Clown Killifish: The Banded Panchax

The Clown Killifish, scientifically known as Epiplatys annulatus, is a vibrant and captivating species of fish that is commonly referred to as the Banded Panchax due to its distinct bands of dark brown and tannish-yellow. This small fish, reaching a size of only 1.4 inches (3.5 cm), is particularly known for its striking flame-like tail, which is more prominent in males.

Understanding the breeding habits of the Clown Killifish is essential for successful reproduction. They are annual fish, meaning they complete their life cycle within a year.

Females lay their eggs in plants, and once fertilized, the eggs can be removed and placed in a separate container for incubation.

When it comes to tank setup, creating the perfect environment for Clown Killifish in a nano tank requires attention to detail. A 5-gallon tank is sufficient for these small fish, but it should be densely planted to provide hiding places and simulate their natural habitat. The water parameters should be kept stable, with a pH range of 6.5-7.5 and a temperature of 72-78°F (22-26°C).

Providing a well-balanced diet consisting of high-quality flakes, frozen or live foods will ensure the optimal health of these beautiful fish.
