Clownfish
Amphiprion ocellaris
Water Parameters
About
The Clownfish is probably the most recognized marine fish in the world, popularized by cinema. Its mutualistic relationship with sea anemones is one of the most fascinating examples of symbiosis in nature. Widely captive-bred, it is the ideal marine fish for beginners.
Behavior & Temperament
Territorial fish that forms stable pairs with a host anemone. The female is dominant and larger than the male. Protandrous hermaphrodite: all are born male and the dominant individual becomes female.
Feeding
Omnivore. Accepts marine flakes, pellets, mysis, brine shrimp, frozen foods and quality pellets. Varied feeding recommended.
Breeding
Egg‑layer with exemplary parental care. Lays eggs on smooth substrate near the anemone. The male tends and aerates the eggs for 7–10 days until they hatch. Breeding is possible in the aquarium.
Care Notes
Prefers a host anemone (Heteractis magnifica, Stichodactyla gigantea), but does well without one. Marine water with salinity 1.023‑1.025. Aquarium with live rock. Choose captive‑bred specimens (hardier and more environmentally responsible).
Compatibility
Peaceful with most marine fish. Territorial only around its host anemone. Compatible with the vast majority of reef fish. Avoid other clownfish in the same tank (except a bonded pair).
