Introduction:

Epiplatys chaperi soillmanni is a remarkable and lesser-known species of killifish that belongs to the family Nothobranchiidae. This fish is native to West Africa, specifically in the region around Cameroon and Nigeria. Like other members of the genus Epiplatys, E. chaperi soillmanni exhibits captivating colors, interesting behaviors, and unique characteristics that make it an appealing choice for aquarium enthusiasts. In this comprehensive guide, we will delve into the world of Epiplatys chaperi soillmanni, examining its natural habitat, physical characteristics, care requirements, breeding behavior, and its place in the aquarium hobby.

Natural Habitat:

Epiplatys chaperi soillmanni is predominantly found in the lush tropical rainforests and wetlands of West Africa, particularly in the southern regions of Cameroon and Nigeria. These fish inhabit various aquatic environments, including seasonal rainforest pools, streams, swamps, and even small rivers. E. chaperi soillmanni has adapted to thrive in habitats that experience seasonal fluctuations in water levels, demonstrating its remarkable resilience and ability to endure challenging conditions.

Physical Characteristics:

1. Size: Adult Epiplatys chaperi soillmanni typically reach a size of 2 to 2.5 inches (5-6.5 cm). Unlike some other killifish species, there is minimal size difference between males and females.
2. Body Shape: This species has a streamlined and elongated body shape, which is typical of killifish. Their dorsal fin is situated towards the back of the body, and their anal fin is relatively short.
3. Coloration: The coloration of E. chaperi soillmanni is one of its most distinctive features. Males are adorned with a striking combination of iridescent blues, greens, and reds, along with intricate patterns of spots and stripes on their body and fins. Females, on the other hand, tend to have a more subdued coloration, often appearing silver or beige.
4. Fins: Both males and females have elegant, translucent fins. In males, the dorsal and anal fins may possess extended filaments, which are more pronounced during courtship displays.

Care Requirements:

Caring for Epiplatys chaperi soillmanni in an aquarium can be a rewarding experience for fish keepers. These fish are generally hardy and adaptable, making them suitable for a range of aquarium setups. Here are key considerations for their care:

1. Aquarium Size: A tank with a capacity of 10 to 20 gallons is suitable for a small group of E. chaperi soillmanni. A larger tank offers more swimming space and facilitates better water quality maintenance.
2. Water Parameters:
   • Temperature: Maintain a temperature range of 72-78°F (22-26°C).
   • pH Level: Aim for a slightly acidic to neutral pH of 6.0-7.0.
   • Water Hardness: Keep water hardness in the range of 5-12 dGH.
3. Filtration: A gentle filtration system is recommended to maintain water quality without creating strong currents that might stress the fish. Provide adequate biological filtration to help process waste.
4. Substrate: Use fine gravel or sand as substrate, as E. chaperi soillmanni occasionally sift through the substrate in search of small invertebrates.
5. Decorations: Mimic their natural habitat with plenty of live or artificial plants, driftwood, and hiding spots. Floating plants can help diffuse light and create shaded areas.
6. Tank Mates: Epiplatys chaperi soillmanni is generally peaceful but may be outcompeted for food by more aggressive tank mates. Suitable companions include small tetras, rasboras, and peaceful dwarf cichlids.
7. Feeding: These fish are omnivorous and accept a variety of foods, including high-quality flake or pellet foods, live or frozen artemia, daphnia, and small insects. A varied diet ensures their nutritional needs are met.

Breeding Behavior:

Breeding Epiplatys chaperi soillmanni can be an exciting and rewarding endeavor for aquarists. These fish exhibit intriguing courtship and breeding behaviors. Here’s how to encourage successful breeding:

1. Male Displays: During courtship, males intensify their colors and display their fin extensions to impress females. They also engage in a courtship dance, which involves chasing and displaying their fins to potential mates.
2. Spawning Site: Provide spawning mops, fine-leaved plants, or spawning mops for the fish to lay their eggs. The eggs are adhesive and will attach to these surfaces.
3. Separation: It’s advisable to set up a separate breeding tank with one male and two or more females. After successful courtship, females will lay eggs, and males will fertilize them.
4. Egg Collection: After spawning, remove the eggs from the breeding tank to protect them from being eaten by the adults. You can gently scrape the eggs off the substrate or plants.
5. Incubation: Transfer the collected eggs to a separate container with water from the parent tank. Keep the water temperature stable and aerated. The eggs will hatch in about 10-14 days.
6. Fry Care: Once the fry hatch, feed them with infusoria, powdered fry food, or microorganisms until they are large enough to accept larger food items.

Conclusion:

Epiplatys chaperi soillmanni is a captivating and vibrant species of freshwater killifish that has gained recognition among dedicated aquarium enthusiasts. With their striking colors, captivating behaviors, and relatively straightforward care requirements, these fish make a splendid addition to aquariums of all sizes and experience levels. Whether you’re interested in observing their mesmerizing courtship displays or undertaking the challenge of breeding these fish, E. chaperi soillmanni offers an enriching and enjoyable experience for fishkeepers.
