Clownfish or Anemonefish, are the subfamily Amphiprioninae of the family Pomacentridae. There are currently 27 species, of which one is in the genus Premnas and the rest are in the subfamily's type genus Amphiprion. The other pomacentrids are called damselfish.
Clownfish are native to wide ranges of the warm waters of the Pacific; some species ranges overlap others. Clownfish are not found in the Atlantic. Clownfish live in a mutual relationship with sea anemones. Once an anemone has been adopted, the clownfish will defend it vigorously. However, clownfish in an aquarium environment can exist very well without an anemone.
The anemone is required in nature because reef life is dangerous for small, brightly colored fish with very poor swimming abilities; in an aquarium lacking predators it is not needed. For this reason, Clownfish never stray far from their host. In an aquarium, where they don't have to forage for food, it is very common for Clownfish to remain within 6-12 inches of their host for an entire lifetime.
