Body Shape: Their bodies are characterized by a slender and elongated form, often featuring a slightly arched back.
Fins: The dorsal fin is positioned towards the back and is elongated, while the anal fin typically exhibits a prominent triangular shape.

Female Epiplatys fasciolatus puetzi:

Female Puetz’s Lyretail Killifish typically display less vibrant coloration compared to the males. They often showcase more subdued shades of red or orange. Females are generally smaller in size, falling within a size range similar to that of males.
Their fins are usually less colorful and more transparent than those of the males.

Caring for Epiplatys fasciolatus puetzi in Captivity

Providing suitable care for Epiplatys fasciolatus puetzi in a home aquarium is essential to ensure their well-being and to preserve their stunning coloration. Here are the key factors to consider when setting up an aquarium for these fish:

1. Aquarium Setup:

Tank Size: Although Puetz’s Lyretail Killifish is a small fish, it’s important to provide them with adequate space to swim and exhibit their natural behaviors comfortably. A tank with a capacity of 10 to 20 gallons is suitable for a small group of these fish.
Substrate: Utilize a fine-grained substrate such as sand, which mimics their natural habitat and allows them to sift through it in search of food.
Aquatic Plants: These fish thrive in densely planted tanks. Include a variety of live plants such as Java Moss, Hornwort, and Anubias. These plants not only offer shelter but also contribute to maintaining water quality.
Décor: Incorporate driftwood, rocks, and other hiding places to create an environment that provides security and natural aesthetics.

2. Water Parameters:

Temperature: Maintain the water temperature within the range of 73°F to 80°F (23°C to 27°C) to ensure the well-being of your Epiplatys fasciolatus puetzi.
pH Level: Aim for a slightly acidic pH level ranging from 6.0 to 7.0.
Water Hardness: Keep the water moderately soft, with a dGH (degree of general hardness) of 5 to 15.

3. Water Quality:

Regular water changes are crucial to maintain pristine water quality. A weekly water change of 20-30% is a good practice to remove accumulated waste and ensure the health of your fish.

4. Filtration:

Use a gentle filter to avoid strong currents that could stress the fish. A sponge filter is an excellent choice, providing biological filtration without creating excessive water movement.

5. Tank Mates:

Epiplatys fasciolatus puetzi is generally peaceful but can exhibit territorial behavior, particularly during breeding. They coexist well with other small, non-aggressive species such as tetras, rasboras, or small catfish. It’s advisable to avoid keeping them with fin-nipping species.

6. Feeding:

Epiplatys fasciolatus puetzi is primarily carnivorous, and their diet should encompass high-quality flake food, live or frozen brine shrimp, daphnia, and other small aquatic invertebrates. Offering a varied diet is essential for their overall health and coloration.

7. Behavior:

Epiplatys fasciolatus puetzi is known for its lively and active behavior. They are skilled jumpers, so ensure that the tank has a secure lid to prevent any escapes.

8. Lighting:

Moderate lighting is sufficient for these fish. It should replicate the dappled light they would receive in their natural habitat due to the presence of aquatic plants.

Breeding Epiplatys fasciolatus puetzi

Breeding Epiplatys fasciolatus puetzi can be an exciting and rewarding endeavor for aquarists interested in conserving this species and observing their intriguing breeding behavior. Here’s a step-by-step guide to successfully breed these fish:

1. Breeding Tank Setup:

Create a separate breeding tank equipped with fine-leaved plants such as Java Moss or spawning mops. These plants provide ideal locations for the fish to deposit their eggs and for the fry to seek shelter.

2. Pairing:

Select a well-conditioned male and female to introduce to the breeding tank. Courtship behavior will ensue, with the male displaying his vibrant colors to attract the female.

3. Spawning Process:

Epiplatys fasciolatus puetzi is an egg-laying species. The female will lay her eggs among the plant leaves or substrate. After spawning, it is essential to promptly remove the adults from the breeding tank to prevent them from consuming the eggs.

4. Incubation Period:

The eggs will hatch in approximately 10 to 14 days, with the incubation period influenced by water temperature. It is important to monitor the water conditions and maintain optimal parameters during this crucial phase.

5. Fry Care:

Once the fry hatch, they will initially feed on microscopic organisms. Providing them with infusoria or specialized fry food is essential for their survival and growth. As they develop, you can transition their diet to baby brine shrimp and finely crushed flakes.

6. Water Quality:

Consistently monitor and maintain water quality in the breeding tank, ensuring that the conditions remain pristine and conducive to the growth of the fry.

Conservation Status of Epiplatys fasciolatus puetzi

As of my knowledge cutoff date in January 2022, specific conservation information for Epiplatys fasciolatus puetzi was limited. However, like many other aquatic species, these fish face habitat loss and potential threats due to environmental changes and pollution. To support the preservation of Puetz’s Lyretail Killifish and other fish species, aquarists should act responsibly by sourcing fish from reputable and sustainable sources, thereby avoiding contributions to the depletion of wild populations.

In conclusion, Epiplatys fasciolatus puetzi, the Puetz’s Lyretail Killifish, is a unique and visually captivating addition to any freshwater aquarium. Whether you are an experienced aquarist or a newcomer to the world of aquarium keeping, these fish offer a visually striking and engaging experience that can be cherished for years to come. By understanding their general characteristics, natural habitat, specific care requirements, and the intricacies of breeding, you can provide these fish with an environment that allows them to thrive, exhibit their full splendor, and contribute to the preservation of this remarkable and beautiful species.
