Crowntail Betta Species Profile & Care Guide: 2024 Updated |

Crowntail Bettas are a relatively new variety of Betta that has gained popularity since it was introduced in the United States in the early 1990s. They’re known for their “sunburst” or “strawberry” tail, and they come in several colors, from blue to orange, red, violet, and white.

In this article, we will discuss the Crowntail Betta and all of its features. This is an excellent fish for any aquarist, with various colors to choose from and qualities that make it a good community tank-mate.

The Crowntail Betta (Betta splendens) is a gourami species native to Southeast Asia, including Cambodia, Laos, Malaysia, Thailand, and Vietnam.

The Betta is most known for its brilliant colors, which are most beautiful when seen up close. Since the Betta was once considered part of the royal family, they are also called “royal jewelers” or “emperors.”

In this article, we will cover Crowntail Betta (Betta splendens) species profile, care, diet, size, appearance, habitat, tankmates, and more.

Bettas are a species of labyrinth fish, which means they have a unique organ called the “labyrinth” organ, a modification of their gills. This allows them to breathe surface air and oxygen from the water.

It is also why bettas can survive in low-oxygenated waters such as small cup sizes containers, vases, and even toilets. This adaptation does not come without a cost. However, bettas must be kept in warm water, or they will go into an inactive state known as “the sleeping sickness,” which is often fatal.

Bettas are naturally only available in the wild in their metallic colors with oblong-shaped bodies and extended fins. The metallic colors are natural and can not change like other fish species.

But in breeding bettas, the colors may be bred with each other to create new color combinations. This makes them such colorful fish; it’s simply selective breeding of the species.

Bettas come in various colors, from blue to orange, red, violet, and white. They are known for their “sunburst” or “strawberry” tail, which is what gives them their common name- “Crowntail Betta.”

The Crowntail Betta fish is a labyrinth fish, meaning they have a unique organ called the labyrinth which allows them to take oxygen from the air at the water’s surface and its gills.

The labyrinth organ allows them to survive in low-oxygenated waters such as small cups, vases, and even toilets. They also come in various shapes and colors, such as blue or orange.

Crowntail Bettas are available in many pet stores across the world. There are two main types of Crowntail Betta fish: wild caught and tank bred. Wild-caught Bettas can suffer from diseases that tank-bred ones may not have experienced due to their different environment, so it is best to avoid them.

Tank-bred Bettas are typically very healthy and have been bred in a controlled environment with specific traits, such as coloration.

Bettas can grow up to three inches long and need at least one gallon of space each. If you plan on having an entire school, it would be best to have between twenty-five and fifty gallons.

Bettas can live up to three years, but this is rare. Most only live for around one year because they are kept in tiny aquariums. A good betta fish’s lifespan is usually considered to be two years.

These fish are quite popular among many fish owners. I’ve seen them for sale at all my local pet stores. They can be kept in regular aquariums with betta fish, not just special fighting fish tanks like previously thought.

You must keep more than one male together, or they will fight to the death (or until you separate them). Females can live with other females or males, not of the same variety. I’ve also heard that crowntail bettas will only attack their reflections, so they fight more often when it’s near feeding time.

Crowntail Betta: Origin

The Betta, or Siamese fighting fish, is an ancient breed. It’s believed that they were initially bred in the rice paddies of Thailand over 2000 years ago. They are nocturnal animals, and people would gather around them to watch their fierce battles!

Crowntail Bettas usually live together in schools with other types of Betta fish. It’s essential to have an even number of males and females, or they will fight, often to the death. They are also called “water tigers” because of their aggressive personalities!

Crowntail Bettas can be kept in regular aquariums, but it is best to keep them in individual tanks due to their unique fins. The most considerable tank size should be twenty gallons, but I recommend ten to keep them happy.

Crowntail Betta: Appearance

The tail is also an essential characteristic of the Betta when breeders select new mutations and bloodlines. The most prized bettas have large, broad tails long enough to touch the fish’s head.

The Crowntail Betta is part of the gourami family, which means they have small scales and pectoral fins (which help them to breathe). Unlike other types, such as the dorsal (top) fin, this fin type is solid and stiff. The male Betta has a round body, while the female has a slimmer one.

Being in the same family as many other fish with similar bodies, bettas have evolved to have their specialization to survive in their environment. The male Betta displays what is called ‘breeding tubercles.’ Small white nodules appear on the male’s pectoral fin rays. This is a sign that the Betta is ready to breed.

