Character
Daily temperament
Amphiprion clarkii is diurnal. It is a protandrous hermaphrodite, meaning the animal is first male and then becomes female, and lives in a harem where hierarchy is very marked and based on constant physical aggression from the dominant over the subordinate individuals. It is territorial and bound to its anemone. It is not a strong swimmer; it always remains in close proximity to its host, straying only a few meters to seek food. Mutualism is the term that defines the type of associative relationship between sea anemone and clownfish. Indeed, a protective mucus, developed from the larval stage, is spread over the fish's body and immunizes it against the stinging venom produced by the anemone. The fish finds shelter within the anemone. In return, the clownfish can serve as bait to attract prey to the anemone and remove parasites from it. It can also defend its anemone against attacks from certain fish that can graze on the anemone, such as butterflyfish. It was also demonstrated in 2025 by a study from Osaka Metropolitan University that the fish shares food with its anemone, thereby contributing to its growth.
Physical

Amphiprion clarkii is a small fish that can reach 15 cm in length. Its body appears stocky, oval in shape, laterally compressed and with a rounded profile. Its coloration shows many variations depending on geographic location. The base colors of the body are black on the dorsal area and orange-yellow on the ventral area.
