Clownfishes or anemonefishes (genus Amphiprion) are saltwater fishes found in the warm and tropical waters of the Indo-Pacific. They mainly inhabit coral reefs and have a distinctive colouration typically consisting of white vertical bars on a red, orange, yellow, brown or black background. Clownfishes developed a symbiotic and mutually beneficial relationship with sea anemones, on which they rely for shelter and protection from predators. In turn, clownfishes will protect the anemone from anemone-eating fish, as well as clean and fan them, and attract beneficial microorganisms with their waste.

Clownfishes are omnivorous and mostly feed on plankton. They live in groups consisting of a breeding female and male, along with some non-breeding individuals. Clownfishes have a size-based dominance hierarchy with the female ranking at the top, followed by the breeding male and then the largest non-breeder and so on. When the female disappears, the breeding male changes sex and takes her place while the others move up the hierarchy. During reproduction, the female deposits eggs on a rock near their anemone, and the male fertilises them. After hatching, clownfishes disperse into the open ocean as larvae, eventually settling on the bottom and searching for an anemone host as juveniles.

The recognisable colour patterns and social nature of clownfishes have contributed to their popularity. They are featured in the Disney/Pixar film Finding Nemo (2003) and are sought after in the aquarium trade. The ocellaris clownfish ranks among the most commonly traded marine fish. Many captive clownfish were taken from the wild and this has led to their decline. Clownfishes are more numerous in marine protected areas, where collecting is forbidden. Other threats to populations include global warming which causes ocean warming and acidification.
