Amphiprion chagosensis
Family: Pomacentridae ยท Clownfish
Also known as: Chagos Anemonefish, Chagos Islands Clownfish
The Chagos Clownfish is one of the rarest and most geographically restricted clownfish species, found exclusively in the remote Chagos Archipelago in the central Indian Ocean. It displays an orange to brownish-orange body with two white bars, one behind the eye and another mid-body, creating a pattern similar to its close relative the Clark's Clownfish. Its limited range and the protected status of the Chagos Marine Reserve make it an exceptionally rare find in the aquarium hobby.
In its natural habitat, the Chagos Clownfish associates with bubble-tip anemones (Entacmaea quadricolor) and magnificent sea anemones (Heteractis magnifica) on the reefs surrounding the Chagos Islands. It lives in small groups with a dominant female, a breeding male, and several smaller subordinate males following the typical clownfish social hierarchy. The species' isolation has led to subtle but distinct genetic and morphological differences from its Indian Ocean relatives.
On the rare occasions this species becomes available to aquarists, it proves to be a hardy and adaptable fish similar in care requirements to other small Amphiprion species. It is beginner-friendly, reef-safe, and peaceful by clownfish standards. Its extreme rarity and unique geographic origin make it a highly coveted species among dedicated clownfish collectors and marine fish enthusiasts.
Chagos Clownfish are omnivores that feed on algae, zooplankton, and small invertebrates in the wild. In captivity, they accept marine pellets, flake food, frozen mysis shrimp, brine shrimp, and enriched preparations. Feed two to three times daily in small portions.
The Chagos Clownfish is one of the more peaceful clownfish species and is compatible with most community reef fish. It should not be housed with other clownfish species to avoid hybridization and aggression. Territorial around its host anemone but generally non-threatening to tankmates.
Check CompatibilityChagos Clownfish are protandrous hermaphrodites and can be bred in captivity following standard clownfish protocols. Due to their extreme rarity, captive breeding is highly encouraged to reduce pressure on wild populations. Eggs are laid on flat surfaces and hatch in 7-10 days.
