Mocha clownfish are characterized by their dark brown coloring with a black-and-white mottling pattern. They can also be found in other colors, including orange and yellow. The average size for the species is about three inches long (although they rarely grow past two inches). At night when the lights go out, these fish become more aggressive and will feed on other fish in the aquarium.

The mocha clownfish is a type of fish that lives in the Indo-Pacific Ocean. Though it can be found near coral reefs, it does not stay close to its territory and ventures into other areas as well.

This species has been observed around Indonesia, Papua New Guinea, Japan, China (Hong Kong), Malaysia, Singapore, and the Philippines.

Origin and description

mocha clownfish

The mocha clownfish has a black body with an orange stripe that extends from the eye to the base of the tail and there are two thick white stripes on each side of its head.

Occasionally, people will see a mocha clownfish with an orange coloration as well as white spots but this is less frequent than brown or black coloring. The natural predators of these species are octopuses, eels, and groupers.

The mocha clownfish are found in the Eastern Pacific from Baja California to Costa Rica. They occur at depths of about 60 feet, which is often among eelgrass patches or algae beds near rocky areas. It’s a semi-aggressive species that feeds primarily on zooplankton, such as jellyfish, shrimp, and squid.

It is most active at dusk when it swims around to find food in the water column or close to the bottom of its habitat. They are known for their bright colors, which serve as a form of camouflage from predators underwater by blending into background features like vegetation and rocks.

A mocha clownfish is a type of fish that can be found near coral reefs. They are brown in color and grow to about three inches long with big, white spots on the body.

The snout has two horizontal black stripes that run across it as well as small, round eyes. This species prefers shallow water so they live on the coral and seagrass of a reef.

The diet of mocha clownfish consists mainly of small invertebrates like shrimp, crabs, tunicates, and urchins as well as other fish that make their way into these habitats. The best time to see this species is during daylight hours, when they feed on algae and other organisms that grow in the daytime.

Scientific Name

The scientific name for this species is Amphiprion ocellaris.

Species profile

The mocha clownfish is also known as the black and white longnose or chocolate-colored anemone fish, with a body that has alternating black bands. This species does not have any distinguishing markings on its face other than occasional patches of brown color. It can grow up to six inches in length and live for about five or six years.

The mocha clownfish is found exclusively in the Indo-Pacific region, and it typically inhabits anemones and sea urchins within coral reefs. The fish can be observed swimming among these invertebrates or moving between them to find a safe space from which they can hunt for food (such as small fish or shrimp).

This species is commonly found in pairs, but sometimes they can be seen alone. They hunt at night and are believed to mate for life. The mocha clownfish only move on land when it needs to find a new anemone home; once one has been selected, the fish will lay eggs within that anemone, and the eggs will hatch in about six days.

Color and appearance

The mocha clownfish is brownish-yellow in color and has spots that are near the head, on the body, and around the anal fin. The dorsal and tail fins are yellow with black stripes which gives it its name.


The mocha clownfish is a small fish, reaching only about two inches in length. It has an oval-shaped body that narrows at the tail and has vertical stripes on its side which are brownish-gray with white and yellow accents. The back of their head is black with red around the eye while the fins are reddish-orange with black spots.

Life cycle

Mocha clownfish, like most other anemones, are born male. Sexually mature males then turn female after a few matings with neighboring females. This process is known as protandry or sequential hermaphroditism and it occurs in many groups of fish that live near sea anemones because the protective tentacles of the anemones provide a safe haven for this type of mating. The female is then able to lay eggs and care for them, while males are better suited to venture out into open water in search of food

Mocha clownfish, like their cousins the Clark’s anemone fish and a few other related species, live in association with sea anemones. Mochas are found only on coral reefs near shorelines where there is plenty of sunlight for the symbiotic algae they feed upon to grow, they can be found at depths as low as 30 feet.

While mochas are not territorial, they will defend their host anemone from other fish that might want to share it with them and the clownfish does this by displaying a white stripe on its body along with a distinctive color pattern. This is easily observed when looking at these little fishes in aquariums.

Are they peaceful or aggressive?

Mocha clownfish are considered to be one of the most peaceful fish in captivity. They pose no threat even to other species like dwarf angels and damsels, unlike some aggressive coral-eating fish.

