Amphiprion polymnus (Saddleback anemonefish)


Various amounts of black to dark brown and yellow to orange, snout is usually light yellow, 2 wide white bars and a white edging on the dorsal fin.


Unevaluated by the IUCN Red list, but a less common anemonefish due to the limited species of anemone it lives on.


Asian pacific, Indonesia and Northern Australia to the Solomon Islands, North to Southwest Japan. It lives predominantly on Haddon’s anmones in a depth range of 2-35 meters.


Monogamous and a protandrous hermaphrodite. Oviparous, 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 12 cm.
