3. Understanding African Lamp Eye (Poropanchax normani)
Natural Habitat and Origin
The African Lamp Eye, scientifically known as Poropanchax normani, is native to slow-moving rivers, ponds, and swamps throughout West Africa. These environments are typically warm, with dense vegetation and soft, slightly acidic water. African Lamp Eyes are known for their striking, reflective blue eyes, which shine under light and contribute to their name. In the wild, they form large schools and inhabit the upper to mid-levels of the water column.
Physical Characteristics
African Lamp Eyes are small, slender fish, typically growing to a length of about 1-1.5 inches (2.5-3.8 cm). Their bodies are mostly translucent to pale silver with a subtle iridescence, allowing them to blend into their surroundings. The defining feature of this species is their bright, reflective blue eyes, which create a stunning effect when they move through the water. Their small size and peaceful nature make them an attractive choice for community tanks.
Behavior and Temperament
These fish are peaceful, social, and highly active, thriving best in groups of six or more. African Lamp Eyes are schooling fish that prefer to swim together, offering a visually captivating display when kept in groups. They are generally non-aggressive and do well in community tanks with other small, peaceful species. Providing plenty of cover, such as plants and floating vegetation, helps them feel secure and display their best colors.
Evolutionary History
Part of the family Procatopodidae, the African Lamp Eye is closely related to killifish and shares similar adaptations for life in freshwater habitats. Their reflective eyes may have evolved as a form of communication or to deter predators by appearing larger or more visible in dimly lit waters. Their schooling behavior offers added protection in the wild.
Adaptability
African Lamp Eyes are hardy and adaptable, provided they are kept in stable, well-maintained water conditions. They tolerate a range of water parameters but do best in soft, slightly acidic to neutral water. Sudden changes in water quality or temperature can stress them, so a consistent environment is essential for their health and well-being.
4. Setting Up the Ideal Aquarium
Tank Size and Specifications
A minimum tank size of 10-15 gallons is recommended for a small group of African Lamp Eyes. A larger tank is preferable if you plan to keep a larger school or house them with other species. These active fish need plenty of swimming space, along with areas of cover provided by plants and decorations to help them feel secure.
Water Parameters
The ideal water temperature for African Lamp Eyes ranges from 72°F to 80°F (22°C to 27°C). They prefer slightly acidic to neutral water, with a pH range of 6.0 to 7.5 and a general hardness (GH) of 4-12°GH. Stable water parameters and good water quality are important to prevent stress and disease.
Filtration and Aeration
Effective filtration is crucial to maintain water clarity and quality. Use a filter that creates gentle water flow, as these fish prefer calm to moderately flowing water. Sponge filters, hang-on-back filters, or canister filters with adjustable flow are suitable options. Aeration can be beneficial but should not create strong currents that stress the fish.
Choosing the Right Filter Media
Mechanical media can help trap debris, while biological media supports beneficial bacteria for breaking down waste. Consider using chemical media, such as activated carbon, to remove impurities and keep the water clean.
Substrate and Decorations
A soft substrate, such as sand or fine gravel, works well for African Lamp Eyes and helps create a natural-looking environment. Include dense plant cover, such as live plants, driftwood, and rock formations, to provide hiding places and create shaded areas. Floating plants can diffuse light, making the fish feel more comfortable and enhancing their colors.
Biotope Setup Tips
To mimic their natural habitat, set up a biotope tank with soft substrate, aquatic plants, driftwood, and floating vegetation. This setup encourages natural behaviors and creates a visually appealing, peaceful environment.
Lighting Requirements
Moderate lighting is recommended for African Lamp Eyes. Bright, intense lighting should be diffused with floating plants or decorations to create a more natural setting. Soft, indirect lighting enhances their reflective eyes and helps reduce stress.
Tank Maintenance Schedule
Perform weekly water changes of 20-30% to maintain optimal water quality. Clean the substrate regularly to remove detritus and uneaten food, and rinse filter media as needed (using tank water to preserve beneficial bacteria). Regular maintenance ensures a stable environment, which is crucial for these small, sensitive fish.
