Pink Skunk Clownfish

Some anemonefish species have color variations based on geographic location, sex, and host anemone. A. perideraion, like other members of the skunk complex, does not show any of these variations.

A. perideraion is included in the skunk complex, so has similarities with other species in this complex. The combination of dorsal stripe and head bar distinguishes it from most other species. A. akallopisos, A. sandaracinos, and A. pacificus all lack a white head bar, while A. nigripes lacks the dorsal stripe and has black belly and black pelvic and anal fins. The hybrid A. leucokranos has a broader head bar and the dorsal stripe does not extend the full length of the dorsal ridge.

A. perideraion is found throughout the Malay Archipelago and Melanesia, in the west Pacific Ocean from the Great Barrier Reef and Tonga, north to the Ryukyu Islands of Japan and in the eastern Indian Ocean from Ningaloo Reef, Western Australia, through the Rowley Shoals, Scott and Ashmore Reefs, Cocos and Christmas Islands to Sumatra. It inhabits reef lagoons and outer reef slopes. A. perideraion has been thought to be found at depths of 3–20 m, but surveys using autonomous underwater vehicles of mesophotic reefs at Viper Reef and Hydrographers Passage in the central Great Barrier Reef observed A. perideraion at depths between 50 and 65 m. A. perideraion and A. clarkii are the only anemonefish found on both the east and west coasts of Australia. While the morphological features of A. perideraion are consistent throughout its range, genetic analysis of fish in the Indo-Malay Archipelago has shown a genetic break between the Java Sea population (Karimun Java) and all other locations. A north-to-south connection exists from the Philippines to the rest of the archipelago and a mixing of central populations along the strong current of the Indonesian throughflow.

The relationship between anemonefish and their host sea anemones is not random and instead is highly nested in structure. A. perideraion is a generalist, consistent with its widespread distribution, being hosted by the following four of the 10 host anemones: *Heteractis crispa sebae anemone *Heteractis magnifica magnificent sea anemone (usually) *Macrodactyla doreensis long-tentacle anemone *Stichodactyla gigantea giant carpet anemone Unusually for anemonefish, A. perideraion has been observed sharing a host with other species, including A. clarkii and A. akallopisos.

Anemonefish and their host anemones are found on coral reefs and face similar environmental issues. Like corals, anemones contain intracellular endosymbionts, zooxanthellae, and can suffer from bleaching due to triggers such as increased water temperature or acidification. Local populations and genetic diversity remain vulnerable to high level of exploitation of these species and their host anemones by the global ornamental fish trade. This species was not evaluated in the 2012 release of the IUCN Red List.

It has successfully been bred in an aquarium. In an aquarium, hobbyists have fed the species brine shrimp, mysis shrimp, chopped shellfish, and dried algae.
