Black to entirely orange with pair of pale white or blueish bars, second bar is wider, tail is white or yellow, usually with abrupt boundary if the body is dark, other fins can be anything from yellow to orange-black.


Unevaluated by the IUCN Red list, but it is one of the most common and widespread of anemonefishes.


Indo-West Pacific. Persian Gulf to Micronesia, New Caledonia and Fiji, SouthWest Japan tot North Australia. On lagoons and reefs or reef slopes down to 55 meters.


Oviparous, with elliptical eggs. Monogamous and distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs. In social groups of anemonefish there is only 1 female and 1 or more males. The female is always largest and dominant, and she chooses just 1 male to mate with. Any offspring they have is undifferentiated until the time they turn into males. If the female dies, the male that is highest in hierarchy will turn into a female, choose a new mate, thus creating a new mating couple. All remaining males will go up one rank in the hierarchy.


Up to 15cm.
