Cinnamon Clownfish- Everything about keeping one

The juvenile ‘’Cinnamon Clownfish”, appears to have been soaked in spices. This specie has a variety of common-names that reflect its enigmatic look.  Other names for this species include Black-Backed anemonefish, Melanopus Anemonefish, Fire Clownfish, Dusky Anemonefish, Black Anemonefish and Red and Black Anemonefish. Their scientific-name means Black-foot referring to their dark-ventral-fins; same as Maldives Anemonefish. 

Cinnamon Clownfish are resilient fish that thrive in both fish-only tanks and coral reef settings. As a result, these fish are an excellent option for both newbie and experienced fish-keepers. If you put red and black anemonefish into the tank simultaneously, clownfish could be housed with a variety of clownfish. They have really distinctive look in comparison to other clownfish. Dusky Anemonefish could live a life longer than normal when you captivate them with care. These fish are active, delightful, and keep your attention by following you if you go through from their aquarium. Keep reading to know “the peculiarities, how to care, how to breed and everything about the Cinnamon clownfish” below:

Background: ‘Bleeker’ explained the False Percula clownfish in ‘1852’.

Scientific Name: Amphiprion melanopus

Family: Pomacentridae

Habitat/Range: These are native of in the Pacific Ocean, New Guinea, Queensland Australia, in Indonesia from Bali then eastward to the southern part of the Philippines, Solomon Islands, New Britain, Fiji, Vanuatu, Tonga, Marshall Islands, New Caledonia, Kiribati, Caroline Islands, Society Islands, Samoa Islands, and the Marianas.

cinnamon clownfish Appearance: 

The fins around the anas and pelvis, as well as the body, will be a pale reddish-brown or red mixed black. Most juveniles would have red/dull reddish-brown colours with black on all the fins. The black shade on their body is changeable. There could have been a faint covering on the top of their-bodies, or the black that might run horizontally around the white stripe to the anal-fin region. 

Certain colour variants don’t have black saddles on their bodies.The Coral Sea, the Society Islands, Fiji, and Tonga all have these fish. They have only one wide-stripe that runs at the back of their eyes. It might be blue/white in colour. The caudal fin is yellow in color, while the lateral and posterior fins are reddish-orange. They’ll seem to have a white/blue headband. Adults have three stripes and are a burned orange hue all throughout, though 2 of them might fade as these fish grow older.

cinnamon clownfish Size: 

Blackback anemonefish have a size approx. 3-4.7 inches (7.6-11.99 cm). The clownfish that reach five inches in size; is the aggressive one, because they become hostile with growing age.

cinnamon clownfish Color: 

If we talk about the color, it’s reddish-orange with varying shades of black. There is only one blue-white band and posterior fins are black in color.  Both genders have a lot of black on their backs and flanks.

Similarity with other clownfish: In the past, clown fish were characterized in the field by morphological-aspects like as colour-pattern, whereas in the laboratory, additional traits include scales on the head, tooth-form, and body-ratios were used. The above characteristics were used to divide species into six complexes. 

Because cinnamon clownfish is a part of the tomato-complex, it is comparable to other species of this group. The look of Australian clownfish and Blackback clownfish is indistinguishable, but they are regionally different, with Australian clownfish restricted to northwestern-Australia. Barberi clownfish was initially assumed to be a geographical variant of cinnamon clownfish, but there are substantial colour pattern variations, with red and black anemonefish having a dark-brown/blackish body contrasted to Barberi clownfish’s bright-orange. In the upper opercular line, Melanopus anemonefish possesses 19 to 26 spines, but Barberi has just 11 to 19.

Difference between male and female cinnamon clownfish 

Cinnamon clownfish born as unbiased for gender. They turn to male or female after the juvenile stage and after that, they can’t be changed back. In both genders, females are larger in size, aggressive, and the dominant one. They become a shield for their home (whether it is a clay pot, a nesting site, an anemone, and the entire fish tank) if they feel any danger. After the death of a female, the dominant male turns to female, and the succeeding male is ready for mating. Females have a creamy to the white face and are 0.4 to 0.8 inches (1 to 2 cm) bigger than males.


17 years – They could live about seventeen years in wildlife and in captivity, they could live around 3 to 5 years usually but with good care, they could live even more. They are resilient, long-lived clownfish that can survive for up to 17 years.

Behavior and Temperament:

Semi-aggressive. They live as commensals with sea anemones and also with some large-polyp-stony corals.

