''Amphiprion tricinctus'', also known as the three-band anemonefish, is a species of anemonefish that is endemic to the Marshall Islands in the western part of the Pacific Ocean. Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone. It is a sequential hermaphrodite with a strict sized based dominance hierarchy: the female is largest, the breeding male is second largest, and the male non-breeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male will change to female if the sole breeding female dies, with the largest non-breeder becomes the breeding male. The fish's natural diet includes zooplankton. ==Description==
The body of ''A. tricinctus'' is yellow-orange at the snout, belly, pelvic and anal fins tending to dark brown or black at the tail. As the common name suggests, as an adult it has 3 white bands or bars. They can grow to be about long
