Two-banded Anemonefish Care Guide
Amphiprion bicinctus is a Red Sea and western Indian Ocean anemonefish that pairs with several host anemone species and reaches about 14 cm.

Overview
Amphiprion bicinctus is a marine anemonefish of the family Pomacentridae, distributed across the Red Sea and the western Indian Ocean. Its body ranges from yellow-orange to dark brown and carries two white bars edged in black, with the head bar notably wider than the second; juveniles show three bars before losing the rear one. The species is a generalist that associates with several host anemones.
Taxonomy
- Family: Pomacentridae
- Genus: Amphiprion
- Scientific name: Amphiprion bicinctus
- Common name: Two-banded anemonefish, Red Sea clownfish
Habitat
The species occupies sheltered reefs and shallow lagoons of the Red Sea, the western Indian Ocean, Socotra and the Chagos Archipelago. FishBase records it as a non-migratory, reef-associated fish at depths of about 1-30 m in tropical waters. It hosts in at least five anemone species, including Entacmaea quadricolor, Heteractis aurora, Heteractis crispa, Heteractis magnifica and Stichodactyla gigantea, with a documented preference for Entacmaea quadricolor.
Tank requirements
- Minimum tank volume: 100 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 (females larger than males)
- Lifespan: 12-14 years
Reef compatibility
Amphiprion bicinctus is considered reef-safe and does not harm corals or invertebrates. A bubble-tip anemone (Entacmaea quadricolor) is the most readily accepted host but is not required for long-term captive care.
Diet
In the wild it is an omnivore that feeds on algae and zooplankton. In aquaria it accepts a varied diet of marine pellets, frozen mysis and enriched brine shrimp, fed roughly twice daily.
Compatibility
The fish is semi-aggressive and territorial around its host. It mixes well with tangs, royal gramma, wrasses and cleaner shrimp, but other clownfish species and aggressive triggerfish should be avoided. Only a single bonded pair should be kept per anemone.
Breeding
Like all anemonefish, the species is a protandrous sequential hermaphrodite: individuals mature first as males, and the dominant fish becomes female. Only one breeding pair reproduces per group. Spawning is oviparous; the demersal eggs adhere to substrate near the anemone and are guarded and aerated by the male. FishBase notes that functional sex reversal can complete within 26-145 days after removal of the female.
Conservation status
IUCN Red List: Least Concern, assessed in 2010.
Two-banded Anemonefish Breeding Guide
Overview
Amphiprion bicinctus is found in the western Indian Ocean, the Red Sea, Socotra and the Chagos archipelago. Males reach about 10 cm and females about 14 cm. It uses several host anemones, including the bubble-tip anemone Entacmaea quadricolor, Heteractis aurora, Heteractis crispa, the magnificent sea anemone Heteractis magnifica and the giant carpet anemone Stichodactyla gigantea, with research indicating a preference for Entacmaea quadricolor over Heteractis crispa.
Sexing
It is a sequential hermaphrodite: individuals develop into males first and become females when they mature, and only two fish per group reproduce through external fertilization. Sex follows social rank, so raising juveniles together and allowing the largest to mature into the female is the standard route to a breeding pair.
Conditioning
A bonded pair held in a stable, warm reef and fed frequently on a varied diet comes into breeding condition. A host anemone such as Entacmaea quadricolor is readily accepted but is not strictly required for spawning in captivity.
Breeding Setup
Species-level egg and larval data are not documented, so breeding follows the general anemonefish pattern. The breeding setup provides a flat, defensible spawning surface such as rock within the pair's territory near any host anemone present.
Spawning Behavior & Trigger
As an anemonefish it is a demersal substrate spawner: the pair deposits adhesive eggs on the prepared flat surface near its territory and fertilizes them externally. A settled pair under stable reef parameters and frequent feeding spawns in repeated cycles.
Egg & Fry Care
Following the anemonefish pattern, the male tends the nest, fanning and cleaning the eggs until they hatch. Larvae are pelagic and are reared in captivity on small live foods, starting with rotifers and moving to Artemia nauplii as the larvae grow.
Common Challenges
Because species-specific egg, incubation and larval figures are not documented, breeders rely on the general anemonefish behavior. As with all clownfish, the planktonic larval phase is the bottleneck, demanding a continuous supply of correctly sized live food and stable, high-quality water.