Care level: 


Conservation Status:

Cinnamon clownfish are not at the risk of extinction. Though, coral reefs have been declining from the past generation (fifteen to thirty percent), according to the ADW. It is because of the fisher-men who catch clownfish for selling them as pets. National Geographic announced for the first time, the rise in the sales of clownfish up to three times. These are not included in the IUCN Red List.


Tank Set up for Cinnamon Clownfish 

Tank size: 

30 gallons (114 L) for a single melanopus anemonefish, up to 40 gallons for a pair, and with a sea-anemone and other coral-reef, it should be up to 55 gallons.

Suitable for Nano Tank: 


Occasionally – A nano-tank is suitable only as juveniles.

Tank Setup: 

The tank is filled with marine rocks or corals and they look beautiful but the reason is that blackback clownfish are compatible with corals.

Tank Lightening:

 There should be appropriate lighting for the tank-setup. As we know, clownfish live with sea-anemones and for them, there should be gradual increasing and decreasing light systems. If you have sea-anemones, you’ll need intense light. Fish-only aquariums, on the other hand, don’t need bright lighting.

Live Rock Requirement: If you don’t have a sea-anemone for your clownfish, it’s necessary to have rock-structures with sufficient hiding-places.

Substrate Type: Any

Maintenance of the tank: 

Daily: Do check the water-filter, water-temperature, specific-gravity, and all the other equipment placed in the tank.

Weekly: Do check water-quality one time a week necessarily.

Monthly: Change up to ten to twenty-five percent as per the total-volume of water every 2-4 weeks/when required. Gradual placement of new mates in the tank is also significant.

  • Equipments and Tank setting 

They are relatively easy to handle and resilient. When provided a well-maintained aquarium and enough water parameters, they thrive. Even if these fish can tolerate low water-quality, any saltwater fish that is exposed to it for a longer period of time will develop diseases. Routine water changes would also help to replace the trace-elements that coral reefs and fish require. Water change techniques for tanks of varying types and sizes are described here.

Cinnamon clownfish could be housed in a saltwater tank or a small reef tank. These types of larger and more lively clownfish required a minimum aquarium size of 30 gals. Provide a little bigger aquarium, up to 40 gals, while having a couple, especially if you are going to introduce other fish. Melanopus clownfish is courageous and could swim to the top to eat once adapted to its home-aquarium.

This species is found in coastal locations, where the temperature is usually around Eighty degrees Fahrenheit (26.7 degrees Celsius). The temperatures of water in a tank should be from 74° and 79° F (23° and 26° C). Extremes of temperature exceeding 90° F (32° C) or below 64° F (18° C) would be too much for them. Temperatures of 79°F to 83°F (26°C to 28°C) are ideal for spawning. 

The tank must have a suitable architecture that gives both visual enjoyment and technical shelter from the water movement. It may be accomplished with rocks, live rocks, or artificial reef inserts. If there isn’t a sea-anemone nearby, Dusky anemonefish aren’t choosy. They’ve been seen alongside soft corals, mushroom corals, Large Polyp Stony Corals (LPS), and even Acropora corals as temporary shelter. When there are no coral reefs, these would hang-out with a power-head. A saltwater tank with corals and plenty of rocks would provide them enough places to hide.

The ideal architecture includes a mix of exposed swimming-areas and hidden hiding-spots. These may be placed in sediment-free tanks for the convenience of cleaning, but certain tank-mates might require a substrate, thus it would be essential to arrange occupants ahead of time.

Black-Backed Clownfish Water Parameters

Water Movement: 

Water-movement should be saunter for the purpose of feeding.

Water Changes: 

Water should be changed two times a week – Do the water changes of fifteen percent every two weeks or thirty percent a month. In the presence of corals in the aquarium, it should be five percent weekly to fifteen percent every two weeks, based on the size of the tank.

These are; I could say ideal parameters as per my knowledge, false clownfish could accept little variations and less-than-perfect conditions. We are still responsible for meeting the cultivation requirements but it’s convenient for those who are concerned about keeping cinnamon clownfish as pets or for leisure activity. 

Brackish: No

Cost: 15$-20$

Compatibility: Community safe

Aquarium Hardiness: Very hardy

Prone to Disease: No


Cinnamon clownfish is recommended for beginners since it’s easy-to-care for and reasonably tough. This is especially true that they are bred in an aquarium because these are quite resistant to many of the lethal illnesses and viruses. The members of Amphiprion are normally tough, and if, become sick, these fish might be cured comfortably using copper medications or pharmaceuticals. 

