The noble Siamese fighting fish is one of the most splendid ornamental fish for aquariums.
While the true wild form of the Siamese Fighting Fish is rare to found, its cultivated forms flaunt an array of colours. They are available with long, fluttery fins in numerous hues.
Particularly noteworthy is its labyrinth organ, which enables the fish to absorb oxygen even in oxygen-poor freshwater environments.
While males are very colourful, females tend to have more muted colours. Both sexes reach a size of about four to 16 centimetres.
Biologists categorize the Siamese Fighting Fish into many subspecies, depending on patterns and forms. The classification includes eight main pattern groups, which primarily describe the marking and colouring of scales and fins:
In addition to the patterning, classification also includes tail shape:
However, the majority of Bettas available in pet shops have the distinctive veil tail, with either rectangular or diamond-shaped cuts.

Caring for a Siamese Fighting Fish is straightforward, making it suitable for beginners. Since this colourful fish is relatively small, you need not invest in a very large aquarium.
The aquarium and water should exhibit the following features:
Due to its large fins, the Siamese Fighting Fish requires plenty of energy and space to move around in the water. The ideal temperature is between 24 and 30 degrees Celsius.
Temperatures below 20 degrees Celsius can cause discomfort to the fish; they will likely be less active. You can gently heat the water in a 30L aquarium with a 25-watt heater.
Siamese Fighting Fish do not appreciate fast-flowing water; they prefer still waters like in their natural habitat. Consider this when setting up your aquarium.
Siamese Fighting Fish adore aquatic plants planted at the bottom of the tank. Generally, Asian plants are preferred over European aquarium plants.
They enjoy densely planted areas and smaller floating plants, although space should still be left on the water’s surface for bubble nests.
Although dense plant cover will make the tank appear darker, the fish feel comfortable in this atmosphere. Red-green and white-green marsh plants also provide optimal shade.
For decoration, you can use real stones and wood. You can choose these elements according to your preference, as long as you do not use bright or coloured stones. Whether gravel, rounded pebbles or sand – the choice is yours.
While there are peaceful individuals, the Siamese Fighting Fish can sometimes be unfriendly. They can be very aggressive, which is why you should never house two males together. It is therefore advisable to keep male specimens alone.
With other fish species, it’s important that they are neither too large nor too small. Larger fish may see your Siamese Fighting Fish as prey, while smaller fish might become prey themselves.
Cichlids exhibit similar territorial behaviour, so they’re not great candidates for cohabitation. Guppies are a definite no-go. Danios are not suitable either, as their high activity levels can stress out your Siamese Fighting Fish.
The best tank-mates are catfish and fish of similar size with small fins.
For hygiene reasons, you should always remove food remnants, waste and dirt from the substrate. If not, disease-causing organisms can multiply, leading to serious infections.
The water quality will also suffer if you don’t clean the tank occasionally, impacting the health of your fish.
Regular water changes (about once a week) can negate the need for a filter. However, small internal filters have their advantages; they’re quiet and usually adjustable.
You might also consider using water conditioners, as these clean the water of any possible heavy metals. However, too much can destroy important bacteria that fish need from time to time.
Free-living Siamese Fighting Fish predominantly feed on small soft-bodied animals and insects. Siamese Fighting Fish kept in aquariums are strictly carnivorous. Plant-based fish food is therefore not an option.
You can also purchase special flake food and granules. These should contain ample animal protein, which the fish need for muscle building. Alternatively, you can feed them live food (such as flies, larvae, or mosquitoes).
Many Siamese Fighting Fish owners also offer frozen insects. Small portions of green beans are also generally acceptable.
A Siamese Fighting Fish should be fed regularly. Ideally, feed it once every day.
With an average lifespan of about three to five years, Siamese Fighting Fish do not live very long but are generally healthy and robust fish. Failure to follow recommendations for care and feeding can, however, lead to illness in your fish.
A significant threat includes fungal and bacterial infections. These can be due to underpowered filters. On the other hand, filters can also cause stress, which may lead to diseases and death.
Sound the alarm if your fish is lethargic and stays at the bottom of its tank. This could be a sign that it is ill or stressed. It might also indicate that the water temperature is too low.
If your fish exhibits swollen eyes, half-open gills or other pathological changes, you should seek advice from your vet. You should also isolate sick animals from others.
In contrast, a healthy Betta Fish regularly swims through its territory. It carries its tail and fins stretched out far from its body. Its scales smooth and clean.
Siamese Fighting Fish can suffer from various fish diseases. For example:
The name Siamese Fighting Fish (scientifically Betta) is not without reason. While Siamese Fighting Fish are not dangerous to humans, they are highly aggressive towards other fish and species.
In Thailand, people even hold competitions where aggressive fish fight each other. Such betting contests traditionally do not occur in Europe or America. Instead, they are a popular pet, mainly due to their splendid appearance.
There are exceptions to every rule. For example, Betta imbellis, also known as the Peaceful Fighting Fish, is a cheerful companion.
Thailand is internationally recognized as the home of the Siamese Fighting Fish, mainly due to the traditional fish fights.
However, the term “Betta” indicates that the Siamese Fighting Fish, also known as Betta splendens, is spread elsewhere too.
The word Betta originates from Javanese (Java, Indonesia). In Thai, the fish is more commonly known as Pla-kad or Trey Krem.
The fish species native to Southeast Asia prefers the freshwater bodies of Indonesia and regions around Bali, Malaysia, Laos, Vietnam, Myanmar and Cambodia. Outside Southeast Asia, Siamese Fighting Fish are found only in aquariums or private ponds.

Siamese Fighting Fish are a true classic in pet shops. Often, you’ll find only common varieties with Crown and Halfmoon Tails. To find more unique breeds, you may need to place special orders or look in larger cities.
Another option is the Internet, which offers a very wide selection of Bettas. You can browse at your leisure but will usually need to pick up the animals in person.
A standard specimen may cost around £10 to £20. However, the price varies depending on species, origin, and appearance. Therefore, more popular examples can cost well over £100 each.
Siamese Fighting Fish are suitable for aquaristics novices. It’s crucial that you follow the recommended guidelines for proper care and feeding of your fish. By doing so, you can enjoy the vibrant and delightful company of these fishes in your aquarium for a long time.

At the Justus-Liebig-University of Giessen I was extensively trained as a veterinarian and was able to gain experience in various fields such as small animal, large animal and exotic animal medicine as well as pharmacology, pathology and food hygiene. Since then, I have been working not only as a veterinary author, but also on my scientifically driven dissertation. My goal is to better protect animals from pathogenic bacterial organisms in the future. Besides my veterinary knowledge, I also share my own experiences as a happy dog owner and can thus understand and enlighten fears and problems as well as other important questions about animal health.
