![]() There are several theories for how this avoidance is accomplished. In an aquarium, where they do not have to forage for food, it is very common for clownfish to remain within 6 to 12 inches of their host for an entire lifetime.Ĭlownfish and damselfish are the only species of fish which can avoid the potent stings of an anemone. For this reason, clownfish never stray far from their host. The anemone is required in nature because reef life is dangerous for small, brightly colored fish in an aquarium lacking predators it is not needed. Once an anemone or coral has been adopted, the clownfish will defend it. Clownfish live in a mutual relationship with sea anemones, or in some cases settle in some varieties of soft corals or large polyp stony corals. Clownfish are not found in the Atlantic Ocean. The other pomacentrids are called damselfish.Ĭlownfish are native to wide ranges of the warm waters of the Pacific and Indian Oceans. Currently 27 species exist, of which one is in the genus Premnas and the rest are in the subfamilys type genus Amphiprion.
