Tomato Clownfish – A Complete Guide

This popular and well-known fish ‘Tomato Clownfish’ has the rich hue of a ripe tomato, as the name suggests and other names as Blackback Anemonefish, Red Clownfish, Bridled Anemonefish, Fire Clown, Tomato Anemonefish, Red tomato clown, and Onebar Anemonefish. The Tomato Clownfish is one of five anemonefish that make up the “Tomato Complex.”

They are easy to breed in a home aquarium. The female will be the greater of the two, and the two fish will often stay together in the aquarium. Tomato clowns are typically darker in colour than their wild cousins, but as the fish grows older, it will brighten to a lovely red/orange hue. Three white bands and black pectoral fins distinguish juveniles, which go away as the fish matures. Keep reading to acquire more knowledge about “their peculiar behavior, their tank maintenance, how to breed, and everything else about the Tomato Clownfish.”

Background: Brevoort described for the first time ‘Red Tomato Clown’ in 1856.

Scientific Name: Amphiprion frenatus

Family: Pomacentridae

Habitat/Range: Indo-Pacific to Oceania – also present in Japan, Australia, Southeast Asia, and Indo-Malaysian Borneo, Taiwan, Sumatra, Thailand, Vietnam, southern Japan, the Philippines, and lagoon reefs in the South China Sea are all home to red clowns.

Appearance:

The adult fish has a distinctive black outline with a white head bar or vertical stripe just behind the eyes, that is joined over the head. On the sides, females are often blackish. Males are smaller and have a reddish coloration. Juveniles have two or three white bars or are a darker red. 

Here, one thing is you should have to know is that the Blackback anemonefish is frequently misinterpreted among two of its Tomato Complex siblings. This species has been found to interbreed for both the Red Saddleback and the Cinnamon Clownfish resulting in some intriguing colour variations! They do have a minute black on their mid-body, which is the feature of mature fish or large-females, although they could be mistaken with Cinnamon Clownfish.

Size

The length of Red Tomato Clown is around 3-5.5 inches (7.6-14 cm). Females are larger than males. 

Color

The intense red colour of the Tomato clownfish, which ranges from burnt orange to tomato red, is named after it. On its head, right behind the eyes, it has a white vertical stripe. Color distinguishes juveniles from adults.

Difference between males and females

Tomato Clownfish are sequential hermaphrodites, which means they first develop into males and then mature into females. Clownfish are born male but have the ability to carry both female and male reproductive organs. As a result of their capacity to change sex, the dominant male does not need to venture into dangerous waters in search of a partner. 

Lifespan

17 years– These tomato anemonefish are tough and long-lived, with a lifespan of seventeen years or more. They go black with age.

Diet

Tomato clownfish eat small shrimp, planktonic fish eggs, and crustacean larvae are one of the planktonic copepods, benthic crustaceans, and filamentous algae.

Behavior and Temperament

They are semi-aggressive. However, as they grow older, they can become territorial and violent. It can be calm, but it will become aggressive if some other fish enters its area.

Care level

Easy to Moderate.

Conversation Status

There is no danger of extinction of this specie. The population-trend is a question. In the western Pacific Ocean, it is fairly common. Red clownfish are frequently overused in the tank trade, and their natural environment is in places where dynamite-fishing is used. The blackback anemonefish’s host sea-anemone could be subject to bleaching-episodes, opening them up to predators.

TANK OR AQUARIUM CONDITIONS

Tank Set up for Tomato Clownfish

Tank size: 30 gallons (114 L) – For a single specimen, a minimum of 30 gallons is required, with a pair requiring 40 gallons or more. If you want to keep it with an anemone, you’ll need a tank that’s at least 55 gallons.

Suitable for Nano Tank: No

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

Tank Lightening: Until you have an anemone, lightening isn’t a problem. If you’re trying to house it with a sea-anemone, it’ll be difficult. Anemone requires an intense lightening system. 

Live Rock Requirement: Yes, this is for hiding areas. When there are no anemones around, rock-structures with sufficient hiding-spaces are essential.

