The red clownfish, also known as Amphiprion bicinctus, is one of the most popular varieties of aquarium fish. They are medium-sized, with a bright red body and white stripes on their head. While they can live in an unheated aquarium for some time, they prefer to live in warmer water because this species is found primarily off the coast of Australia and Indonesia where the water is warm.

The red pigment they have comes from symbiotic algae called zooxanthellae that live within their body. These fish also form colonies consisting of one female and many males where they all work together to protect the territory.

In a red clownfish’s natural habitat, it is often found in the bottom of crevices or caves. When they feel threatened, red clownfish will defend themselves by biting their attacker with venomous teeth. They have evolved to avoid being eaten by predators by living amongst sponges and other organisms that are poisonous to humans.

Amphiprion bicinctus is a red, orange, and yellow fish that are found in the oceans of Australia. They tend to live on coral reefs or rocky surfaces where they feed mostly on zooxanthellae and plankton (pretty much anything).

These bright redfish can grow up to 14 cm long and live up to 20 years.

Amphiprion bicinctus can be found in the Pacific and Indian oceans as well as off of Australia, New Guinea, Indonesia, Solomon Islands, Palau, and many other places around Asia including Japan and Korea.

The Amphiprion bicinctus is a species of anemonefish in the family Pomacentridae. The red clownfish has been found living within and without sea anemones as well as burrowing into soft substrates like sand or coral rubble to form their homes. It can be difficult to identify them in their natural habitat because they resemble the yellow and black striped blennies.

The red clownfish is a small-sized fish that can grow to be about 35 millimeters long (including its tail fin). They are typically red or orange with white stripes. They have a dark spot on each shoulder, which is either red or black and also have a white tip on the tail fin.

They are found living within anemones all over the Indo-Pacific region from Japan to Australia and north to New Guinea. They can be seen in shallow reef habitats near coral reefs as well as lagoons with soft sand substrates. They also burrow into the sand to form a home.

The red clownfish is not just limited to living within anemones, it can live without them as well. This species of fish has been seen both in and outside of sea anemone habitats throughout their range from Japan all the way up past New Guinea. Without proper research, it can be difficult to identify them due to their similarity in coloration and markings with the yellow and black striped blennies.

Species profile

red clownfish

Amphiprion bicinctus or red anemone fish are a type of reef-associated marine species. They can be found in the Indo-Pacific region, from the Indian Ocean to Southern Japan and Eastern Australia. This red coloration comes from symbiotic algae that live on the red clownfish’s skin and give it its red hue. The red anemonefish is a solitary species, living near reefs in shallow water (usually between five to twenty meters deep).

This type of anemonefishes feeds mainly on various types of filamentous algae which they scrape from rocks or corals using their teeth.

They are considered a vulnerable species because red anemonefish populations in the wild have been declining due to overfishing. In some cases, their natural habitat has also been threatened by pollution and climate change.

Color and appearance

The red clownfish owes its red coloration to symbiotic algae that live on the fish’s skin. The red anemonefish is a solitary species, living near reefs in shallow water (usually between five to twenty meters deep).

They are vulnerable because red anemonefish populations in the wild have been declining due to overfishing. In some cases, their natural habitat has also been threatened by pollution and climate change.


The red clownfish is a relatively small fish, reaching a maximum size of about five inches. They have red stripes and black spots on their body, with white bars along the upper side of their tail fin. Juvenile red clownfish are more brown-red in color than adults.

Life cycle

The red clownfish is a type of fish in the Amphiprion genu. They are born male but may become female when a dominant partner dies. They are ovoviviparous and the males guard the eggs against predators such as triggers (triggers eat their own weight in fish every day).

When an egg hatches, it becomes part of the plankton for about two weeks before it swims up to the surface and becomes a baby red clownfish.

Are they peaceful or aggressive?

Some red clownfish may be aggressive, but mostly they live peacefully. They are generally reef-dwellers and can coexist with other fish in the same tank as long as there is plenty of territory for each to stake their claim on. If a red clownfish is challenged or territorial issues arise, then any nearby red clownfish will come to their aid.

They are social creatures that like to group together and live with others of the same species because they feel more comfortable in a community.

Red clownfish care information

What they eat

The red clownfish is omnivorous and eats a variety of foods. They have been observed eating algae, seaweed, plankton, copepods, zooplankton (including larval shrimp), crabs, starfishes, and other invertebrates. There have also been many reports that they will feed on red algae.

Tank mates

Red clownfish are usually found in pairs or groups. They can also be kept with larger fish such as lionfish, other red clownfish, and blue damsels.

They need at least a 55-gallon tank to live comfortably. The water should have salt added to it that mimics their natural habitat of coral reefs off the coast of Australia.

Water condition

The red clownfish thrives in water with a pH range of about eight to nine. They are sensitive to nitrate levels and should not be housed with any other species that needs high levels, such as discus or sharks. It can handle salt but does best at one-quarter the salinity level found in natural seawater.

The red clownfish does best in a tank with lots of coral, live rock, and other shelters to choose from since they are active swimmers who like having plenty of places to hide. They can be aggressive so it’s important not to house them with any species that might look tasty or have similar coloration when swimming quickly.

Breeding red clownfish

Breeding red clownfish is not a difficult ordeal, but it does require some planning because they are an egg-laying species. They need to be provided with clean water and live rock that has been cured of any parasites before the female will lay eggs in them after mating. It’s also important for their environment to have plenty of hiding places in the form of corals and other shelters.

Females can lay up to 200 eggs at a time, but it’s more likely they will only produce about forty or fifty eggs over several weeks. The red clownfish is not a fast-growing species, so you may have quite some time before your offspring are sexually mature enough to breed.


The red clownfish has a lifespan of about ten years in the wild.

Parasites and diseases

Clownfish are often subject to disease and parasites, which is why they should be kept in a clean aquarium with plenty of live rock. They can also suffer from an eye infection called “popeye”, which makes the eyes bulge outwards due to fluid buildup behind the lens. They should not eat for at least a few days and the infected water should be cleaned.

Maintaining red clownfish is important for their health, but they may not live as long in captivity because they have less of an immune system to fight off disease.


Most red clownfish are prey to larger fish and marine mammals, such as dolphins. If they survive past the first few months of life, these predators become less frequent in their diet. One study found that 52% of red clownfish will be eaten by a predator during their lifetime.

Does it make good pets?

Yes. Red clownfish make great pets for experienced marine aquarium owners. They do not require as much care and are not aggressive, making them a good pet choice for people who have less than perfect experience with fish keeping.

To keep red clownfish healthy, they need to be fed at least twice per day while in captivity. Some can grow to be more than 12 inches long, which may not fit in many people’s aquariums.

Experts recommend red clownfish to experienced fishkeepers because they can live up to 15 years and require less care than other types of marine life.
