Common Clownfish


Amphiprion ocellaris

Today's Research for Tomorrow's Oceans

Species Type:


Common Name(s):



Clownfish can grow to be around 4.3 inches long (11 centimeters), with an average weight of 7.06 ounces (200 grams).


Clownfish are omnivorous creatures, feeding on equal parts algae and other animals. Eating the leftovers of their host anemone clownfish will also scavenge for their own algae and small aquatic invertebrates.

Range & Habitat:

Living in the warm waters of the Indian and Pacific oceans, the clownfish typically does not stray from its tropical habitat. They find shelter in anemones nearby.


Clownfish and anemones live in a mutual symbiotic relationship with each other. Clownfish use anemones as shelter from predators while also eating whatever food scraps are left over from the anemone’s previous meal. In return, the clownfish will lure in other fish for the anemone to kill and eat. Their anemone homes can be found in reef communities or lagoons. Social in nature, these fish have no trouble communicating with each other through short sounds. Unlike most other species, female clownfish lay their eggs before the male fertilizes them. According to the International Union for Conservation of Nature’s Red List of Threatened Species, clownfish are listed as Least Concern