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

Clownfish could be housed in a salt water tank or a small coral-reef aquarium. Because the female bridled clownfish can grow to be as larger as 5.5 inches (14 cm), at least an aquarium capacity of thirty gallons (one hundred and fourteen liters) is required for a single organism. It’s recommended that a couple should be kept with other fish in at least of Forty gallons water.

If your aquarium doesn’t have a sea-anemone, make sure there are enough hiding spots. However, an anemone is preferred, it’s not required if they may easily adjust to a salt water aquarium without each other. These fish frequently replace a coral reef/other invertebrates/maybe a rock-structure.  Allow fire clowns to feed in a place where water is run slowly. The temperature of water in aquariums should be among 72°-82° F (22° to 27° C). High temperature exceeding 90° F (32° C) or under 64° F (18° C) might be too much for them. 

Red tomato clown doesn’t require extra lightening; however, a sea-anemone would demand a lot of it. Later mentioned, also requires adequate quality of the water and a well-maintained aquarium, which is six months to a year old. Tomato clowns would swim at all depths, however, when a host is available, they would spend most of the time inside/near it, and would be hostile against tank mates.

Water Movement: This has to be slow when you are feeding the clowns.

Water Region: They could be present at all levels of water in the tank. These fish prefer to stay their long term whether they do have a host sea-anemone or corals, but they’ll still wander from the sea-anemone to pursue other tank mates.

Water Hardness: 18 dGH

As per my knowledge, these are ideal parameters; though, fire clowns could endure minor discrepancies and less-than-ideal situations.

Cost: $15-$20

Red Tomato Clown Anemonefish Feeding Guide

Feed: Frozen food, flaked food, and live foods

Diet: These fish eat both plants and animals (omnivores). In the absence of algae, you have to use items that include Spirulina.

Flake Food: Yes

Pellet/Tablet: Yes

Live foods (shrimp, fish, or worms): Including a variety of live foods in their diet is not needed, but it may assist them to prepare for spawning. Pre-breeding training and live specimens will benefit from live meals. You could give them extremely small feeders-shrimp with a lot of nutrients in their guts.

Vegetable Food: 1/2 of their diet

Meaty Food: 1/2 of their diet

Feeding Frequency: Adults should be fed twice a day, and youngsters should be fed three to four times a day. They have a normal metabolic system and should be fed twice a day. If you have a pair of Tomato Clownfish in the reproductive stage, increase the feed three times every day.

Bridled Clownfish tank mates

Compatible Other Fish:

It could be difficult to find red tomato clownfish that get along in the same aquarium. Though tomato clownfish haven’t the hostile temperament, they might have problems if housed in an aquarium with some other species of clownfish or larger fish.

Fire Clown in the wild likely assumes a sea-anemone as their home and seldom moves up to some centimeters from it for the rest of their life. These fish in the house tank might behave similarly, getting highly possessive, particularly around certain clownfish. If you would like to house other fish in the same aquarium with your clownfish, keep in mind you have quite room.

Overpopulation could be harmful to your clownfish since it raises their anxiety levels, forming them more vulnerable to tank fish diseases and affecting the aquatic environment in the aquarium. It might be possible to maintain smaller, peaceful varieties alongside your clown fish when you have adequate room. To avoid difficulties, keep in mind that they are settled prior to putting any additional fish, and afterward put the extra fish one at a time.

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 behaviour 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 clicks noises when they glide upward. The aggressive clown fish’s jaw snapping causes the subordinate clownfish to shake their body or head.
• The violent clownfish’s jaw snapping causes the submissive fish to shake their head/body.
• The hostile clownfish lean ventral causes the submissive clownfish to tremble.
• When a violent clown fish exhibits pectoral leaning, the subservient clown fish exhibits ventral-leaning.

