Seychelles Anemonefish Care Guide

Amphiprion fuscocaudatus is a Seychelles and Aldabra anemonefish with three white bars, an orange snout and a distinctively striped dark tail.

Compiled by Aquairi from published sources · Published · Updated

Overview

Amphiprion fuscocaudatus is a marine anemonefish of the family Pomacentridae found only in the Seychelles and at Aldabra in the western Indian Ocean. The body is dark brown to blackish with three white bars and an orange or yellow snout, breast and belly. The dark tail carries longitudinal streaks separated by lighter sections, which distinguishes it from the closely similar Amphiprion chrysogaster. The species is almost never available in the trade.

Taxonomy

  • Family: Pomacentridae
  • Genus: Amphiprion
  • Scientific name: Amphiprion fuscocaudatus
  • Common name: Seychelles anemonefish

Habitat

The species is restricted to the Seychelles and Aldabra. FishBase records it from lagoon and seaward reefs, particularly patch reefs, at depths of about 5-30 m in tropical waters near 3-10 °S. It associates with the Mertens' carpet anemone, Stichodactyla mertensii.

Tank requirements

  • Minimum tank volume: 150 L
  • Temperature: 24-26 °C (75-79 °F)
  • pH: 8.1-8.4
  • Carbonate hardness (dKH): 8-12
  • Specific gravity: 1.024-1.026
  • Maximum size: about 14 cm
  • Lifespan: 13-14 years

Reef compatibility

Amphiprion fuscocaudatus is reef-safe and does not damage corals or invertebrates. A carpet anemone host is appreciated but not essential in captivity.

Diet

It is an omnivore that feeds on zooplankton and algae in the wild. In aquaria it accepts marine pellets, frozen mysis and enriched brine shrimp, fed about twice daily.

Compatibility

The fish is semi-aggressive and territorial near its host. Tangs, royal gramma, wrasses and cleaner shrimp are suitable companions, while other clownfish species and aggressive triggerfish should be avoided. Keep one bonded pair per anemone.

Breeding

Like other anemonefish, the species is oviparous with distinct pairing during breeding. The demersal eggs adhere to substrate and are guarded and aerated by the male.

Conservation status

IUCN Red List: Least Concern, assessed in 2010.

Seychelles Anemonefish Breeding Guide

Overview

Amphiprion fuscocaudatus, the Seychelles anemonefish, is found only in the Seychelles Islands and Aldabra in the western Indian Ocean and reaches a maximum length of about 14 cm. It associates with the host anemone Stichodactyla mertensii. The species is almost never seen in the aquarium trade and lacks published captive-breeding data; the account below applies the well-documented reproductive pattern of the genus Amphiprion, of which it is a member.

Sexing

As a clownfish, A. fuscocaudatus is a protandrous sequential hermaphrodite. Individuals develop first as males, and the dominant fish becomes female. Groups follow a strict size-based dominance hierarchy with the female largest and the breeding male second; only the dominant pair reproduces. Functional sex therefore tracks social rank and relative size rather than external markings.

Conditioning

A pair is formed by allowing a dominance hierarchy to develop among juveniles or by pairing a large and a small fish. Conditioning depends on stable reef water and regular feeding, since clownfish are omnivores. The natural host Stichodactyla mertensii reflects wild conditions but is not strictly required for spawning in an aquarium.

Breeding Setup

  • Established male/female pair (largest fish becomes female)
  • Mature reef aquarium with stable salinity and temperature 24-26 C
  • A flat rock or hard surface near shelter for egg deposition
  • pH 8.1-8.4, strong biological filtration

Spawning Behavior & Trigger

Reproduction in Amphiprion is linked to the lunar cycle and often occurs around the full moon. The male courts the female by chasing and nibbling her and erecting his fins. The female cleans a rock near shelter and lays a clutch of up to about a thousand conical eggs around 3-4 mm long that adhere to the substrate, after which the male fertilises them externally.

Egg & Fry Care

The male provides parental care, cleaning, guarding and fanning the eggs with his pectoral fins. Incubation lasts about six to seven days, with the orange eggs darkening as the embryos develop. The hatched larvae enter a pelagic stage of up to roughly twelve days before settling and seeking a host anemone.

Common Challenges

The pelagic larval phase is the main difficulty: the tiny larvae need rotifers then enriched Artemia in a dedicated low-flow larval tank with strict water-quality control. The extreme rarity of A. fuscocaudatus in the hobby limits access to unrelated breeders, and the lack of species-specific data means husbandry is extrapolated from related clownfish.
