Clownfish
Scientific name: Amphiprion ocellaris
Shallow reef inhabitant that lives among the stinging tentacles of host anemones.
Quick facts
- Approximate size8–11 cm
- Average weight15–30 g
- Life expectancy6–10 years (captivity)
- ActivityDiurnal
Basic information
- Habitat: shallow coral reefs in warm waters of the Indo-Pacific.
- Diet: zooplankton, small invertebrates, and food scraps; in aquariums accepts prepared marine food.
- Sexual dimorphism: all are born male; the dominant individual transforms into a female in each group.
- Predators: larger fish and other reef predators; the anemone offers protection against many of them.
Life in the wild
How this species lives in its natural environment, with the waters, shelters and resources it needs.
Species overview
The clownfish is an icon of tropical reefs and marine aquaristics.
Natural habitat
It lives in reefs with good lighting, clear waters, and moderate water movement around host anemones.
Behavior
It stays close to its anemone, making small movements to feed and defend territory.
Special features
It has a special mucus layer that allows it to tolerate the stings of its host anemone.
Conservation and threats
Reef degradation and excessive trade have affected some populations, although captive breeding helps compensate.
Curiosities
Striking details about this species that help better understand its biology and role in aquatic ecosystems.
- Its symbiotic relationship with anemones is a classic of nature documentaries.
- It has become world-famous thanks to animated films.
- In aquaristics it is bred relatively easily in captivity, reducing pressure on wild populations.
- It can live in pairs or in small groups organized by hierarchy.
Welfare profile
Summary of the most critical points if this species is kept in aquariums, ponds or specialized facilities.
Space and facilitiesHigh
In captivity it needs well-cycled and stable marine aquariums, with adequate marine parameters.
Water quality and parametersHigh
The presence of a suitable host anemone improves its natural behavior, although it increases system requirements.
Handling and stressMedium
It is sensitive to pollutants and sudden changes in salinity or temperature.
Clownfish in captivity
General information aimed at professional facilities, public aquariums and educational projects. It does not intend to promote capture or impulsive keeping of aquatic fauna.
⚠️ Before keeping fish like this species, it is essential to review local regulations, ensure adequate facilities and minimize impact on wild populations.
Suitable facilities
Recommended for marine facilities that already have experience maintaining reef systems.
Feeding in responsible centers
The diet includes varied marine food: frozen, live, and quality pellets.
Handling and welfare
It is important that specimens come from captive breeding whenever possible.
Ethical message
In environmental education, the clownfish is used to talk about symbiosis, reefs, and climate change.
Many aquatic species suffer from massive captures, uncontrolled trade and irresponsible releases. The priority should always be to protect rivers, lakes and seas, reduce pollution and consume seafood responsibly.
