Clown Killifish are petite creatures, typically growing to a maximum length of around 1.5 inches (4 centimeters). Their growth rate is relatively swift, with juveniles reaching maturity in just a few months. This quick development means you’ll be able to witness the fascinating transformation of your tiny fry into fully-fledged, dazzling adults in no time.

Tank Size

Despite their small stature, these exuberant fish thrive in a spacious environment that allows them to swim and explore freely. A 10 gallon (38 liter) tank is the minimum recommended size to ensure their wellbeing, with larger tanks being even better if you plan on housing multiple fish or introducing tankmates.

Water Parameters

In order to keep your Clown Killifish healthy and thriving, it’s essential to maintain optimal water parameters. These fish prefer soft, slightly acidic water with a pH level between 5.5 and 7.0. The water temperature should be kept between 72°F and 78°F (22°C-26°C), while the hardness should range from 2 to 12 dGH.

Diet

Clown Killifish are carnivorous by nature, with their diet mainly consisting of small, live or frozen foods. They have a voracious appetite for brine shrimp, daphnia, and bloodworms, as well as high-quality, protein-rich flake or pellet food. Providing them with a varied diet ensures they receive the necessary nutrients to maintain their vibrant colors and overall health.

Housing Requirements and What to Put in Their Tank

Creating an ideal environment for your Clown Killifish involves more than just the right water parameters. A well-decorated tank with plenty of hiding spots will make them feel secure and comfortable. Consider adding live plants, driftwood, and rock formations to mimic

their natural habitat. Floating plants are especially appreciated, as they provide cover and help to diffuse the light, replicating the dappled sunlight of their native African waters.

Behavior and Temperament

Clown Killifish are peaceful and timid by nature, making them a joy to observe as they navigate their aquatic world. Males can sometimes display mild aggression towards each other, particularly when competing for the attention of females. However, this behavior is rarely harmful and adds to the dynamic atmosphere of your tank. In general, these fish are active swimmers and tend to spend most of their time near the surface, where they hunt for food and interact with their surroundings.

Breeding

hese captivating fish exhibit unique breeding habits, making their reproduction process fascinating to observe. This comprehensive guide will walk you through the necessary steps to breed Clown Killifish successfully, ensuring that you have all the essential information to create the ideal environment for them to spawn.

Step 1: Set up a separate breeding tank

A dedicated breeding tank is essential for successfully breeding Clown Killifish, as it provides a controlled environment that allows you to cater to their specific requirements. A tank of 5 to 10 gallons (19-38 liters) should suffice for this purpose. The breeding tank should be set up with the following parameters:

• Water temperature: 72-78°F (22-26°C)
• pH level: 5.5-7.0
• Water hardness: 2-12 dGH

Add a sponge filter to ensure gentle water flow and maintain water quality. Dim lighting conditions are preferable, as they mimic the fish’s natural habitat and create a more comfortable environment.

Step 2: Create the ideal breeding environment

The breeding tank should be furnished to provide suitable conditions for spawning. This includes:

• Substrate: A bare-bottom tank is recommended, as it makes it easier to spot and collect the eggs.
• Floating plants: Clown Killifish tend to deposit their eggs on the underside of floating plants or leaves. Suitable options include Java Moss, Water Sprite, or spawning mops.
• Hiding spots: Provide driftwood and rock formations to create a sense of security for the fish and encourage spawning behavior.

Step 3: Condition the breeding pair

Before introducing the breeding pair into the breeding tank, condition them with a high-quality, protein-rich diet for 1-2 weeks. This helps to improve their overall health and ensures they are in optimal condition for breeding. Feed them live or frozen foods such as brine shrimp, daphnia, and bloodworms, up to 3 times a day.

Step 4: Introduce the breeding pair into the breeding tank

Once the breeding pair has been conditioned, introduce them into the prepared breeding tank. It is advisable to introduce the female first, followed by the male a few hours later. This will allow the female time to acclimate and explore the tank before the male’s arrival.

Step 5: Monitor the spawning process

After introducing the breeding pair into the breeding tank, monitor their behavior closely. The male will engage in an elaborate courtship dance to entice the female. Once she is receptive, the female will deposit her adhesive eggs on the underside of floating plants or leaves. The pair may spawn multiple times over several days.