Crowntail Betta fins are another thing that needs to be considered when choosing a pet betta fish. There are different kinds of fins, and their use varies between males and females and different species types. Many fins are also used for different things, such as breeding and swimming.

The Crowntail Betta’s tail is an example of a specialized fin that has evolved to look pretty compared to its other relatives. Bettas have delicate fins that they use to swim with, so it’s important not to expose them to currents or strong water movements in the tank.

The body is also an essential factor when choosing a betta fish. Bettas are usually blue or green iridescent colors, but they can also be red or orange. White varieties have no color, and black ones look like any other dark fish.

Crowntail Betta: Color

One of the most striking features of the Betta is its tail. Its unique shape and color make it easy to distinguish from other species. The fish has a large, broad tail that sticks out even when the Betta isn’t swimming, similar to a rooster or peacock.

The Bettas’ tails are covered in powerful rays, which allow them to display their strength, speed, and beauty. The tail is mainly used for procreation. When the male swims near the female, he spreads his fins wide to appear bigger than he is, showing off his beautiful tail in hopes of impressing her.

Crowntail Betta: Lifespan

The Betta’s lifespan varies between three and four years. Females usually live longer than males because they don’t fight as much. The fish is considered very old at one year.

Male bettas are more likely to get sick or develop diseases because of their fighting nature, which can lead to death much earlier than females.

Crowntail Betta: Size & Growth Rate

The Betta grows up to 3 inches long. The females are generally smaller than the males because they don’t fight as much. The male also has longer fins and tails because he uses them for fighting.

Crowntail Betta: Behavior

Bettas don’t sleep, but they do rest. You can tell if a betta is stressed out (when kept in small containers for too long, forced to breed, etc.) since they’ll appear flat and be at the bottom of the tank.

They also do not require very strong or bright lights, so you should only use the bare minimum for your betta fish.

When you’re ready to feed your betta fish, it’s best not to dump the food in one place since they might eat it all at once and get sick or overweight, which can ultimately kill them. Instead of manually feeding them, try using a small jar with holes in the lid to release the food slowly.

This way, they will eat the food gradually, which is healthier. You should also avoid feeding live fish or feeder fish to your Betta since this can make them sick and give their immune system a hard time.

As betta fish are tropical fish, it’s best to keep them at room temperature (75-82 degrees) and not in the fridge like other fish.

If you plan to put your betta fish in a tank by themselves, don’t be surprised if they start fighting each other one day, which is why you should keep two or more females(or even one male and one female) in the same tank together.

You should also avoid using sharp decorations, which can lead to deadly injuries or death.

Since betta fish are solitary creatures, they’re not often found in schools unless they’re being sold as pets.

Bettas can follow moving objects since they have good eyesight, which is why it’s best to keep them away from other animals or objects that might hurt them.

You’ll want to keep your pet betta as stress-free as possible, so you should give them space to swim around.

Make sure you move them slowly when shifting their location since they may get scared and try to attack the object moving towards them or jump out of the tank if startled enough.

If there are other fish in your tank, keeping a minimum distance of about 3-6 inches between them is best since betta fish will significantly reduce the risk of bullying from other fish.

Crowntail Betta: Sexing

It’s hard to tell the differences between male and female betta fish since they have the same color and shape.

The only way you can distinguish them is through their fins, which may be a bit more rounded if it’s a male, but if it seems thinner with pointed tips, it’s most likely a female betta.

You can also look at their body shape since the male may seem broader, whereas the female Betta will be thinner and taller.

Crowntail Betta: Breeding & Propagation

Crowntail bettas can also be very aggressive, which makes them difficult to breed. Their eggs are not adhesive, which means they will not stick to plants or anything in your tank, so if you want crown tails to reproduce, you must separate the male and female betta once it’s time for them to mate.

The eggs will hatch within three days, and the fry will need to be fed tiny foods such as baby brine shrimp, micro worms, etc. Smaller fish may be food for the more giant bettas, as their big fins can sometimes get in the way of other fish (if they’re not careful).

The female Betta may release stress hormones which may cause the male Betta’s fins to become ragged. This can also happen if you move or touch the female Betta too much after mating. When this happens, give the male and female bettas time to relax and heal/regenerate their fins.

If you want to breed bettas, be sure your tank is at least 7.5 gallons since that’s what’s needed for a male and female betta to live comfortably in separate tanks after mating before releasing the fry.

