The orange-fin anemonefish (Amphiprion chrysopterus) is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes, found in the Western Pacific north of the Great Barrier Reef from the surface to 20 m, to include the Pacific Ocean between Queensland, Australia, and New Guinea to the Marshall and Tuamotus Islands.

[3] Clownfish are small-sized, 10–18 cm (3.9–7.1 in), and depending on species, they are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches.

Within species, color variations may occur, most commonly according to distribution, but also based on sex, age, and host anemone.

Clownfish are found in warmer waters of the Indian and Pacific Oceans and the Red Sea in sheltered reefs or in shallow lagoons.

They feed on mainly on planktonic copepods, algae, echiuroid and sipunculoid worms, and pelagic tunicates.

Generally yellow in the body edges, it is yellow-brown to dark brown in the middle sides, with two white vertical stripes, the first behind the eye and the second before the anus.
