Clownfish, also known as anemonefish, are colorful and playful creatures that have become popular due to their appearance in the beloved film “Finding Nemo.” These small fish are native to the warm waters of the Pacific and Indian Oceans.

If you’re considering keeping clownfish as pets or simply want to know more about their dietary needs, you may be wondering, “What does clownfish eat?” Well, you’re in the right place!

Clownfish are omnivores, which means they eat a variety of foods ranging from plants to small invertebrates.

However, when it comes to clownfish kept in aquariums, their diet may need to be slightly different.

To ensure the health and well-being of your pet clownfish, it’s crucial to provide them with a balanced diet that mimics their natural feeding habits. In this article, we will explore the specific foods these vibrant fish consume and provide some tips on maintaining a nutritious diet for your clownfish. So, let’s dive in!

The Clownfish Diet in the Wild

In their natural habitat, clownfish have a varied diet that consists of algae, plankton, and small invertebrates. Algae are a significant part of their diet, and they feed on both green and brown types of algae. Algae provide essential nutrients and fiber that contribute to their overall health.

Clownfish also feed on various species of plankton, including zooplankton (small animals found in the water) and phytoplankton (microscopic plants). These tiny organisms are abundant in the ocean and serve as a vital food source for many marine creatures.

Additionally, clownfish indulge in small invertebrates, such as copepods and amphipods. These invertebrates are found in and around the anemones that the clownfish call home. Despite their size, these invertebrates offer a protein-rich meal for the clownfish.

The Clownfish Diet in Aquariums

When it comes to feeding clownfish in an aquarium setting, replicating their natural diet is essential. A balanced diet is crucial for their growth, development, and overall well-being. Here are some key components of a nutritious clownfish diet in aquariums:

1. Commercial Fish Food

High-quality commercial fish food formulated for marine omnivores is a great staple diet for clownfish. Look for a food specifically designed for marine fish and ensure it contains a mixture of plant-based ingredients, such as seaweed, as well as protein sources like fish or shrimp. Pellet or flake food can both be suitable options, depending on the size and preference of your clownfish.

2. Algae-Based Supplements

To mimic the algae component of their natural diet, you can supplement their meals with algae-based products. These can come in the form of frozen or dried seaweed sheets or even liquid algae supplements. Some clownfish species, such as the tomato clownfish, have a higher reliance on algae in their diet and may benefit from additional algae-based supplements.

3. Live or Frozen Feeders

Some clownfish may accept frozen or live feeders raised specifically for aquarium use, such as brine shrimp or mysis shrimp. These small invertebrates provide a natural source of protein and can be an excellent addition to their diet. However, it’s essential to ensure the feeders are of high quality and free from any potential diseases or parasites.


So, what does clownfish eat? Clownfish have a diverse diet that includes algae, plankton, and small invertebrates. In aquariums, these colorful fish can be fed with high-quality commercial fish food formulated for marine omnivores, supplemented with algae-based products, and occasionally supplemented with live or frozen feeders. By providing a well-rounded diet that mimics their natural feeding habits, you can ensure the health and happiness of your pet clownfish.

Remember, just like any pet, clownfish require proper care, attention, and a nutritious diet to thrive. By understanding their dietary needs and providing them with a variety of suitable foods, you can create an environment where your clownfish can flourish.

Now that you know what clownfish eat, it’s time to explore the wonderful world of these intriguing and vibrant creatures. Whether you’re an aspiring fish owner or simply fascinated by marine life, clownfish are sure to bring a splash of color and joy into your life!
