Amphiprion perideraion (Pink anemonefish)

Identification

Pinkish to orange color, with a narrow white head bar and a white dorsal stripe starting between the eyes and running to the tail, bright eyes.

Status

Unevaluated by the IUCN Red list, but a fairly common species in the Asian Pacific.

Habitat

Asian Pacific. From Indonesia to the Marshall Islands, Micronesia, Southwest Japan to Asutralia and New Caledonia. It lives on 4 different species of anemone (Heteractis magnifica, Heteractis crispa, Macrodactyla doreensis and Stichodactyla gigantea), in sheltered reefs from 3-20 meters.

Reproduction

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.

Size

Up to 10cm.

Prey / Predation

They feed on macro-algae, diatoms, tunicates, copepods and benthic worms

Special features

In Bali (Indonesia) they occur together with the closely related Indian Ocean species Amphiprion akallopison and have even been found sharing the same anemone.