A list of compatible tank mates for Tomato Clown are given below:

Peaceful fish: (But need to monitor, when place in a mini-tank) 

• Gobies
• Dartfish
• Assessors 
• Fairy wrasses

Semi-Aggressive: (But need to monitor and don’t place with any-other clown)

• Anthias 
• Clownfish 
• Dwarf angels

Aggressive: (But need to monitor and place in a big aquarium)

• Dottybacks 
• 6-Line & 8-Line 
• Wrasse Damselfish

Large Semi-Aggressive: 

• Tangs 
• Large Angels

Shrimps, Crabs, Snails: (But need to monitor because Red Tamato Clown might eat them)

Safe:

• Starfish
• Feather Dusters
• Bristle Worms
• Flatworms
• Clams, Scallops 
• Oysters
• Copepods
• Amphipods 
• Mini Brittle Stars

Non-compatible tank mates

These could be the worst tank-mates with tomato clownfish:

Large Aggressive (Predatory):

• Lionfish 
• Groupers

• 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. Tomato 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 Tomato Clownfish:

• Bubble Tip Anemone/Rose Anemone (Entacmaea quadricolor)
• Pizza or Carpet Anemone (Cryptodendrum adhaesivum)
• Leather Sea Anemone (Heteractis crispa)

In the natural habitat, the bridled 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 live with the clownfish, in a coral reef system. Red Tomato clowns 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.

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 Tomato Clownfish?

More than a pair of fire 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. 

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 do that make sure to provide them a calorie and nutrients balanced food many times a day. Live-foods are typically more healthful than canned-foods.

Spawning: 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: Bridled Anemonefish have been observed drifting further away from their host anemone than other clownfish. Males in the wild are infamous for abandoning their mates, kicking out a lesser male in a nearby anemone, and capturing his female, who then repeats the process with the next smaller fish.

Depending on the couple, clownfish acts during romancing include angling away from each other with their abdomen surfaces close together, angling towards each other with their dorsal surfaces close together, thrashing their heads, or one or both participating in head standing. Clownfish do not breed for the whole of their lives and will stop breeding several years before they reach the end of their life expectancy.

Spawning Process: Once the water temp will reach up to 79° F, Fire 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 (309 to 551) eggs on average, with an average of four hundred and forty 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.

Methods To Start Breeding: There are many methods so that red clowns may start breeding. The 3 basic techniques to start-up breeding them, and we’ll go over it according to how much energy you have to spend and how much budget you’ve prepared to invest.

• The Cheapest Clownfish Breeding Method
• The Quickest Tomato Clownfish Breeding Method 
• The Perfect Middle Ground Between the Two

The Cheapest Clownfish Breeding Method: Using this fish’s gender-changing powers is the most cost-effective method. Purchase approximately 6 youngsters and maintain them together.

They’ll create a pecking-order as they get older, and you’ll quit with a mated female and male who would produce eggs. Buying 6 juveniles of all but the most exotic types of clownfish is less expensive than purchasing an adult pair. That’s also the method that those that have never raised fish before should use.

The Quickest Tomato Clownfish Breeding Method: That’s the strategy to use if you don’t want to wait for so long. Please remember that the expense is the trade off there. Purchase a mated couple from a trustworthy breeder. That’s a female and male who had previously paired effectively. This could cost anything from only 100$ for the basic variations to several 100$ for the more decorated ones, based on the particular type.

The Perfect Middle Ground Between the Two: A ‘best of both worlds’ technique could be the right option if you wouldn’t want the degree of confusion connected with the 1st method and the expense involved with the 2nd technique. Buy a pair of subadults and one is large than of two as the most essential factor. Both of them could be males, or the smaller ones.

Ease of Breeding: Moderate

Acclimatization

It’s a good idea to acclimate a Fire Clown 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?

Fire Clown is super strong and easy to keep. As a first attempt in the saltwater hobby, beginner aquarists will find success with the Tomato Clownfish. 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.

Red tomato 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 away your Clownfish 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 tomato clownfish 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 (salt water 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 tomato 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 will decreases, the proportion of oxygen in the water increases. “I discovered that when I used the right hypersalinity of 1.009, no greater when fighting Brook or Crypt, my clownfish seemed to breath 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.

Conclusion

Overall, we can declare that keeping tomato clownfish at home is an easy effort for beginners. The tank set up, water parameters, and equipment is all simple to keep clean and maintain. It is imperative that you educate yourself first, as feeding the Fire Clown is not an easy chore. Your common tomato clownfish will suffer health problems if you don’t know how much and how often they should be fed. Tankmates should be chosen carefully so that your red tomato clown does not become a victim of other fish or grow aggressive enough to harm the tank’s environment. Bridled Anemonefish can live as long as they can in captivity if they are properly cared for.