However, mocha clowns still have a natural instinct for territoriality that can lead them into conflict with others so it is best to keep them in a species-specific tank.

What they eat

Mocha clownfish are omnivores, they eat both plants and animals. The type of food that they eat depends on where their habitat is located. They will feed off of algae and the shallower parts of an ecosystem but go into deeper waters to look for invertebrates like shrimp or crabs to eat as well.

Mocha clownfish tanks mates

Mocha clownfish are aggressive and will not tolerate tank mates. They have been known to nip at the fins of other fish in their tanks, then shoot them away with an erect spine.

Water condition

Mocha clownfish do not require any specific water quality, but they do prefer the temperature to be between 74-82 degrees Fahrenheit.


Mocha clownfish are hardier than many other saltwater aquarium inhabitants and can be bred in captivity. This fish becomes sexually mature at two years old with the male becoming more colorful as he matures. Breeding them is not too difficult either; you simply take one of their eggs and place it inside an urchin or clam. The clam or urchin will then be the mother and you can take out its eggs for further breeding purposes.

You can also use a small cave to help support your mocha clownfish population; this is typically done by removing one female from an aquarium, placing her in a smaller tank with two males, and waiting until the eggs are laid. That way, you have a breeding population without any of the risks associated with introducing new fish in an already established aquarium.


Mocha clownfish live a relatively long time; they can have lifespans of up to eight years.

Parasites and diseases

Clownfish are susceptible to a variety of parasites and diseases, including:


Clownfish are susceptible to predation from many different species of fish that live in saltwater environments or freshwater environments, such as jacks, groupers, and many others.

  • Jacks: There are many different types of fish that can be classified as a jack, and they often feed on smaller or weaker animals that swim by them in the water column.
  • Groupers: Groupers typically live at depths below 50 meters and eat small invertebrates such as shrimp, crabs, squid, etc.
  • Ichthyophthirius multifiliis: Ich can be a deadly parasite to many different types of saltwater fish including the clownfish. Clownfish are susceptible to this type of parasite due to their increased susceptibility to maintaining homeostasis when in a tank.
  • Caryophyllidia: Another parasite that is difficult to control due to the lack of understanding about this type of disease. Caryophyllidia affects clownfish by causing hemolytic anemia, which can lead to many different types of secondary diseases being more prevalent in an infected fish including ichthyopthirius multifiliis.
  • Protozoans: While not as deadly, these are a constant threat to the clownfish population due to their increased likelihood of contracting this type of parasite when they swim through murky water or eat food from the ocean floor.
  • Cryptocaryon irritans: This is one of the most common parasites that affect the clownfish population. It is often found in marine environments and can be contracted by swimming through the water or eating food off of a surface that has been contaminated with this parasite
  • Amyloodinium ocellatum: This type of parasite enters the fish’s body through their gills, eyes, mouth, skin lesions, etc., and can be contracted from the environment.

Does it make good pets?

Mocha clownfish, like most other types of clownfish, do not make good pets. They are sensitive to the ammonia and nitrate levels in their environment so they require a high level of care that is difficult for a person with little experience working with fish. In addition, mocha clownfish eat live food such as brine shrimp and other small animals, which are not easy to care for.

Signs of a healthy fish

  • Clear eyes without any cloudiness or redness
  • Bright colors without bleeding into white spots
  • The color should be uniform, not bleeding into one another.
  • The color is solid and doesn’t have any cloudy areas from parasites or scrapes on the fish’s body.
  • There are no signs of red around their fins where they are injured
  •  Clear scales with firmness to them, this is a good indication of a healthy fish.
  • The scales should not be peeling or have any other signs of damage that would suggest the fish’s immune system is compromised
  • No overgrowth on any part of their body. This indicates good health and nutrition. If there is an overgrowth, it may mean your water quality needs to be improved.

Signs to watch out for:

  • The presence of white spots on the fish’s body is a sign that they have parasites and should be treated as soon as possible. These can lead to more serious health problems if not checked by an expert.
  • If you notice your tank has green algae growing up from the bottom, this is a sign that your tank needs more oxygen and sunlight.
  • If there are any scratches or popped bubbles on the fish’s skin, it means they have been fighting with other fish in their home environment. This could become dangerous if left unattended for too long.
