Is a clownfish fish or mammal?

A clownfish is a fish. It belongs to the family Pomacentridae, which includes damselfish and clownfish. Clownfish are found in the warmer waters of the Indian and Pacific Oceans. They are small fish, typically growing to a length of 10-15 centimetres. Clownfish are brightly coloured, with various patterns of orange, white, and black. They live in close association with sea anemones, which provide them with protection from predators. Clownfish are also known for their ability to form symbiotic relationships with anemones. The clownfish provides the anemone with food and protection, while the anemone provides the clownfish with shelter and protection from predators.