Once the fry is born, ensure you have a way of taking care of them, such as a small tank or a jar with small holes in the lid to provide fresh air. Some people recommend using jars since it’s easier to clean than other tanks, which is why I’m using them now too.

You’ll need at least 5 gallons for one betta fish, 7.5-10 gallons for two bettas, 15 gallons for 3-5 betas, and so on. Just make sure that there’s no more than one male Betta in the same tank since they’re known to be very aggressive towards other bettas of any gender, which can lead to injuries or death!

Crowntail Betta: Gestation Period & Pregnancy

Breeding betta fish isn’t always easy, which is why most people prefer to buy baby bettas instead of taking the risk of having them die.

The gestation period for a female betta is usually around 21-30 days. During this time, it’s best to keep the female with an open top so fresh air can get in.

The female Betta may become very aggressive towards other fish during this time since she’s protecting her young, so you should take out any other fish who don’t get along with the pregnant fish.

As for water changes, it’s best to change about 20-30% of the tank’s water every 1-2 weeks. You may also want to use a water conditioner to remove any chemicals that might have been used on the betta fish. This will make sure that your Betta does not get sick.

Just be sure that you don’t overfeed the pregnant female since this can cause problems with the fry, too, so you should stop feeding her at least 2-3 days before she gives birth to the fry. She may eat less food if you don’t feed her during gestation, which is another way of knowing when she’s ready to give birth (she may skip feeding for multiple days).

For the male Betta, sexual maturity begins when they’re about 2-4 months old, while the female can be mature after six months.

Crowntail Betta: Food & Diet

Feed your Betta once a day instead of multiple times to keep the water quality high since overfeeding is bad for bettas.

Crowntail Betta: Food

You must feed your Betta small amounts of food throughout the day. Bettas eat all types of tropical fish food. Bettas are carnivores, so they should be fed meaty foods like brine shrimp, bloodworms, or daphnia.

They can also eat freeze-dried betta food since it’s easy to digest. Also, flakes can be given. Using a betta pellet food and crushing it down so the Betta can eat it since they don’t have teeth is recommended.

Crowntail Betta: Diet

Bettas should not be fed more than once or twice daily to prevent bloating. Feeding them too much food will also increase their waste output which can cause water problems. They should be fed at least 3-4 times daily to keep them healthy.

Bettas are carnivores that eat meaty foods such as bloodworms and brine shrimp. They should also be fed flakes, pellets, live food, frozen food, and vegetables for a healthy diet. Bettas cannot survive on flake food alone because it lacks the necessary nutrients they need to survive. Giving them a mix of everything is best for the best results.

Crowntail Betta: Feeding The Fry

To feed them, you can use a turkey baster and put some betta fish food in a cup of water that’s been boiled for a few minutes. Then, you want to spray the food into the tank so the fry can eat it.

Be careful when feeding them because betta fish can be very aggressive and will try and attack your fingers (they only do this if they think food is nearby). You also don’t want to raise any of them since bettas are very protective parents and will try and eat any of their fries that they think is sick or weak.

After a week, you can put some of the female Betta’s fins in a jar filled with tank water to see if she is a good mother (if there is fry inside of it, then she’s a good mother).

You can sell the betta fish since they are trendy pets. Or, give them to family or friends with pet bettas so they don’t become too crowded.

Crowntail Betta: Care Guide

The Crowntail Betta fish originates from Thailand, where they were first discovered in the year 1846 by a man named Theodor Cantor. They were brought to Germany in 1927 and bred for fighting in Thailand ten years later. Bettas are initially from Thailand, but they are now bred worldwide.

Caring for Crowntail Betta is relatively simple; they live in shallow water, making them easy to feed and care for. Owners need full-spectrum lighting on their tanks (for longer life), are fine without a filter (if the tank is small enough for weekly water changes), and do not need mates.

Crowntail Betta: Caring For The Fry

When it’s time for her to give birth, you’ll have about 5-7 days to prepare before she releases all her fries into your tank. This is why you should ensure that your betta fish tank has an air pump and air stones during this time to provide oxygen for the fry.

During this time, you should remove any other fish that can eat or bully the fry since bettas are very protective parents, which means they will do anything to ensure their fry survives (even if it means eating them).

You should remove anything significant (such as decorations) from the tank to ensure that no one accidentally swallows any fry or steps on them.

Keeping Them In A Bowl With Fish Food

No. Bettas need a large tank with heaters and vigorous aeration since they’re nocturnal and like to swim around instead of staying in one place all the time.

They can be kept in a bowl with fish food, but you should change their water daily and feed them at night when they’re the most active.