Step 6: Remove the adults from the breeding tank

Following spawning, it is crucial to remove the adult fish from the breeding tank to prevent them from preying on the eggs or newly hatched fry. Transfer the adults back to their main tank and ensure that their needs are met to help them recover from the breeding process.

Step 7: Care for the eggs and fry

Clown Killifish eggs usually hatch within 10-14 days. During this period, maintain the water parameters and monitor the eggs for any signs of fungus. If any fungus is observed, carefully remove the affected eggs to prevent it from spreading.

Once the eggs hatch, the fry will be extremely small and will require infusoria or other microscopic foods for the first week or two. As the fry grow, you can gradually introduce them to larger foods such as newly hatched brine shrimp or microworms.

Step 8: Grow out the fry

As the fry grow, continue to provide them with a balanced diet and maintain ideal water parameters. Perform regular water changes to keep the water clean and ensure optimal growth. Gradually transition them to a diet of finely crushed flake food or micro pellets, along with live or frozen foods such as brine shrimp and daphnia.

Step 9: Monitor the fry’s development

Monitor the growth and development of the fry, keeping an eye out for any signs of illness or stress. Provide adequate hiding spots and maintain appropriate water conditions to support their overall health and wellbeing.

Step 10: Introduce the juvenile Clown Killifish to the main tank

When the fry have reached a size of about 0.5 inches (1.3 cm), they can be considered juveniles and are ready to be introduced to the main tank or a larger grow-out tank. Before adding them to the main tank, ensure that it is a suitable environment for the juveniles to coexist with the adult fish and other tankmates.

Acclimate the juveniles to the main tank’s water parameters gradually, using the drip acclimation method. This process involves slowly adding small amounts of the main tank’s water to the container holding the juveniles over the course of 1-2 hours. This will help the juveniles adjust to the new water conditions and minimize stress during the transition.

Once the juveniles have been acclimated, gently introduce them into the main tank and monitor their behavior to ensure they are integrating well with the other fish. Congratulations, you have successfully bred and raised Clown Killifish!

Tankmates

When it comes to selecting tankmates for your Clown Killifish, it’s important to choose other peaceful, similarly-sized fish to maintain harmony in the tank. Suitable companions include small Tetras, Rasboras, and Corydoras, which share similar temperaments and water requirements. Avoid housing Clown Killifish with larger, aggressive species, as these may view your vibrant little clowns as a potential meal.

Geographic Range and Natural Habitat

The Clown Killifish is native to West Africa, where they can be found in countries like Guinea, Liberia, and Sierra Leone. They inhabit slow-moving streams, swamps, and shallow pools, often in heavily vegetated areas. These lush, plant-filled environments provide ample cover for the small fish, allowing them to hide from predators and hunt for food.

Their natural habitat is characterized by soft, acidic water and the water in these regions is often stained with tannins from decomposing leaves and vegetation, which gives it a dark, tea-like appearance. This environment not only provides the Clown Killifish with ample hiding spots but also contributes to their unique coloration.

Discovery and Classification

The Clown Killifish was first described in 1915 by George Albert Boulenger, a Belgian-British zoologist who specialized in the study of fish and reptiles. Boulenger’s immense contributions to the world of ichthyology and herpetology have earned him a place as one of the most important scientists in these fields.

Boulenger named the species Epiplatys annulatus, placing it in the family Aplocheilidae. This family, commonly known as killifish, comprises over 1,200 species of fish found in freshwater habitats around the world. The genus name, Epiplatys, is derived from the Greek words “epi” meaning “above” and “platys” meaning “flat” – a reference to the fish’s unique dorsal fin placement, which sits higher on the body than other killifish species.

Clown Killifish, as their common name suggests, are indeed the jesters of the aquatic world, with their striking colors and playful nature. They owe their vibrant appearance to their unique habitat, which has influenced their development over time. The vibrant red and blue bands on their fins act as a form of disruptive coloration, helping them blend in with the dappled sunlight and shadows in their natural environment.
