Fighter fish, also known as Betta or Betta splendens, is one of the most colourful, vibrant and remarkable freshwater fish in the world. A favourite fish among both beginner and experienced aquarium enthusiasts, Bettas are known for their bright, beautiful colour and spectacular fins. But don’t be fooled by their good looks — these little warriors still require some tender loving care to flourish.
What Is a Fighter Fish?
Siamese fish, or Betta fish.. Siamese fish, or Betta fishIt is light in osphronemidae and comes from the low-lying waters of the country, Kampuckea, Vietnam and the Yatland. They are well known for their aggressive behaviour, particularly between males who have been reported to fight each other to the death if kept in the same tank.
The Betta splendens scientific name translates to “splendid warrior”, appropriate considering their fierce and stylish appearance. Many colours of Betta are available, such as bright blue, all shades of red, pale pink and even green or silvery shades – they are often likened to living art.
Betta males are more showy and aggressive, while females tend to be a bit smaller and have shorter fins and less vibrant colours. However, females can still be very beautiful and active, so they are a great option for sorority tanks if you choose to go that route.
Fighter Fish Behaviour and Temperament
The thing that makes them the most interesting, though, is their behaviourr. Although they’re loners by nature, they’re incredibly interactive with humans. Betta enthusiasts have even taught their fish tricks such as swimming through hoops or following a finger along the glass.
Bettas are not community fish as we know them, however. Males should be housed singly, for they are highly territorial and will not only fight with other males, but also apply aggression towards like stripes fish as well. A pair or group of females boldly living and working together in a large, heavily planted tank is a “Betta sorority.” It’s doable — occasionally less so with two females, more generally so with a larger group — but it requires careful consideration,and planning.
Fighter fish are also popular for their labyrinth organ, which permits them to breathe air from the surface. This also means they can live in low-oxygen environments, but they still require a clean and well-maintained tank to be healthy.
A happy Betta has:
- Active swimming
- Bright coloration
- Bubble nests (especially from males)
- Regular eating habits
Alternatively, a stressed Betta can appear to be clamped, have dull colour and be lethargic.
Tank Setup for Fighter Fish
There’s a huge myth that fighter fish can survive in water-filled bowls without heaters or filters, but many people are now starting to realise that this is not true. They are sturdy fish, but betta fish need good tank conditions in order to thrive.
Minimum Tank Size
A single Betta should have no less than a 5-gallon (19-litre) tank. The more room the better, especially if you want to add in some plants or tank mates (for female Bettas only).
Temperature & Water Conditions
Bettas are tropical fish and prefer water temperatures between 76°F and 82°F (24°C–28°C). You will need a small heater to keep the temperature constant.
They prefer pH 6.5-7.5 and water hardness of 5-20 dGH. Weekly water changes (25-30%) are recommended to ensure clean water and to reduce the threat of disease.
Filtration & Aeration
Low-Flow Filter Though Bettas are labyrinth breathers, you’ll still need a low-flow filter to get rid of debris and keep water clean. Billows of current can stress them out, so either use a filter that’s already meant for Betta tanks or add a baffle to take down the flow.
Decor & Plants
Bettas enjoy dark places and are low-light fishes. Tropical silk plants, such as smooth rocks, caves, and driftwood. Live plants such as Java Fern, Anubias, and Amazon swords not only add to the beauty in the tank but also aid in oxygen exchange and reduction of stress.
Feeding Your Fighter Fish
In the wild, Betta fish are omnivorous, so they are meat-eaters and will naturally eat a protein-based diet. In the wild, they eat insects and larvae. When in captivity, a mix of dried Betta pellets, frozen food and a rare live treat keeps them looking good.
Ideal Betta Diet Includes:
- Betta-specific pellets
- Frozen or freeze-dried bloodworms
- Daphnia
- Brine shrimp
- Mysis shrimp
Feed your Betta once or twice daily. Give them only what they can eat in 120 seconds. Overfeeding can cause bloating and water pollution, and both these things may provoke diseases.
You can also add a “fasting day” a week to aid digestion and help prevent constipation.
Breeding Fighter Fish
Like other species, breeding Bettas is interesting but challenging, and is typically not for the beginner. Male Betta’s create bubble nests on the water’s surface to entice females into them. The male only has to arrive before a female lays her eggs, and she will do the rest.ContainerGap After a female lays her eggs, the male fertilises them and stands guard over them aggressively until they hatch.
Basic Breeding Setup:
- Separate breeding tank (5–10 gallons)
- Warm water (around 80°F)
- Live plants/styrofoam cup for bubble nest
- The female is added only when the male is in condition.
The female must be removed straight after spawning to avoid fighting. The male will then incubate the eggs until they hatch, which usually happens in 24 to 36 hours. When the fry become free-swimming, the male should also be removed.
Betta fry raise Offspring in the form of Infusoria/larvae (or liquid fry food at first), then hatch baby brine shrimp as they develop.
FAQs
Do two betta fish get along?
No – Betta fish males are far too aggressive and should not be placed with another male, naked or not. Female Bettas can also be kept in a sorority tank, provided the tank is big (at least 20 gallons) and densely planted so that aggression can be dissipated.
How long do Betta fish live?
With good care, Betta fish can live for 3 to 5 years, or even longer. They do best with clean water, a varied diet, and a low-stress environment.
Do Betta fish need a filter and a heater?
Yes. Contrary to popular belief, Betta fish DO live longer with a filter and heater. They are tropical fish requiring a constant warm temperature and clean water to remain healthy.
My Betta is blowing Bubbles?
Happy or breeding-ready, male Bettas create bubble nests. It’s a natural activity andan indication that your fish is comfortable in its surroundings.
Do Betta Fish Get Along with Other Fish?
Whether or not bettas can live with others is all about their level of aggression. Corydoras catfish, Kuhli loaches, or snails are typical bottom dwellers that should peacefully coexist with Bettas, but always observe for aggression.
Conclusion
Fighter fish are charming little guys that mix beauty with a cool view effect. With proper attention, environment, and care, your Betta can flourish and be a beautiful addition to your aquarium. Their bright colours, outgoing behaviour, and unique character make them one of the most rewarding freshwater fish to own. So, whether you’re a beginner hobbyist or an experienced fish keeper, caring for a fighter fish is a rewarding adventure that is worth every second.