No, bettas are very easy to care for because they don’t need large tanks and can live with other fish. You must be careful of bettas jumping out of their tanks, so make sure your tank lids fit tightly and securely. You must also change their water frequently and feed them at night when they’re the most active.

Crowntail Betta: Tank Size

Crowntail Bettas can be kept in regular aquariums that contain other types of fish (not just bettas), with a gallon of water for each Crowntail Betta. I recommend 10 gallons of water per Betta, especially if you have a larger tank.

Crowntail Betta can live in smaller tanks but must have more frequent water changes since they generate a lot of waste.

Crowntail Betta also needs a lot of decorations and plants so that they can feel at home. They are very active fish who like to swim around their tanks instead of staying in one place all the time.

Water Parameters

Bettas are initially from Thailand, which has soft water compared with other parts of the world. I recommend using filtered or bottled water treated with a conditioner to remove chlorine on bettas.

Bettas can be kept in a tank with other fish that don’t nip at their tails or fins, but I recommend keeping them in an all-Betta tank since they will get used to each other.

Bettas should be kept at room temperature because small changes in water temperature can make them sick. It’s best to keep them warmer than colder for this reason.

Water Temperature

Bettas should be kept at room temperature (75°-80° F) because small changes in water temperature can make them sick. They’re happiest when kept with other bettas, but they can also survive as single fish.

pH level

The pH level should be the same as other types of fish in an aquarium, but I recommend testing it to make sure.

You should test your water for ammonia, nitrites, and nitrates at least once a week (more frequently if you have more than one Betta in the tank). You may want to quarantine sick fish or new additions like plants in a hospital tank to ensure they don’t spread their sickness.

Filtration

Betta Fish are known for their fighting abilities, but it doesn’t mean they can’t live peacefully with other fish. Certain fish species will get along with bettas, and others won’t. If you want to be safe, keep them alone in a male or female tank where they can’t see each other.

Lighting

Bettas prefer dimmer lighting. They do not need a particular type of light to thrive, but you should leave the lights on in your fish tank for 12 hours and off for 12 hours, just like many other types of fish.

Heater

Bettas prefer a heater that keeps the water at 75° F or warmer. Bettas are from Thailand, which is hotter than other parts of the world, but you should let them choose their temperature because they may be more relaxed if there’s no heater installed.

Filter

You don’t have to have a filter in your betta tank, but I recommend it since it can keep the tank clean and provide better filtration. The only downside is that bettas like to rest sometimes in the vents of filters, so you need a tiny filter for a 1-gallon tank or something more significant for larger tanks.

It’s best to use a filter designed for bettas instead of the filters commonly installed on tanks because they do not produce as much oxygen as other types of fish. Bettas need 5x-6x more oxygen than other types of fish, so you should ensure enough aeration in their tank.

Placement of The Fish

Bettas should be kept in a cool, dimly lit room. Routine and tank time will calm your Betta and make it happier.

Swimming Level

Bettas can swim at different levels in their tanks. They usually prefer to stay near the bottom if they have a dark-colored tank but towards the top if they have a lighter-colored tank, because there’s more light.

You should hear your betta tank bubbling at night when they’re most active. If you don’t, the filter might not be powerful enough for a betta tank because bettas need a lot of oxygen to thrive.

Ways to Put in Water Conditioner

There are many ways to put in a water conditioner, but the easiest way is to pour it into a cup and your betta tank. You can also use a turkey baster for this step if you prefer that method.

What Water Conditioner to Use?

It would help to use only a water conditioner made especially for bettas. Bettas have a particular slime coat that protects them from pollutants in the water, and using the wrong kind of conditioner will strip away this slime coating. The best betta water conditioners are Stress Coat or Seachem Prime.

Crowntail Betta: Tank Region

They are very active fish who like to swim around their tanks instead of staying in one place all the time. Nocturnal – Bettas sleep during the day and actively swim at night when it’s dark. This is why you should only feed them when they’re awake at night.

Bettas enjoy decorating their tanks with plants and other live or plastic decorations since they like to swim around them instead of staying in one place all the time, even though they might always stay near heaters that give off heat.

Bettas also need a lot of aeration in their tanks so that there’s enough oxygen in the water for them to breathe.

Bettas are straightforward to care for because they don’t need a large tank and can live with other fish. You must be careful of bettas jumping out of their tanks, so make sure your tank lids fit tightly and securely.

You must also change their water frequently and feed them at night when they’re the most active.