5. Diet and Feeding
Natural Diet
In the wild, African Lamp Eyes primarily feed on small insects, larvae, and zooplankton. Their diet consists of tiny invertebrates found in and around the water column, which they capture with precision due to their small size and agility.
Feeding in Captivity
Offer a varied diet that includes high-quality flake foods, micro pellets, and live or frozen foods such as brine shrimp, daphnia, and mosquito larvae. They thrive on a diet that mimics their natural prey, and the inclusion of live or frozen foods will help bring out their best coloration and activity levels.
Special Treats and Enrichment
Occasionally providing live foods like small insect larvae or tiny worms can offer enrichment and encourage natural hunting behaviors. Feeding should be done sparingly and with appropriate portion sizes to prevent overfeeding and water quality issues.
Feeding Schedule
Feed African Lamp Eyes two to three times daily in small portions that they can consume within a few minutes. Their small size and fast metabolism mean they benefit from frequent feedings of easily digestible foods. Monitor their feeding to ensure all individuals are eating well.
Nutritional Tips
Provide a balanced diet that includes a mix of protein-rich live or frozen foods, as well as high-quality flake or pellet foods. A diverse diet helps maintain their health, coloration, and activity. Avoid overfeeding, as excess food can contribute to poor water quality and health issues.
6. Tank Mates and Compatibility
Suitable Tank Mates
African Lamp Eyes are peaceful and do well in community tanks with similarly sized, non-aggressive fish. Suitable tank mates include small tetras, rasboras, guppies, danios, and peaceful dwarf cichlids. Keeping them in a group of six or more helps them feel secure and display their natural schooling behavior.
Species to Avoid
Avoid housing African Lamp Eyes with large, aggressive, or predatory fish that may see them as prey or outcompete them for food. Fast-moving or fin-nipping fish should also be avoided to prevent stress or injury.
Social Structure
African Lamp Eyes are schooling fish and should be kept in groups of at least six individuals. This social structure helps reduce stress, promotes natural behavior, and makes them feel more secure. In larger groups, they exhibit more confident swimming and vibrant coloration.
Managing Aggression
These fish are generally non-aggressive, but they may become stressed or shy if kept in insufficient numbers or with incompatible tank mates. Maintaining a well-structured environment with appropriate companions ensures a harmonious community.
7. Health and Disease Prevention
Common Diseases
Common health issues affecting African Lamp Eyes include ich, bacterial infections, and parasitic infestations. Symptoms to watch for include changes in behavior, loss of appetite, white spots, or fin damage. Keeping water quality high and minimizing stress is crucial for disease prevention.

Provide fine-leaved plants or spawning mops for egg deposition and maintain low light levels to create a more natural environment.
Breeding Process
These fish are egg scatterers and typically spawn in groups, with females releasing eggs that are fertilized by the males. The eggs are scattered among plants or fall to the substrate. After spawning, it is best to remove the adults to prevent predation on the eggs, as they do not exhibit parental care.
Raising Fry
Once hatched, the fry will require very fine foods, such as infusoria or commercially prepared liquid fry food. As they grow, gradually introduce newly hatched brine shrimp or finely crushed flake food. Maintain excellent water quality and gentle filtration to ensure their survival and development.
Parental Behavior
African Lamp Eyes do not exhibit any parental care, and the eggs and fry are vulnerable to predation. Separating the eggs from adults and providing a controlled environment for the fry is crucial for breeding success.
9. Acclimating Your New Fish
Preparation Before Arrival
Ensure that the aquarium is fully cycled and that water parameters match those of the source water as closely as possible. Providing plenty of hiding spots and a stable, calm environment will help reduce stress during acclimation.
Acclimation Steps
The drip acclimation method is recommended for African Lamp Eyes to ensure a gradual transition to new water parameters. Alternatively, float the bag in the tank to equalize temperature, then slowly add small amounts of tank water over 30-60 minutes. This method helps minimize stress and improves the likelihood of a successful acclimation.
Quarantine Procedures
Quarantine all new arrivals for at least two weeks in a separate tank to monitor for signs of illness and prevent disease transmission. Maintain water conditions similar to the main tank to reduce stress during this period.
10. Special Care Considerations
