Clownfish
Clownfish are small, brightly coloured marine fish in the subfamily Amphiprioninae, also known as anemonefish.
Clownfish are small, brightly coloured marine fish in the subfamily Amphiprioninae, also known as anemonefish. They live in symbiosis with sea anemones in warm tropical waters of the Indian and Pacific oceans, where they are popular aquarium fish and became widely known through films such as Finding Nemo.
Taxonomy
Clownfish are usually placed in the subfamily Amphiprioninae within the family Pomacentridae. Sources differ slightly on the number of recognised species, but most place the group at roughly 28 to 30 species.
Habitat and distribution
These fish live in warm, shallow marine habitats, especially coral reefs and lagoons. Their range includes the Indian Ocean, the Red Sea, and the western Pacific, including areas near Australia and Southeast Asia.
Relationship with sea anemones
Clownfish are named for the sea anemones they inhabit. The relationship is symbiotic: the anemone offers protection, and the fish gain shelter while also helping clean the anemone and remove leftovers.
Appearance and diet
Clownfish are usually small, typically under about 18 cm long, and often have orange bodies with white stripes, though colour varies by species. They eat small invertebrates, algae, zooplankton, and other organic food sources.
Key facts
- Clownfish are small reef fish with bright orange, yellow, red, brown, or black colouring and white bars or markings.
- They live among sea anemones, which provide shelter, while the fish help by eating parasites and leftover food.
- There are about 28 to 30 recognised species of clownfish, depending on the source.
- Most clownfish live in warm, shallow waters of the Indian Ocean, Red Sea, and western Pacific Ocean.
- Clownfish are popular aquarium fish and are strongly associated with the film Finding Nemo.
Clownfish are mainly relevant to Canadian readers through aquariums, marine education, and popular culture, especially their prominence in Finding Nemo and in public aquarium displays.
