fish are known for their striking appearance and interesting behaviors. Here are some key characteristics and information about the Leleupi Neolamprologus:

1. **Appearance**: Leleupi cichlids are known for their vivid coloration. They typically have bright yellow to orange bodies, which makes them stand out in an aquarium. They also have elongated bodies with pointed fins and a relatively large mouth.

2. **Size**: Leleupi cichlids are a relatively small species of cichlid. They usually reach a maximum size of around 4 to 5 inches (10 to 13 centimeters) in length.

3. **Habitat**: In their natural habitat of Lake Tanganyika, Leleupi cichlids are found in rocky areas with crevices and caves. They use these hiding spots for protection and breeding.

4. **Behavior**: These cichlids are known for their territorial and somewhat aggressive behavior, especially during the breeding season. They establish territories around caves and rocks and can be quite protective of their chosen area. However, they are generally less aggressive than some other cichlid species from Lake Tanganyika.

5. **Diet**: Leleupi cichlids are omnivorous, which means they eat a varied diet. In the wild, their diet includes small invertebrates, zooplankton, and algae. In the aquarium, they can be fed a combination of high-quality pellets or flakes and occasional live or frozen foods like brine shrimp or bloodworms.

6. **Aquarium Setup**: When keeping Leleupi cichlids in an aquarium, it's essential to recreate their natural rocky habitat. Provide plenty of caves, crevices, and hiding places using rocks and decorations to mimic their preferred environment. The substrate should be fine sand or gravel.

7. **Water Parameters**: These cichlids prefer water conditions that resemble those of Lake Tanganyika. Aim for a pH level between 7.8 and 9.0, and maintain a water temperature between 75-80°F (24-27°C). Lake Tanganyika is known for its alkaline and hard water, so it's essential to replicate these conditions in the aquarium.

8. **Breeding**: Leleupi cichlids are known to be monogamous and form pair bonds. They typically lay their eggs in caves or crevices and guard them fiercely. If you want to breed them, provide appropriate hiding spots for the female to lay her eggs, and make sure the male and female are compatible. After hatching, the parents will continue to protect and care for the fry.

Overall, Leleupi Neolamprologus cichlids are a stunning and intriguing species for experienced cichlid enthusiasts. They require careful attention to water quality, appropriate tank setup, and compatible tank mates due to their territorial nature. When kept in a well-maintained aquarium, they can be a rewarding addition to your freshwater fish collection.