Melanopus anemonefish captured in the wild probably take longer to adjust to their new environment. Because these fish aren’t as tough as humans, providing them with live meals and filtered clean water aids them to acclimate. Before you are going to buy these fish, keep an eye on them for a week/so in the merchant’s tank to make sure they’re adjusting.

Inquire when these fish have to be fed, and keep an eye out for things like proper feed and attentiveness. This is also the greatest time to carefully check the fish because they’re not in a closed environment and any concerns with their health can be seen more easily. Avoiding the fish that are lethargic or uninterested, as well as timid-eating with a little-appetite. Buying wild-caught fish directly from a distributor could also be effective.

A Dip in freshwater with formalin and malachite green shortly after you bring them home can help avoid common infections, but it isn’t necessary if they come from a reputable supplier, you believe in the purity of the aquarium, and cleanliness. With an anemone, your options for tank-mates expand owing to the added protection the sea anemone provides to clownfish.

Dusky Anemonefish Feeding Guide 


Frozen food, flaked food, and live foods


Both plants and animals (omnivore), and if you don’t have algae in the tank use products with Spirulina. In Wildlife they mostly eat anemone parasites, copepods, zooplankton, and algae. But at the zoo, they feed on chopped fish, mysis and brine, Formula I & II, small crustaceans, Flake, worms, vitamin gelatin, and Pellets.

Pellet/Tablet: Yes

Flake Food: Yes

Live foods (shrimp, worm, or fish): 

Variety of live-food in their diet – while not required, it may help condition them for spawning. Live diets will improve live specimens and pre-breeding conditioning.

Vegetable Food: ½ of their diet

Meaty Food: ½ of their diet

Feeding Frequency: 

Feed the adults two times a day and juveniles three to four times a day. They are of average-metabolic system and ought to be fed two times a day. But if you have a pair of black-backed anemonefish and they are in the breeding phase, raise the feed 3 times/day.

Dusky Anemonefish tank mates

Compatible Fish: 

Cinnamon clownfish coexist with a diverse variety of marine-community-fish. These will protect their sea-anemone against intruders, however, most of them are not really attracted towards a face-full of stinging-tentacles in the first place. This clownfish can sometimes be kept-together, increasing the probability of a mated-pair form. 

These fish are 2nd to Maroon-Clownfish in terms of hostility, and shouldn’t be kept alongside other clown fish. Other calm fish, while also small clownfish, would be attacked. It’s recommended to keep them alone or in a verified male or female couple. Though they tolerate young clown fish of the same species, adults would chase and assault any mature clownfish that is not a male or female couple. Only if the aquarium is quite huge, make sure not to place them with damsels.


Clownfish are noted for their “singing,” which consists of chirps and pops made with their teeth and amplified with their jaws! There are roughly 29 kinds of clownfish. When they are attacked or attacked, they deploy a variety of combinations. Clark’s Clownfish, Tomato Clownfish, and Pink Skunk Clownfish are the three loudest.

The differences in behavior among clown fish of similar species are fascinating and easy to spot. A female’s persistent dominance prohibits a male from switching gender. A leading clown fish would exhibit an “antagonistic attitude,” whereas the submissive fish would exhibit “appeaser-behaviour.” 

The subservient one reacts to the hostile fish’s particular-actions:

  • Whether the belligerent fish, usually a female, is following and tweeting, the submissive clownfish, that might be a male/a sub adult, would quickly shake their body and make clicking noises when they glide upward. The aggressive clown fish’s jaw snapping causes the subordinate clownfish to shake their body or head.
  • The violent clown fish’s jaw snapping causes the submissive fish to shake their head/body.
  • The hostile clownfish’s lean ventral causes the submissive clownfish to tremble.
  • When a violent clown fish exhibits pectoral leaning, the subservient clown fish exhibits ventral-leaning.

  • Sharks/Rays
  • Wrasse-fish only

Only keep one type of clown in your tank. Mixing clown species is not a good idea.

Symbiotic Relationship with Sea-anemones: 

The symbiotic relationship between an anemone and a clownfish is a classic example of two organisms benefiting each other; the anemone provides protection and shelter for the clownfish, while the clownfish provides nutrients in the form of waste while also scaring away potential predator fish.

These fish are fit-in a coral-reef setting, particularly when paired with an anemone. Cinnamon clownfish rarely harm corals, apart from picking-algae from the root of a coral-reef they’ve taken up as hosts. They will have a wonderful realistic atmosphere, thanks to a host sea-anemone. Although most fish limit the anemone’s stinging tentacles for fear of becoming a meal, your clownfish would spend a lot of its time inside it. Sea anemones are a beautiful-addition to any reef-tank, but these are more difficult to maintain. Once you make a decision to retain a sea-anemone, ensure its unique requirements are addressed.