Crowntail Betta: Tank Decorations

The more decorations and plants, the better! Bettas love to swim around plants, plants make them feel safe, and they hide in plants if they are scared. I would also suggest floating plants since bettas like to swim under them sometimes.

Crowntail Betta: Water Changes

You should change the water in your betta fish tank every 1-2 weeks. You can use tap water that has been treated to remove chlorine, but you should treat it with conditioner for bettas to eliminate other harmful chemicals.

It would help if you also put in a water conditioner when you fill your tank since the tap isn’t treated with anything. Keeping your Betta’s water clean is very important.

The fish can get sick and die if it isn’t done correctly. Bettas like to eat these days (just like their owners), so while you’re feeding them, it’s also a good time to do a 30% or 40% water change depending on the tank size.

The best way to tell when the water needs changing is by using a test kit. This item will measure the tank’s pH, ammonia, and nitrite levels. If you don’t have a test kit (most pet stores will sell them or at least know where to find one), wait until the fish starts acting differently: for example, there might be less movement, or the fish may seem sluggish.

You should also clean out the tank more often if sick fish, new fish, plants that need uprooting, uneaten food floating around, or discolored water (caused by uneaten food).

Things To Avoid When Keeping Crowntail Betta

Adds too many fish to the tank
Sudden changes in weather (like when you move houses)
Leaving an external filter running without a sponge or cartridge
Keeping sharp objects in the tank
Not making sure that the Crowntail Betta’s water has Nitrogen zero levels(like when using unfiltered tap water)
Feeding them any mammal meat (they’re vegetarians!)
You are using soap when washing your hands after touching your fishy friend.
Store-bought Crowntail Betta fish are often beaten with a wooden stick to make them flare up, which is why you mustn’t overfeed your pet since this will only contribute to their poor health.

Remember, Bettas aren’t for everyone, so research before you get your own!

Crowntail Betta: Potential Diseases

Fish diseases can be caused by dirty water, overfeeding, and too much noise. All of these things can make your Crowntail Betta fish sick. If you notice any changes in their behavior, such as hiding under plants or lying at the bottom of the tank, they might have a disease that needs to be treated immediately.

If you notice any changes in their behavior, such as hiding under plants or lying at the bottom of the tank, they might have a disease that needs to be treated immediately. If your Crowntail Betta gets a disease, visit your local pet store to ask for the best treatment.

Sometimes you have to put more than one treatment in their water to kill all the bacteria, so it’s always better to be safe than sorry.

There are a few fish diseases Crowntail Betta can contract. The most common is ich which causes white spots on the body from other infected fish releasing chemicals into the water. Fin rot is another prevalent betta disease that causes their fins to deteriorate for no apparent reason.

Some of the diseases are as follows:

Ich: This is a common betta fish disease that causes white spots to appear all over the body of the Betta. The best way to treat it is to use an ich medicine from your local pet store.
Fin rot: This disease causes the fins of the Betta to deteriorate for no apparent reason and can be fatal if left untreated. The best way to treat it is to use a fin rot medicine from your local pet store.
Pop Eye: This disease causes the eyes of the Betta to bulge out and can be treated by using Epsom salt in their water for two weeks or treating with an eye ointment from your local pet store.
Cloudy eye: This is a common symptom of the pop eye, where the Betta’s eye has a dirty look and can’t be treated by putting Epsom salt in their water or with an ointment from your local pet store.
Fin rot: This disease causes the fins of the Betta to deteriorate for no apparent reason and can be fatal if left untreated. The best way to treat it is to use a fin rot medicine from your local pet store.
Fungus: This disease causes cottony white spots all over the Betta’s body, fins, and mouth. It can be treated with a fungicide from your local pet store.
Velvet: This is a common betta fish disease caused by a parasite that will cause the Betta to have a slimy feel and can affect their gills, fins, and body. It’s best to use an anti-parasitic medicine from your local pet store to treat this disease.
Dropsy: This disease causes the Betta to swell up, and it’s fatal if not treated immediately. It can be treated by putting Epsom salt in their water for two weeks or using an anti-parasitic medicine from your local pet store.
Mouth rot: This is another prevalent betta fish disease where the Betta’s mouth swells up and can be treated using an anti-parasitic medicine from your local pet store.
Swim bladder: This disease makes the betta fish unable to swim correctly, and it is caused by a poor diet, overfeeding, bad water conditions, or other diseases the Betta has contracted.

