Betta fish usually live for about 2 to 3 years. Some can even live a bit longer if they are cared for.

Like any pet, they need a clean and comfortable home, proper food, and regular check-ups to stay healthy and happy.

If you take good care of your betta fish, it can live a long and happy life in your aquarium.

How Long Do Betta Fish Live Without Food?

Betta fish can survive without food for about 7 to 14 days, but it’s not ideal for their health. Just like us, they need regular meals to stay strong and healthy.

If you’re going to be away, it’s a good idea to ask someone to feed your betta fish or use a vacation feeder.

It’s important not to overfeed them, but consistently providing them with the right amount of food will help keep them happy and healthy.

However, with proper care, some bettas can live a bit longer, even up to 4 or 5 years.

How Long Do Betta Fish Live in the Store?

Betta fish in stores are usually kept for a few months, but their exact time in the store can vary.

The conditions in pet stores may not always be ideal, and bettas can face stress during their time there. They need to be moved to suitable homes as soon as possible.

When you buy a betta from a store, providing it with a proper aquarium setup, good water quality, and a balanced diet will contribute to its well-being and increase the likelihood of a longer and healthier life as your pet.

How Long Do Bettas Live in a Bowl?

Bettas can live around 3-5 years on average in a small bowl, but they live longer and healthier in better homes.

Important things to know about keeping bettas in bowls:

  • Bowls usually don’t have heaters or filters. Bettas do well in water that’s 78-80°F with gentle filtration to mimic their natural homes. Without this, their immune systems are weaker.
  • Bowls need frequent 100% water changes, sometimes every day. This can stress out bettas, and the water quality drops quickly between changes. Larger tanks only need partial water changes 1-2 times per week.
  • Bowls are often too small, less than 1 gallon. This stops bettas from growing properly and doesn’t give them enough space to move around happily. Most experts recommend at least 5 gallons for their health and behavior.
  • Decorations in tiny bowls have to be minimal. Bettas like plants, caves, and much to explore and feel safe.

Are Betta Fish Hard to Keep Alive?

Betta fish are considered to be relatively easy to care for, but like any pet, they do have specific requirements.

Some considerations:

  • Tank Size: Betta fish need a proper-sized tank, ideally a minimum of 5 gallons. 
  • Water Conditions: Betta fish are sensitive to water parameters. It’s crucial to maintain stable water temperature (78-80°F or 25-27°C) and quality. 
  • Proper Diet: Providing a balanced and high-quality diet is essential. 
  • Tank Decor: Bettas benefit from a well-decorated tank with hiding spots and plants. However, decorations should be smooth to avoid damaging their delicate fins.
  • Isolation: Bettas are known for their territorial nature. It’s important to keep them in solitary conditions, especially males, as they can be aggressive toward each other.
  • Tank Maintenance: Regular cleaning and maintenance of the tank, including filter care and substrate cleaning, are crucial for their well-being.