Only two types of sea-anemones are compatible with Dusky anemonefish:

  • Bubble Tip Anemone/Rose Anemone (Entacmaea quadricolor)
  • Magnificent Anemone/Ritteri Sea Anemone (Heteractis magnifica)
  • Leather Sea Anemone (Heteractis crispa)

In the natural habitat, the cinnamon clownfish is only being seen with the Rose Anemones (Entacmaea quadricolor). Sea-anemones are indeed a beautiful-addition to any coral-reef tank, as they’re more difficult to maintain. They will not travel far from their host if maintained with a sea-anemone, but they are considered to be hostile and would swim-out to scare away  other fish.

Blackback clownfish are not associated with anemones mentioned below:

  • Condylactis gigantea, Giant Golden Anemone 

Condy Anemones (Condylactis gigantea) should be added with caution. They are Predator-anemones with high mobility. These are not “clown-hosting-anemones.”  The sting of condy anemones is far greater than that of clownfish-hosting-anemones, and any clownfish dumb-enough to confront it risks being their prey. 

Reef Compatible: 

These clownfish do good in reef aquariums. Anemones are perfectly acceptable when living with the clownfish, in a coral reef system. Melanous anemonefish rarely harm corals, apart from taking algae from the base of a coral reef they’ve taken up as a host. Clownfish will have a rich realistic atmosphere and it’s because of the host-anemone. Whereas most fish keep them away from the anemone’s stinging-tentacles for fear of becoming their meal, clownfish may spend long hours inside it. Sea-anemones are a wonderful-addition to any coral reef tank, but they’re more difficult to maintain. If you want to retain a sea-anemone, ensure that its unique requirements are addressed.

  • Mushroom Anemones – Corallimorphs
  • Feather Dusters
  • LPS corals
  • SPS corals
  • COLT corals
  • Rasta Corals – Sinularia spp.
  • Brain Corals – Trachyphyllia Radiata
  • Gorgonians, Sea Fans
  • Leather Corals
  • Hammer Corals
  • Toadstool Corals
  • Soft Corals (xenias, tree corals)
  • Star Polyps/Organ Pipe Coral
  • Zoanthids – Button Polyps, Sea Mats
  • Sponges, Tunicates

Predator Tank Compatible: No

Number to a tank: 

You can keep them alone or in pairs, but it’s best if you just place one pair at a time. Because they may get aggressive if there are more couples.

How to Breed Cinnamon Clownfish?

Step 1: 

More than a pair of melanopus clowns could be maintained in your aquarium. Keep in mind, however, that only one of them will live as a breeding couple. The female is the larger of the two individuals, while the male is the smaller of the two. The other individuals will survive as immature-males. When appropriate, breeding will occur on its own; all you have to do is provide them with a clean, caring, and safe environment. 

Step 2:

If you want to hurry things up, make sure they’re getting a nutritionally-balanced and calorie-balanced diet. Most appropriately you should have to make sure to provide them a calorie and nutrients balanced food many times a day. Live-foods are typically more healthful than canned-foods.

Step 3:

Red and black anemonefish are amongst the easiest clownfish to reproduce because they’ve been selectively bred. They are the simpler types of clownfish to grow thru larval development, despite the low hatch-rates. These could have been “rabbits” among the salt water majority.

Step 4:

These are born unbiased by birth, although cinnamon clownfish are genders converters. They transform into immature males in response to particular social signals, and once the time arrives, a dominant-fish will transform into a female. These clownfish, on the other hand, have their own unique twist. Dusky anemonefish have been observed to stray farther out of their host-anemone than others.


It is extremely difficult to pair clownfish, and if a female refuses to accept a potential male, the relationship will end with that male’s death. It’s sufficient to nurture a group of juveniles and let them pair up on their own. It is better to segregate the pairing-couple from the rest of the tank. It is possible that you will maintain both the female and male in the same aquarium and they will not tolerate each other. For that male, it becomes dangerous.

After the matching has been completed, it is a terrific idea to nourish the couple with plenty of high-quality, fresh food. It’s even easier because you don’t need a sea-anemone to spawn. These fish are substrate-breeders and prefer to lay their eggs in a solid surface or cave, such as an upturned clay pot.

