Norman’s Lampeye Killifish Tank Mates: 10 Compatible Species & Care Tips

The scientific name for Norman’s Lampeye Killifish is Poropanchax normani. It was named after John Roxborough Norman, a British ichthyologist who worked at the British Museum of Natural History in the early 20th century. Norman’s Lampeye is a small, peaceful species of freshwater fish. It belongs to the family Poeciliidae, which includes other popular aquarium fish like guppies, mollies, platies and swordtails.

Norman’s Lampeye grows to a maximum size of about 1.2 inches (3 cm) for males and 1.4 inches (3.5 cm) for females. The males are more colorful, with iridescent blue-green scales on their sides that shimmer under aquarium lighting. Females are larger and plumper but less colorful. Both have the signature large eyes of lampeye killifish.

In the aquarium trade, P. normani are sometimes sold under the names Norm’s Lampeye, Norman’s Lampeye Killi, or Blue Lampeye. They make an excellent addition to peaceful community tanks with similarly-sized fish. Norman’s Lampeye do best in heavily planted tanks that mimic their natural habitat. They prefer subdued lighting and dark substrates. Floating plants are appreciated as Norman’s Lampeye like to hang out near the water surface.

As micropredators, Norman’s Lampeye have upturned mouths suited for feeding on small invertebrates and insect larvae at the water surface. In the aquarium, they readily accept most dried, frozen and live foods like daphnia, cyclops, and baby brine shrimp. Feed several small meals throughout the day rather than one large feeding.

Norman’s Lampeye are typically found in the shallow, heavily vegetated edges of slow-moving rivers and streams in West Africa. Their natural range spans from Gambia to Cameroon. They tend to congregate in large groups near the water surface where they hunt for insect larvae and small crustaceans among the vegetation.

What makes Norman’s Lampeye especially interesting is their unusual eye structure. Their eyes are much larger in proportion to their bodies compared to most other fish. This adaptation helps them locate tiny prey in their dimly lit habitats. Under a microscope, their eyes have a complex pattern of reflective layers that look almost like fiber optics!

While Norman’s Lampeye are generally peaceful, the males can be territorial with each other, especially in smaller tanks. For this reason, it’s best to keep them in groups with at least two females for each male. A 10 gallon (38 liter) aquarium could comfortably house 6-8 individuals. Tankmates should be chosen carefully as Norman’s Lampeye may be outcompeted for food by faster, more boisterous fish. Good companions include other West African species like dwarf Pelvicachromis and small Synodontis catfish.

Breeding Norman’s Lampeye is relatively easy but raising the tiny fry can be a challenge. Like other killifish, they scatter their eggs among fine-leaved plants. Providing thick clumps of java moss or spawning mops will encourage breeding behavior. However, the eggs and fry are very sensitive to water conditions. Frequent small water changes and infusoria-grade foods are essential for the first few weeks until the fry are large enough to accept baby brine shrimp.

While Norman’s Lampeye Killifish may not be as popular as their larger killifish cousins, these peaceful micropredators are a joy to observe in a well-planted aquarium. With their shimmering colors, unusual upturned mouths, and oversized eyes, they are sure to catch the attention of both beginning and experienced fish keepers alike. By providing them with a suitably decorated tank and an appropriate diet, you can enjoy watching their natural behaviors as they navigate their tiny world at the water’s surface.

FAQs about Norman’s Lampeye Killifish

How do I acclimate Norman’s Lampeye Killifish to my aquarium?

Acclimation is crucial to prevent shock from sudden changes in water parameters. Float the bag containing your new fish in the aquarium for 15-20 minutes to allow the temperature to equalize. Then, gradually add small amounts of aquarium water to the bag over the course of 30-45 minutes. Finally, gently release the fish into the aquarium.

How often should I feed my Norman’s Lampeye Killifish?

Feed your Norman’s Lampeye Killifish small amounts of food 2-3 times a day. Offering smaller, more frequent meals helps ensure that all fish have access to food and reduces the risk of overfeeding, which can lead to poor water quality.

Can I keep Norman’s Lampeye Killifish in a planted tank?

Yes, Norman’s Lampeye Killifish thrive in heavily planted tanks. Live plants provide hiding spots, help maintain water quality, and create a more natural environment for your fish. Choose plants like Java Moss, Anubias, and Cryptocoryne species that can tolerate the soft, slightly acidic water preferred by these killifish.

How do I prevent my Norman’s Lampeye Killifish from jumping out of the aquarium?

Norman’s Lampeye Killifish are known for their jumping ability, so it’s important to keep a tight-fitting lid on your aquarium. Ensure that there are no gaps around equipment or openings where the fish might escape. You can also lower the water level slightly to create a larger gap between the water surface and the lid.

Can I keep Norman’s Lampeye Killifish with shrimp?

Yes, Norman’s Lampeye Killifish can coexist peacefully with small, peaceful shrimp species like Cherry Shrimp (Neocaridina davidi) or Amano Shrimp (Caridina multidentata). However, keep in mind that very young shrimp or shrimplets may be seen as food by the killifish.

How can I tell if my Norman’s Lampeye Killifish are stressed?

Signs of stress in Norman’s Lampeye Killifish include loss of appetite, lethargy, hiding, rapid gill movement, and a loss of color. Stress can be caused by poor water quality, improper tank mates, or sudden changes in the aquarium environment. If you notice these signs, check your water parameters and make any necessary adjustments.

How often should I perform water changes for my Norman’s Lampeye Killifish tank?

Perform weekly water changes of 10-20% to maintain good water quality. Use a gravel vacuum to remove debris and uneaten food from the substrate. Be sure to treat the new water with a dechlorinator before adding it to the aquarium to remove harmful chlorine and chloramines.

Can I breed Norman’s Lampeye Killifish in my home aquarium?

Yes, breeding Norman’s Lampeye Killifish is possible in a home aquarium setting. Provide a heavily planted tank with a dark substrate and subdued lighting to encourage spawning. The fish will scatter their eggs among the plants, so having fine-leaved plants or spawning mops is essential. Once the eggs hatch, feed the fry infusoria or commercially prepared fry food until they are large enough to accept baby brine shrimp.
