What Do Clown Killifish Eat? A Tiny Predator’s Diet
Clown killifish primarily consume tiny live foods such as infusoria, micro worms, and newly hatched brine shrimp, although they can also be trained to accept high-quality flake food and frozen foods in a community aquarium setting.
Introduction: The Allure of the Clown Killifish
The clown killifish ( Epiplatys annulatus ) is a captivating and diminutive freshwater fish, originating from the densely vegetated and acidic waters of West Africa. Their small size (typically reaching only 1.5 inches) and vibrant coloration make them a popular choice for nano tanks and dedicated killifish enthusiasts. However, successfully keeping these delicate fish requires a thorough understanding of their dietary needs. What do clown killifish eat? It’s a crucial question for ensuring their health and longevity.
The Natural Diet of Clown Killifish
In their natural habitat, clown killifish are ambush predators, patiently waiting to snap up unsuspecting prey. Their diet primarily consists of:
- Insect larvae: Mosquito larvae, midge larvae, and other tiny aquatic insects are a staple.
- Small crustaceans: Daphnia, copepods, and other micro-crustaceans contribute to their protein intake.
- Algae: While not a primary food source, clown killifish may occasionally graze on algae.
- Infusoria: In the wild, these tiny organisms are a continuous food source.
Adapting the Diet to Captivity
Replicating the natural diet of clown killifish in a home aquarium can be challenging, but it’s certainly achievable. The key is to offer a variety of small, high-quality foods that meet their nutritional requirements.
- Live Foods:
- Infusoria: An essential first food for fry (newly hatched killifish).
- Micro worms: Easy to culture and a readily accepted food source.
- Vinegar eels: Similar to micro worms, but smaller.
- Newly hatched brine shrimp (NHBS): A nutritious and readily available option.
- Daphnia: A good source of protein and fiber, but may be too large for very young fry.
- Grindal worms: Larger than micro worms, suitable for adult clown killifish.
- Frozen Foods:
- Baby brine shrimp: A convenient alternative to hatching live brine shrimp.
- Cyclops: Small and nutritious, suitable for both fry and adults.
- Daphnia: Frozen daphnia can be a good option if live daphnia are unavailable.
- Dry Foods:
- High-quality flake food: Crush into small pieces for easy consumption. Look for flake food specifically formulated for small tropical fish.
- Micro pellets: These are ideal for adults.
Feeding Schedule and Quantity
Clown killifish have small stomachs and require frequent feedings. A general guideline is to feed them small amounts two to three times per day. Watch your fish closely to ensure they are consuming the food offered. Uneaten food should be removed promptly to prevent water quality issues. Overfeeding is a common mistake that can lead to health problems.
Ensuring Nutritional Balance
Providing a varied diet is crucial for ensuring that clown killifish receive all the necessary nutrients. Relying solely on one type of food can lead to deficiencies. A combination of live, frozen, and dry foods is ideal.
Common Mistakes in Feeding Clown Killifish
- Feeding too much food: Leads to poor water quality and obesity.
- Feeding foods that are too large: Clown killifish have small mouths and cannot consume large pieces of food.
- Relying solely on dry food: Clown killifish thrive on live and frozen foods, which provide essential nutrients and stimulate their natural hunting instincts.
- Ignoring the needs of fry: Newly hatched killifish require very small foods, such as infusoria.
- Neglecting water quality: Uneaten food can quickly pollute the water, so regular water changes are essential.

The Benefits of a Well-Balanced Diet
A well-balanced diet is essential for the health, coloration, and breeding success of clown killifish. Proper nutrition supports a strong immune system, vibrant colors, and active breeding behavior. Healthy killifish are also more resistant to disease.
How to Introduce New Foods
When introducing a new food to your clown killifish, start with a small amount and observe their reaction. If they readily consume the food, you can gradually increase the quantity. If they reject the food, try offering it again at a later time, or mix it with a food they already enjoy.
Conclusion: Nurturing Your Tiny Treasures
What do clown killifish eat? Ultimately, the answer lies in understanding their natural feeding habits and replicating them as closely as possible in captivity. By providing a varied diet of small, high-quality foods, you can ensure the health, happiness, and longevity of these captivating little fish. Remember that a little bit of extra care goes a long way in keeping them thriving.
Frequently Asked Questions (FAQs)
What is the best first food for clown killifish fry?
The best first food for clown killifish fry is infusoria. These microscopic organisms are small enough for the tiny fry to consume and provide essential nutrients for their development. You can easily culture infusoria at home using various methods, such as rice water or banana peel infusions.
Can I feed my clown killifish only flake food?
While clown killifish can be trained to accept flake food, relying solely on it is not ideal. Flake food often lacks the essential nutrients and amino acids found in live and frozen foods. Supplementing their diet with live or frozen foods will significantly improve their health and coloration.
How often should I feed my clown killifish?
Clown killifish have small stomachs and require frequent feedings. A general guideline is to feed them small amounts two to three times per day.
Are clown killifish picky eaters?
Clown killifish can be somewhat picky, especially when it comes to accepting new foods. It’s essential to offer a variety of options and be patient when introducing new foods to their diet. Persistence and observation are key.
Can I overfeed my clown killifish?
Yes, overfeeding is a common mistake that can lead to health problems and poor water quality. Be sure to feed only the amount of food they can consume within a few minutes and remove any uneaten food promptly.
What are micro worms, and how do I culture them?
Micro worms are tiny nematodes that are an excellent food source for small fish fry. They are easy to culture in a simple container using a substrate such as oatmeal or bread soaked in water. The worms will reproduce rapidly, and you can harvest them by simply placing a piece of glass or plastic on the surface of the culture and collecting the worms that crawl onto it.
How do I hatch brine shrimp?
Hatching brine shrimp is relatively simple. You will need brine shrimp eggs, a container, saltwater, and an air pump. Follow the instructions on the brine shrimp egg package for specific details. Newly hatched brine shrimp are an excellent source of protein and essential fatty acids.
What are the signs of a malnourished clown killifish?
Signs of malnutrition in clown killifish include loss of color, lethargy, weight loss, and fin clamping. If you notice any of these signs, reassess their diet and make sure they are receiving adequate nutrition.
Is it safe to feed my clown killifish insects I find outdoors?
It is generally not recommended to feed your clown killifish insects found outdoors, as they may carry parasites or pesticides that could harm your fish. It is better to stick to commercially available live foods or culture your own.
Do clown killifish eat algae?
While clown killifish are primarily carnivorous, they may occasionally graze on algae. However, algae should not be considered a primary food source.
How can I improve the coloration of my clown killifish?
A diet rich in carotenoids can significantly improve the coloration of your clown killifish. Carotenoids are found in foods such as brine shrimp, daphnia, and certain types of flake food.
What water parameters are ideal for clown killifish?
Clown killifish prefer soft, acidic water with a pH between 6.0 and 7.0. The temperature should be maintained between 72°F and 78°F (22°C and 26°C). Regular water changes are also essential for maintaining good water quality.