Pre-spawning Behavior: 

Males in the natural habitat have been observed to evict smaller males and claim the female just before sub-adult seems to have an opportunity to switch sexes. This clown fish exhibit courtship including tilting-away from each-other with their ventral-surfaces closer and leaning to each-other with their dorsal-surfaces closer, according to the couple. In doing so, these might shake their heads/one/both of them might rise up. Clownfish don’t reproduce for the rest of their lives, and they will stop reproducing some years earlier they die.

Spawning Process: 

Once the water temp reaches 79° F, cinnamon clownfish will start breeding. The male begins to bite at the substrate with increasing frequency and intensity a few days before spawning in order to attract the female. During this period, the female’s tummy grows with eggs, and she may or may not join him in the substrate biting.

Once the couple has chosen a spawning place, they will clean it well to ensure proper egg adhesion. The area is usually near to the anemone, which protects its tentacles by its presence. If the eggs are near the tentacles just before spawning, the clownfish pair will pick at the anemone to cause it to withdraw, exposing the entire spawning spot. The female puts her belly against the surface, quivers, and drags herself slowly down the surface, leaving a trail of crimson eggs behind her, and will do so in a circular pattern until all of her eggs have been laid. After that, the male will approach her and fertilise the eggs.

The eggs will hatch 1 to 1.5 hours after sunset in 8 to 10 days, depending on water temperature. They metamorphose into post-larval fish on the eighth day after hatching. Then they begin to resemble miniature copies of their parents. belly against the surface, quivers, and drags herself slowly down the surface, leaving a trail of crimson eggs behind her, and will do so in a circular pattern until all of her eggs have been laid. After that, the male will approach her and fertilise the eggs.

Protection of their eggs: 

Spawning takes place two to three hours after the sun sets for the day and lasts about one and half hours, with a clutch of eggs ranging from (172 to 339) eggs on average, with an average of two hundred and forty-nine eggs depending on the size of the female. The bright red eggs are fanned and mouthed to keep them clear of fungal infections and debris while they develop, as well as to keep them well oxygenated.

Hatching: The eggs will hatch one to one and half hours after sunset in eight to ten days, depending on water temperature. They transform into post-larval fish on the eighth day after hatching. Then they begin to resemble miniature copies of their parents. Despite 2 of 3 mid-body bands fade with aging. In terms of larvae-survival, these clowns are amongst the best, though not the simple and easy, clownfish to reproduce in captivity.

Ease of Breeding: Moderate


It’s a good idea to acclimate a  dusky anemonefish in a deep bucket so that they don’t tumble out. Take the following steps:

  • Fill a large bucket halfway with water and place your clownfish inside
  • Drizzle-acclimate for 45 minutes at a rate of three drips per second. During this time, your fish adjusts to the tank’s water parameters.
  • When the fish has completed the acclimatisation process, gently place it in the tank with the help of a fish-net.
  • Keep in mind that you don’t have to fill the tank with water from your fish’s home.

How do you keep Blackback Anemonefish with care?

Cinnamon Clown are super strong and easy to keep. As a first attempt in the saltwater hobby, beginner aquarists will find success with the Black-backed anemonefish. Regardless of how “bulletproof” they are, poor water quality will still cause illness and disease. Your anemonefish will have a long life if you do normal water changes, give them a variety of foods, and keep them in the right tank with the right tank mates.

In nature, these clownfish associate with anemones, but in the tank, they are perfectly content without one. These clowns are just as content to take shelter amid the rockwork. If you’re going to try an anemone, wait at least 6 months before adding this clownfish to develop experience evaluating and adding calcium, magnesium, and other nutrients to your tank. They will adore their Bubble Tip Anemone, but if there are any other tankmates around, they will get violent.

Cinnamon clown is hardy and quite easy to look for. When given good water conditions and a well-maintained tank, they thrive. Despite their tolerance for less-than-ideal water quality, any saltwater fish exposed to it for an extended period of time will succumb to illness and disease. Regular bi-weekly water changes will also aid in the replacement of trace elements lost by the fish and corals.

  • What could you do to keep your Clownfish away from getting sick?

When given good water conditions and a well-maintained tank, they thrive. Despite their tolerance for less-than-ideal water quality, any saltwater fish exposed to it for an extended period of time will succumb to illness and disease. Regular bi-weekly water changes will also aid in the replacement of trace elements lost by the fish and corals.

