The King Betta is a subspecies of the Siamese fighting fish. It is also known as the Crown Tail Betta(CTB). The King Betta is native to Thailand and Cambodia. It was first discovered in 1836 by a German naturalist Johann Baptist von Spix.
King Bettas are very popular among aquarium hobbyists due to their unique appearance and relatively docile personality. They are easy to care for and make great beginner fish.
There are two reasons why King Bettas are called "crown tail." The first reason is their long, flowing fins resembling a crown. The second reason is because of the way their tail is shaped. Most bettas have an "imperial" or "double tail."
Their tail fins are split down the middle into two separate lobes. On the other hand, King Bettas have a tail that is only split at the very tips. This gives their tails a "crown" like appearance.
This article will discuss everything you need to know about keeping King Bettas in your aquarium. We will cover diet, housing, tank mates, and more topics.

The scientific name of the King Betta is Betta splendens. The King Betta is a subspecies of the Siamese fighting fish. It is also known as the crown tail betta or CTB. The King Betta is native to Thailand and Cambodia. It was first discovered in 1836 by a German naturalist Johann Baptist von Spix.
They are an 'anabantoid' fish. It can breathe air using a special organ called the 'labyrinth.' The labyrinth is just behind the betta's head, allowing the fish to absorb oxygen. This adaptation allows bettas to live in water that is low in dissolved oxygen.
The King Betta male has a very aggressive and territorial personality. He will often attack and kill other fish. For this reason, it is recommended that King Bettas be kept in a tank by themselves. The King Betta female is not as aggressive as the male, but she should still not be kept with other fish.
The cost of a King Betta can vary depending on where you purchase it. King Bettas are typically sold for $10 to $20. But, if you purchase a King Betta from a breeder, the cost can be much higher.
King Betta Appearance
The King Betta is a beautiful fish with long, flowing fins. The male King Betta is usually more brightly colored than the female. Male King Bettas also have longer fins than females.
The most distinguishing feature of the King Betta is its tail. The tail of a King Betta is split into two lobes. This gives the tail a crown-like appearance, hence the name 'crown tail betta.'
The fins and tails of King Bettas are exceptionally long and beautiful. The fins are so long that they can extend up to twice the length of the body.
They have a long, slender body with large eyes. The body is typically orange, red, or yellow. The fins and tail are usually blue or green. However, King Bettas can also be found in various colors, including white, black, and brown.
The King Betta differs from other bettas in a few ways. The most notable difference is the shape of the tail. Most bettas have a round or oval-shaped tail. However, the King Betta has a split tail that resembles a crown.
King Betta Size & Growth Rate
The size of a King Betta can vary depending on the individual fish. However, most King Bettas grow to be 2 to 2.5 inches long.
The growth rate of a King Betta is relatively fast. King Bettas typically reach their full size within 6 to 8 months.
King Betta Lifespan
The average lifespan of a King Betta is 2 to 3 years. However, King Bettas can live for up to 5 years with proper care.
However, several factors can shorten the lifespan of a King Betta. These include poor water quality, lack of food, and disease.
King Betta Behavior & Temperament
Because the betta is a territorial fish, keeping more than one in the same tank is not recommended. They often fight each other, leading to serious injury or death.
They are also known to be aggressive towards other animals, including fish, frogs, and even turtles. For this reason, it is essential to research the other animals you are considering keeping in your tank before adding a betta.
Bettas are generally peaceful towards humans and make good pets for children. They are also relatively easy to care for, making them a good choice for beginner fish keepers.
King Betta Breeding
Bettas can be bred in captivity, but it is a complex process experienced fish keepers should only attempt.
The female betta will lay many eggs, which the male will then fertilize. The eggs will hatch in about 24-48 hours, and the fry will be free-swimming a few days later.
The fry must be fed live foods, such as brine shrimp or bloodworms, for the first few weeks of their lives. After that, they can be slowly transitioned to pellets or flakes.
If you are interested in breeding bettas, it is important to research and ensure that you are prepared for the process. Several things can go wrong, and preparation for any eventuality is essential.