Crowntail Betta: Treatment & Medication

Many different medications and treatments can fix your Crowntail Betta’s problems. The most common type of medication is aquarium salt, but some fish medicines contain copper to treat the ich disease.

It’s essential to add the medicine when there aren’t any other fish in the tank because it affects all animals in the water by killing or weakening the bacteria.

If putting more than one treatment in their water, change 25% of the water daily to make sure all the waste is taken out. It’s also best to wear gloves when treating your Betta with medication because it can be passed on to you if put into the water.

When your Betta gets sick, visit your local pet store to ensure he gets the best treatment possible. Treatments for sick bettas include increasing the temperature of the water to 86° Fahrenheit, adding aquarium salt, and changing 25% of the water daily.

Wearing gloves when treating your Betta is recommended because they carry some diseases that can be passed on to you, such as ich.

Crowntail Betta Fish are extraordinary pets and will brighten up any room! They’re not as hard to care for as people think and come in various colors and patterns. Betta Fish can live for years and will be with you through thick and thin, so giving them the proper treatment they need is essential.

Crowntail Betta: Tank Mates

Bettas can be kept with other peaceful fish. I recommend having only one Crowntail Betta per tank because they’re active and like swimming around their tanks instead of staying in the same place.

Some examples of tank mates include:

When getting a Crowntail Betta, ensure the tank has been set up for at least one week with no chemicals in the water. It would help if you also got a small net to move your bettas into their tanks (they don’t like big nets).

It would help if you cycled your tank before adding fish by putting in fish food and letting the filter cycle the tank. After a week, you can add a small amount of Crowntail Betta to your tank and watch them closely for a few weeks to ensure they’re happy.

Advantages Of Having Crowntail Betta In Your Tank:

Crowntail Betta does not require a lot of areas to live in. This is because they are labyrinth fish, meaning they can breathe oxygen from the air and water.
Since these bettas only need such little space, you can house them with other types of fish rather than just bettas.
Crowntail Bettas are very beautiful bettas with their lovely tails, making them good for decorations in your tank/stand/table, or whatever you prefer to call it!
These bettas are very cheap and affordable. They only cost about $3, if not less than that.
They are easy to care for.
Most of the time, these bettas are very beautiful and unique. It’s widespread for them to have long tails with blue on them.
Crowntail Bettas are generally healthy bettas.

Disadvantages Of Having Crowntail Betta In Your Tank:

Just like any other type of Betta, Crowntail Bettas can be aggressive.
Crowntail Betta is known to have fin rot and other diseases that can be contracted by any other betta.
Since they only need a little living space, they may not get enough room from their other tankmates, which could cause them to injure themselves or become stressed, especially if they don’t have the correct equipment.
Sometimes, it’s impossible to find a crown tail betta fish that is healthy and safe to keep in your tank, which means you might end up spending money on buying medications and other supplies to make sure that your Betta doesn’t get sick and buy the necessary equipment such as test kits (they’re not very expensive), heater, and tank decoration.
Although they are generally healthy bettas, it’s possible for them to get sick and die just like any other fish, so you must be willing to spend the time and money taking care of your bettas.
Keeping a crown tail betta diseased might result in the other tankmates getting sick as well.
They need to be fed 3-5 times a day, and if they don’t get what they want, they may become hungry and try to attack their other tankmates for food.
If you do not have any equipment to take care of your Betta, you might end up with a dead fish.
The Crowntail Betta fish requires more space than most other types. Unless you have at least 8-10 gallons per Betta, then they will not be happy living in that space. Like any other fish, this type needs to live in clean water, so it should have a filter and a heater.
Like any other type of Betta, Crowntail Betta fish can be very aggressive and sometimes kill their tankmates by chasing them around until the poor victim dies from stress or injuries!

Conclusion

If you’re planning to purchase a crown tail betta for yourself, remember that they’re not easy to take care of and require some special equipment. They are generally healthy, but it’s possible for them to get sick just like any other fish, so it’s necessary to be able to diagnose and treat their illnesses.

If you’re thinking about owning one, consider buying equipment such as test kits, filters, and heaters because these items are important to ensure that your fish lives a long and healthy life.

You should also try asking around if anyone knows good places to buy crown tails because buying a betta that is already healthy and ready to live with other fish (which means you don’t have to spend money on medications and other supplies to make them healthy and perfect for your tank) is a good idea.

Please do the responsible thing and research this type of fish thoroughly before purchasing one! It will not be fun if you get it home, only for your Betta to end up dying due to lack of information.