Be careful if you notice the following symptoms:

  • Anorexia 
  • Strenuous breathing
  • White-spots on the body
  • Open-sores
  • Bulging eyes
  • Cloudy-eyes
  • Reddish fins 
  • Frayed and ripped fins

Anorexia is frequently the first indicator. If your Clownfish refuses to eat something, explore the signs of other ailments earlier to start treatment. The other indicators are self-evident and will reveal whether dusky anemonefish get sick. Diseases can be introduced to your tank via live rock, corals, and fish that have not been adequately cleaned or quarantined. The easiest way to avoid this is to make sure that whatever you want to add to the tank is thoroughly cleaned or quarantined. Other measures to prevent sickness include providing high-quality diets, clean, high-quality water, and appropriate tank mates.

Somewhat than subjecting the fish to the arduous work of being exposed to medication and distress, it is preferable to keep an eye on the symptoms.

  • Diseases

These fish are often fairly tough; therefore, the disease is rarely an issue in a well-kept tank. But, if they do become ill, though, some conditions can be fatal. Clownfish are subject to similar diseases and conditions that other saltwater fish are, such as fungal, bacterial, parasitic, and other disorders. When excellent water purity is not ensured, the temperature varies excessively, or the fish is agitated resulting from poor tank-mates, all marine fish would become unwell. A disturbed fish seems to be more vulnerable to illness.

Be careful if you noticed the following Disease:

  • Brooklynellosis, often known as Clownfish-Disease/Brooklynella hostilis (Brook)
  • Marine Ich/Cryptocaryon irritans/Velvet Disease/White Spot Disease Crypt
  • Uronema (Uronema marinum)
  • Oodinium ocellatum (Synonyms: Amyloodinium ocellatum, Branchiophilus maris)

These are mostly parasitic infections.

  • Treatments

Crypt (saltwater Ich) is the easiest to treat, but they’re all manageable if found early enough. Marine Velvet is a parasitic skin flagellate that is one of the most clown problems in marine aquariums. It is a fast-moving pathogen that attacks the gills principally. Brook kills in 30 hours, but Uronema is one of the fastest killers, killing in as little as 24 hours. Uronema is commonly contracted when an aquarist reduces salinity to treat another ailment but does not go far enough. This parasite grows in brackish water with a specific gravity of 1.013 to 1.020, which is ideal for it. If you have an ailment, make sure to cure it at a regular salinity of approximately 1.023 or a lower salinity of around 1.009. 

For both salinity-ranges, Rapid Treatment and other thirty-seven percent Formaldehyde solution preparations will perform properly, however, the lesser 1.009 will aid with the oxygen concentration. As the salt level decreases, the proportion of oxygen in the water increases. “I discovered that when I used the right hyposalinity of 1.009, no greater when fighting Brook or Crypt, my clownfish seemed to breathe better and would be less worried”… Carrie McBirney.

Diseases can be introduced to your tank via live rock, corals, and fish that have not been adequately cleaned or quarantined. The easiest way to avoid this is to make sure that whatever you want to add to the tank is thoroughly cleaned or quarantined. Other measures to prevent sickness include providing high-quality diets, clean, high-quality water, and appropriate tank mates.


What are the common names of cinnamon clownfish?

These clowns are also known as Black-Backed anemonefish, Melanopus Anemonefish, Fire Clownfish, Dusky Anemonefish, Black Anemonefish and Red and Black Anemonefish.

What is the difference between males and females of cinnamon clownfish?

Females have a creamy to the white face and are 0.4 to 0.8 inches (1 to 2 cm) bigger than males.

Name some diseases common in cinnamon clownfish?

Brooklynellosis, often known as Clownfish-Disease/Brooklynella hostilis (Brook), Marine Ich/Cryptocaryon irritans/Velvet Disease/White Spot Disease Crypt, Uronema (Uronema marinum), Oodinium ocellatum (Synonyms: Amyloodinium ocellatum, Branchiophilus maris) are prevalent in most clownfish.

How many eggs black-backed clownfish reproduce?

They produce 172 to 339 eggs usually, with an average of two hundred and forty-nine eggs depending on the size of the female.


Finally, we can say that keeping cinnamon clownfish at home is an easy struggle for novices. The aquarium setup, water parameters, and equipment are all simple to keep clean and maintain. It is imperative that you educate yourself first, as feeding the Black-backed Clown is not an easy task. If you don’t know how much and how many times, they should be fed, it will cause health issues for your dusky anemonefish. The choice of tank-mates should be done wisely thus, your melanopus anemonefish will not become prey of any other fish or turn out to be aggressive to destroy the tank’s environment. Red and Black Anemonefish can live as long as they can in captivity if they are properly cared for.