- Discard the dirty water in a drain or outside.
- Refill the tank with fresh water.
- Add the water conditioner to the fresh water.
- Stir the water to mix in the water conditioner.
- Put the lid back on the tank.
- Enjoy your clean and healthy aquarium!
Cleaning The Tank
In addition to doing regular water changes, you will also need to clean the tank regularly. This includes cleaning the glass, vacuuming the gravel, and cleaning the filter.
- Cleaning the glass: To clean the glass of your aquarium, you can use an algae scraper or a sponge. Be sure to scrape or sponge away all the algae from the glass.
- Vacuuming the gravel: To vacuum the gravel, you must use a gravel vacuum. A gravel vacuum is a tool used to remove debris and waste from the substrate.
To use a gravel vacuum, place the end of the tube into the substrate and suck on the other end. This will create a suction to pull the debris and waste into the tube.
Cleaning The Filter
It is essential to clean the filter regularly. A dirty filter can cause several problems, including poor water quality and unhealthy fish.
To clean the filter, remove it from the tank and disassemble it. Most filters can be disassembled by unscrewing the top. Once the top is off, you can access the filter media.
The filter media is the part of the filter that does the work of filtering the water. There are several different types of filter media, but the most common are Activated Carbon and Bio-Balls.
- Activated Carbon: Activated carbon is charcoal used to remove toxins from the water. It is a very effective filter media, but it needs to be replaced regularly.
- Bio-Balls: Bio-balls are small plastic balls that are filled with bacteria. These bacteria help to break down waste and toxins in the water. Bio-balls need not be replaced as often as activated carbon, but should be cleaned regularly.
To clean the filter media, rinse it in aquarium water. Avoid using soap or detergent, as these can harm the bacteria on the media.
Once the filter media is clean, you can reassemble the filter and put it back in the tank.
Testing The Water
It is essential to test the water regularly. This will help you to keep the water parameters in the correct range.
There are several different ways to test the water. The most common way is to use test strips. Test strips are placed in the water and then compared to a chart that will tell you the levels of different water parameters.
Another way to test the water is to use a digital meter. A digital meter will give you an accurate reading of the water parameters.
The most important water parameters to test are ammonia, nitrites, and nitrates. These are all toxins that can be harmful to your fish.
- Ammonia: Ammonia is produced by the fish and their waste. It is very toxic to fish and can kill them if the levels get too high.
- Nitrites: Nitrites are produced by the bacteria that break down ammonia. They are also very toxic to fish and can kill them if the levels get too high.
- Nitrates: Nitrates are produced by the bacteria that break down nitrites. They are less toxic than ammonia and nitrites but can still harm fish if the levels get too high.
Keeping the levels of these toxins in the correct range is essential to keep the water healthy for your fish. The acceptable ranges will vary depending on the type of fish you have.
You can find the acceptable ranges for different fish species in various sources, including pet stores, aquarium books, and online.
King Betta Common Possible Diseases
Several different diseases can affect fish. Some of the most common are listed below.
- Ich: Ich is a parasitic infection that causes white spots on the fish. It is caused by a protozoan called ichthyophthirius multifiliis. Ich is very contagious and can spread quickly through an aquarium.
It is essential to treat ich as soon as possible. The most common way to treat ich is with a medication that contains the active ingredient metronidazole. This medication can be found in pet stores and online.
- Dropsy: Dropsy is a disease that causes the fish to swell up. A bacterial infection causes it. Dropsy is very contagious and can spread quickly through an aquarium. It is essential to treat dropsy as soon as possible.
The most common way to treat dropsy is with a medication that contains the active ingredient erythromycin. This medication can be found in pet stores and online.
- Fin Rot: Fin rot is a disease that causes the fish's fins to disintegrate. A bacterial infection causes it. Fin rot is very contagious and can spread quickly through an aquarium. It is important to treat fin rot as soon as possible.
The most common way to treat fin rot is with a medication that contains the active ingredient chloramphenicol. This medication can be found in pet stores and online.
The best way to prevent disease is to maintain a clean and healthy environment for your fish. This means keeping the water quality high and the tank clean.
It is also important to quarantine new fish before adding them to the main tank. This will allow you to monitor them for any signs of disease.
If you notice any signs of disease in your fish, treating them as soon as possible is important. The sooner you treat them, the better their chances of recovery.
Treatment And Medications Of Diseases
Several different medications can be used to treat fish diseases. The most common are listed below.
- Metronidazole: Metronidazole is an antibiotic used to treat various infections, including ich, fin rot, and dropsy. It can be found in pet stores and online.
- Erythromycin: This antibiotic can be used to treat infections in bettas. It is available in liquid and tablet form and can be found at most pet stores.
- Chloramphenicol: This antibiotic is no longer used in the aquarium hobby for several reasons. It can be very effective against gram-negative bacteria but is also quite toxic to fish and other aquatic creatures. In addition, chloramphenicol has been linked to aplastic anemia in humans, so it's best to avoid using this medication if
- Tetracycline: Betting KingdomTetracycline is an antibiotic that fights infection caused by bacteria. Tetracycline treats many bacterial infections, such as urinary tract infections, acne, gonorrhea, chlamydia, etc. Tetracycline may also be used for purposes not listed.

- Processed foods: Processed foods, such as chips and crackers, are high in salt and fat and can harm your fish.
King Betta Feeding Schedule
Bettas should be fed once or twice a day. The food they need will depend on their size and activity level. A good rule of thumb is to feed them as much as they can eat in 2-3 minutes.
Overfeeding can lead to health problems like obesity and swim bladder disease. If you are unsure how much to feed your betta, ask a staff member at your local pet store or contact a veterinarian.
King Betta Tank Mates
Because bettas are territorial and aggressive, they should not be kept with other fish. They can, however, be kept with various invertebrates, such as snails, shrimp, and crabs.
It is important to research the compatibility of any potential tank mates before adding them to your tank. Some animals may not do well with bettas, and others may be too small and be eaten by the betta.
Some tankmates that are known to do well with bettas include:
- Cory catfish
