Amphiprion ocellaris, commonly known as the Ocellaris Clownfish or False Percula Clownfish, is a species of anemonefish found in the Indo-Pacific. It is renowned for its symbiotic relationship with sea anemones, providing protection to the anemone from predators and receiving shelter from its stinging tentacles. This species is highly popular in the aquarium trade due to its vibrant coloration and relatively peaceful demeanor.
Caratteristiche fisiche
- Forma del corpo
- compressed
- Colorazione
- Bright orange body with three distinct, vertical white bands. The anterior band is located just behind the eye, the middle band is centrally located on the body, and the posterior band is on the caudal peduncle. Each white band is typically outlined in thin black. The fins are generally orange, often with black margins.

Consigli per l'identificazione
White Bands
Count the number of white vertical bands. A. ocellaris consistently has three bands. The black outline around these bands is a key differentiator from A. percula.
Dorsal Fin Spines
Observe the number of dorsal fin spines. A. ocellaris typically has 10-11 dorsal spines, whereas A. percula usually has 9-10.
Eye Color
The iris of A. ocellaris is typically orange, matching the body color, while A. percula often has a darker, sometimes black, iris.
Size
A. ocellaris tends to be slightly larger than A. percula, though this can be difficult to ascertain without direct comparison.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- 1-15 meters (3-49 feet), typically in shallow, protected reef areas.
- Ambiente
- Coral reefs, lagoons, and sheltered inshore waters. Always found in association with host sea anemones.
- Areale geografico
- Eastern Indian Ocean and Western Pacific Ocean, including the Andaman Sea, Thailand, Malaysia, Indonesia, Philippines, New Guinea, and northern Australia (Northern Territory and Queensland).
Informazioni sull'acquario
- Livello di cura: beginner
- Temperamento: peaceful
- Dieta: omnivore
- Dimensione minima della vasca: 30 gallons
- Temperatura: 75-82°F (24-28°C)
- Livello di pH: 8.1-8.4
- Durezza: 8-12 dKH
- Compatibilità: Generally compatible with most peaceful reef-safe fish. Can be kept in pairs or small groups if introduced simultaneously to a sufficiently large tank with multiple anemones or host alternatives. May become territorial towards other clownfish species.
- Requisiti speciali: Requires a host anemone (e.g., Entacmaea quadricolor, Heteractis magnifica, Stichodactyla gigantea) or a suitable substitute (e.g., certain corals like Euphyllia spp.) for optimal well-being, though they can survive without one. A well-established aquarium with stable water parameters is crucial. Provide varied diet including high-quality flake food, pellets, and frozen foods like mysis shrimp and brine shrimp.

Fatti chiave
Protandrous Hermaphroditesbehavior
Amphiprion ocellaris are protandrous hermaphrodites, meaning all individuals are born male and can later change to female. In a group, the largest and most dominant individual becomes the female, and the second largest becomes the breeding male. If the female dies, the breeding male changes sex to female, and the next largest male in the hierarchy takes his place.
Symbiotic Relationshipinteresting
The Ocellaris Clownfish forms an obligate symbiotic relationship with certain species of sea anemones. The clownfish is immune to the anemone's stinging nematocysts due to a protective mucus layer on its skin, allowing it to live safely within the anemone's tentacles. In return, the clownfish defends the anemone from predators and may help clean it.
Finding Nemo Starfunny
The animated character 'Nemo' from the Disney/Pixar film 'Finding Nemo' is an Ocellaris Clownfish, which significantly boosted the species' popularity in the aquarium trade.
Territorial Defensebehavior
Despite their small size, Ocellaris Clownfish are highly territorial, especially when guarding their host anemone and eggs. They will aggressively chase away much larger fish that venture too close.
Diet in the Wildbehavior
In their natural habitat, Ocellaris Clownfish are omnivores, feeding on zooplankton, copepods, algae, and sometimes small invertebrates found within or near their host anemone.
Informazioni di sicurezza
Sicuro- Livello di sicurezza: safe
- Velenoso: No
- Commestibilità: not recommended
- Note sul maneggio: Generally safe to handle, though like all fish, direct contact should be minimized to prevent stress to the fish and potential transfer of skin oils or bacteria. They do not possess venomous spines. Their host anemones, however, are stinging organisms and should be handled with care.
Specie simili
Percula Clownfish
Amphiprion percula
A. percula typically has 9-10 dorsal spines (vs. 10-11 for A. ocellaris), a thicker black outline around its white bands, and often a darker, sometimes black, iris. The overall body color of A. percula can be a more intense orange or even reddish-orange, and its white bands are often wider and less regular than those of A. ocellaris.
Clark's Anemonefish
Amphiprion clarkii
A. clarkii has a much more variable coloration, often dark brown to black with yellow or orange fins, and typically only two white bands (one behind the eye and one on the caudal peduncle), though sometimes a third faint band can be present. It is generally larger and more robust than A. ocellaris.
