Clown Anemonefish

The clown anemonefish (Amphiprion ocellatus) is one of the most popular aquarium fishes because it looks like a clown fish, but it’s actually related to the anemonefish family. Clown anemonefish are commonly called “clown anemones,” but there are many different species within the clown anemonefish genus.

The clown anemome fish is often confused with the Orange clownfish (A. perideraion), but the clown anemone fish has a much longer dorsal fin, and the orange clownfish has a shorter dorsal fin.

There are four main types of clown anemonefish:

– Male: The largest type, the breeding male is colored yellowish-green with a dark brown head, while the non-breeding male is colored a reddish-brown with a light green head.

– Female: The smallest type, the female is colored a pale yellow with a blue tail.

– Non-Breeding Male: A large variety of colors, ranging from olive to black, with a yellow belly.

– Breeding Male: Has a similar coloring pattern to the female except for the orange-red body.

Importance to Humans

The clown anemonefish has been used in marine biology research since the 1950s. They are popular because they live in coral reefs and are easy to keep in captivity. Their small size makes it easier to transport them around the world. In addition, the clown anemonefish does not pose a threat to humans and is not considered a food source.

How to Care For Your Clown Anemone Fish

1. Feed your clown anemone fish twice daily. You can feed them flake foods or frozen bloodworms. If you use frozen bloodworms, be sure to thaw them first before feeding.

2. Clean the tank thoroughly after each feeding. Remove any dead tissue or waste that may have accumulated on the bottom of the tank.

3. Change water at least once every two weeks. Make sure to change the water slowly so as not to shock your clown anemonefish.

4. Do not overfeed your clown anemonefishes. Overfeeding will cause their fins to become deformed.

5. Keep your clown anemone fishes away from other animals such as turtles, snakes, and frogs. These animals could harm your clown anemone.

6. Provide plenty of hiding places for your clown anemone, especially during the day when they are active.

7. Place your clown anemone in a well-lit area where it can see clearly.

8. Avoid placing your clown anemone near plants or rocks. This will make it difficult for your clown anemoney to hide.

9. When cleaning your clown anemone’s tank, do not remove more than half of its body. Doing this will cause stress and death.

10. Never place your clown anemone into another tank. It will not survive.


The clown anemonefish (Amphiprion perideraion), known locally as the “sea clown,” is one of many colorful fish found in tropical waters around the world. Clown anemones are often collected for the pet trade. They are popular among aquarists because they are relatively easy to care for, do well in captivity, and produce bright colors.

However, there are concerns about the impact of collecting the fish. Overfishing could cause local populations to decline. Habitat destruction due to pollution and climate change could also threaten the survival of the clown anemones.

Geographical Distribution

The clown anemonefish is named for its distinctive face pattern and clownlike appearance. This species is known to grow up to 1.5 inches long. Clown fish live in coral reefs and are often seen near larger marine life such as sea turtles, octopuses, jellyfish, and schools of small fish. They eat algae and plankton and are considered omnivores.


The clown anemonefish (Amphiprion periderictus) is a non-migrant species that lives in tropical waters associated with rocky or coral reef habitat. Clown anemonefishes live in pairs and typically inhabit areas where there are anemones such as Heteractis magnifca, Stichodactylum giganteum, and Stichodectla mertezi. These fish associate with the anemones because they provide protection and food for both partners. Clown anemonefish are often seen swimming around the tentacles of the anemone. This helps keep the anemone clean and prevents it from getting too large. Clown anemone fishes are known to feed on small invertebrates like crabs, shrimp, and worms. They also eat some algae and detritus.


There is one lateral line along which there are interruptions, and along that line there are 34 to 48 scales. Anemonefish have 10-11 spines on their dorsal fin and 17 rays on their pectoral fin, which distinguish them from other species. There is a round shape to the caudal fin.

In spite of its resemblance to the orange clownfish (Amphiprion percula), the clown anemonefish displays a few distinctive characteristics. Examining the black band that divides the orange color from the white bands on the fish’s body is one of the best ways to distinguish these two species. Unlike the orange clownfish, the clown anemonefish has thick black bands separating the orange and white coloration of its body. The clown anemonefish has thin black bands, sometimes so thin that they may not have any black bands at all. Compared to orange clownfish, clown anemonefish often have a less brilliant color. Furthermore, the clown anemonefish’s head looks plain when viewed from a head-on perspective, while the orange clownfish’s face bulges like a frog’s. The iris color of these two species is also different. Unlike the orange clownfish, the clown anemonefish has a bright orange iris that makes the eyes appear smaller than they actually are; the clown anemonefish has a grayish orange iris.

Orange body with white bands at the head, middle, and tail of the clown anemonefish. As the middle band bulges forward, it is centered on the head. When closely examined, thin black lines appear around the white bands. With black bands on the fin tips, the fish has rounded fins.

In terms of size, age, and growth, the clown anemonefish can grow up to 4.3 inches (11.0 cm) in length. The wild life expectancy of these fish is estimated to be between six and ten years.

Diet : The diet of the clown anemonefish contains various prey items. Foraging for food, this anemonefish consumes algae, copepods, isopods, and zooplankton. The anemonefish consumes the dead tentacles of the anemone as well as any uneaten prey it captures with its stinging tentacles.

Anemonefish have been studied extensively for their general behavior, but not their mating behavior. In the clown anemonefish’s social group, dominance is strictly regulated. Females are always larger than males, while males are smaller than females. Neither of them reproduces through external fertilization within the group. As the hierarchy descends, the size of the non-breeding individuals decreases.

Protandrous hermaphrodites, such as anemonefish, develop into males first, and then possibly into females. Anemonefish may reside in more than one anemone, however if a female is removed or dies, the largest male will become a female. In order to control the formation of other females, females use aggressive dominance to control males.

Mating pairs of this anemonefish are monogamous, and they are territorial with their host anemones. Anemones build their nests on bare rock substrates to protect themselves from predators before they spawn. A male’s courtship behavior includes extending his fins, biting, and chasing a female. Males become aggressive during spawning. The female will make several passes over the nest as the male chases her to the nest when spawning begins. According to the fish’s age, she can lay 100-1,000 eggs, which are orange in color and measure 3-4 mm in length. In the next step, the male fertilizes the eggs by passing them over. Fine adhesive threads hold the fertilized eggs to the bare rock substrate. Any infertile or fungus-damaged eggs are eaten by the male, who fans them with his fins. Males are no longer responsible for their eggs after they hatch. Incubation time is affected by a variety of factors, with cooler temperatures leading to longer incubation times. After a 6-8-day incubation period, the juvenile fish settles on a bottom substrate in search of a host anemone, followed by an 8-12-day larval stage.


The clown anemonefish is a species of fish native to coastal waters around Australia. They are named because of their bright red coloration. Clown anemones are small, colorful fish found throughout the world, including many parts of Asia and Africa. Their common names come from the fact that they look like clown fish.
