Clown Fish Facts and Information

Clown fish, or anemonefish, are small eye-catching marine fishes. They inhabit coral formations in the Red Sea, GBR Australia, the Pacific and the Indian Oceans.

They are bottom dwellers. That means they exist close to the seabed of shallow tropical reefs and sheltered lagoons. Clown fish thrive best in sea anemones which they inhabit for protection and food.

Around 28 clownfish species belong with the genus with a scientific name of Amphiprioninae. But, their characterization is with the fish family Pomacentridae.

Anemonefish Facts: The largest clown anemonefish can reach sizes up to 18 centimeters (seven inches). But, the smallest of the clown fish species barely achieve a length of 11 centimeters (four inches). Clownfish are often called anemonefish. It is because of their symbiotic relationship with their host, the sea anemone.

Clown Fish Habitat Facts

Clownfish are reef-dwelling species, preferring warm water coral reef environments. Clownfishes inhabit a single sea anemone in colonial groups. It generally includes a dominant breeding male and a female with several younger males.

The false clownfish are easy to recognize by their beautiful chromatic reddish orange body with white patches or bands. In fact it was the clown fish species which got popularized in the 'Finding Nemo' movie made for children.

But, it is only the taxonomy Amphiprion percula which gets regarded as the true clownfish. They have subtle differences in shape and preferred habitats.

Clownfish Symbiosis

Interdependent symbiosis benefits both the clownfish and the anemone. They co-exist for feeding and for protection. The fish takes up residence with its host anemone. But, it carries out an elaborate dance and acclimates beforehand. It does so by caressing the anemone tentacles with different body parts.

The mutuality helps both parties. The clown fish drives off intruders and preens its host by removing parasites. They both enjoy relative safety from predators and get food scraps in exchange.

Anemone tentacles are poisonous to some fish. But, the clownfish has a thick layer of mucus on its body. That makes it immune to the venom of the fish-eating anemone's lethal sting.

Clown Anemonefish Diet

Clown anemonefish are omnivores which means they will eat other animals or plants. They feed most on undigested food from their host. They also eat small drifting zooplankton in the water column. Their diet can include tunicate larvae, copepods, and an occasional anemone's tentacle. Amphiprion perideraion species primarily feed on algae.

Water pollution worldwide threatens their natural habitat. Even so, clownfishes are not currently considered to be an endangered species. The fact that almost all clownfish fertilized eggs reach adulthood is the main reason for their stable population in the wild.

Other interesting facts about all clown fish eggs is that they all hatch as males. Yet, the dominant male changes sex to become female after the group female dies.
