Amphiprion chagosensis és una espècie de peix de la família dels pomacèntrids i de l'ordre dels perciformes.
Der Chagos-Anemonenfisch (Amphiprion chagosensis) kommt nur an der Küste des Chagos-Archipels in Wassertiefen von 10 bis 25 Metern vor. Als Lebensraum bevorzugt er die Außenriffe, weniger Lagunen oder das Riffdach. Die Art wurde anhand von Exemplaren beschrieben, die bei Diego Garcia gefangen wurden. Es ist unbekannt mit welcher Seeanemone er in Symbiose lebt.
Der Chagos-Anemonenfisch wird acht bis zehn Zentimeter lang. Die Länge beträgt das 1,8- bis 1,9fache der Körperhöhe. Er ist bräunlich-orange gefärbt. Ein weißer Querstreifen zieht sich direkt hinter dem Auge über den Kopf, ein weiterer, schmalerer zieht sich von der Einbuchtung zwischen dem stacheltragenden und dem weichstrahligen Teil der Rückenflosse bis vor die Afterflosse. Die Bauchflossen sind schwärzlich, die Schwanzflosse ist transparent.
Die Rückenflosse hat zehn bis elf Hart- und 15 bis 17 Weichstrahlen, die Afterflosse zwei Hart- und 13 bis 14 Weichstrahlen. Die Brustflossen werden von 18 bis 20 Flossenstrahlen gestützt. Auf dem ersten Kiemenbogen befinden sich 17 bis 20 Kiemenreusenfortsätze. Die Seitenlinie wird von 36 bis 43 Schuppen begleitet.

Amphiprion chagosensis, the Chagos anemonefish, is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes. It is named for the Chagos Archipelago in the Indian Ocean and it is endemic to the archipelago. The original specimens were collected at Diego Garcia Atoll, Chagos Archipelago.[2]
Clownfish or anemonefish are fishes that, in the wild, form symbiotic mutualisms with sea anemones and are unaffected by the stinging tentacles of the host anemone, see Amphiprioninae § Symbiosis and mutualism. The sea anemone protects the clownfish from predators, as well as providing food through the scraps left from the anemone's meals and occasional dead anemone tentacles. In return, the clownfish defends the anemone from its predators, and parasites.[3] Clownfish are small-sized, 10–18 centimetres (3.9–7.1 in), and depending on species, they are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. Within species, there may be color variations, most commonly according to distribution, but also based on sex, age and host anemone. Clownfish are found in warmer waters of the Indian and Pacific oceans and the Red Sea in sheltered reefs or in shallow lagoons.
In a group of clownfish, there is a strict dominance hierarchy. The largest and most aggressive fish is female and is found at the top. Only two clownfish, a male and a female, in a group reproduce through external fertilization. Clownfish are sequential hermaphrodites, meaning that they develop into males first, and when they mature, they become females.
Adults are light brown with two white bars with dark edging encircling the body. All fins are dusky brown.[2] They have 10-11 dorsal spines, 2 anal spines, 15-17 dorsal soft rays and 13-14 anal soft rays.[4] They reach a maximum length of 10 cm (4 in).[2]
None known.
The Chagos anemonefish is mainly distinguished by location, with similar species mostly having a geographic separation, with A. akindynos being found on the Great Barrier Reef and Coral Sea and A. allardi in East Africa. A. bicinctus is found in the Red Sea but has an overlapping distribution at Chagos. A. chagosensis has a narrower headbar and a whiteish caudal fin. Specimens can also be distinguished by differences in predorsal scalation.[2]

A. chagosensis, with Stichodactyla mertensii, Mertens' carpet sea anemone Amphiprion chagosensis, the Chagos anemonefish, is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes.

Conhecido como peixe palhaço de Chagos ou peixe anêmona de Chagos (Amphiprion chagosensis), é uma espécie de peixe palhaço que pertence á família Pomacentridae e á subfamília Amphiprioninae. Foi nomeado chagosensis pois a espécie é endêmica do Arquipélago de Chagos, no Oceano Índico,[1] mas há relados de serem encontrados no Território Britânico do Oceano Índico, mas não tem certeza se a espécie possa ser encontrada nessa localidade.[2] Os primeiros exemplares desta espécie foram coletados no Atol Diego Garcia, que faz parte do arquipélago.[3]
Os adultos são castanhos alaranjados claros com duas listras brancas com orlas escuras circundando o corpo. Todas as barbatanas são castanhas escuras.[3] Podem atingir o comprimento máximo de 10 cm.[3] Não se conhece nenhuma outra variação de coloração, apenas castanho alaranjado claro.
Assim como os outros peixes palhaço, vivem associados á anêmonas, eles fazem um tipo de simbiose em que as anêmonas o protegem de predadores, além de fornecer alimento, deixando os restos de comida. Em troca, o peixe palhaço defende a anêmona de predadores e parasitas.[4]
Cada peixe palhaço possui tipos diferentes de anêmonas especificas para fazer simbiose. O peixe palhaço de Chagos, pode fazer simbiose com anêmonas bolha (Entacmaea quadricolor), anêmona magnifica (Heteractis magnifica), Macrodactyla doreensis e a anêmona carpete de Mertens (Stichodactyla mertensii).[5]
