How is a clown fish commensalism?

Clownfish are an example of commensalism, a type of symbiotic relationship in which one species benefits while the other is neither harmed nor benefited. In the case of clownfish, they live in close association with sea anemones, which provide them with protection from predators. The clownfish, in turn, provide the sea anemones with food by attracting prey with their bright colors and enticing movements. Additionally, the clownfish produce a mucus that helps to clean and protect the sea anemone's tentacles, which further benefits the sea anemone.
