Betta fish are beloved companions for many aquarium enthusiasts. They are known throughout the fish hobby for their delicacy and vibrant colors. But have you ever wondered how long these beautiful creatures can live in captivity?
Understanding the lifespan of betta fish helps pet owners prepare for the commitment involved. Knowing their lifespan also enables betta lovers to plan for their future needs, such as tank upgrades, accessory management, and potential medical care.
Striving to enhance the lifespan of betta fish ultimately enables you to provide appropriate care throughout the different stages of their lives. Otherwise, the sadness after their death can compel you to leave the hobby or pause in caring for bettas.
How Long Do Betta Fish Live?
The lifespan of betta fish is a widely debated topic in the betta community. There is no exact answer to how long they live, as several factors must be considered. On average, betta fish live for 2-4 years in captivity, with three (3) years being the most realistic based on the experiences of betta owners. However, bettas can live up to 5 years or even longer with proper care and ideal conditions. Some owners have successfully kept their bettas alive for 8 or 9 years. However, as mentioned earlier, several factors contribute to their longevity. Betta fish, with good genetics and attentive care, can easily live up to 5 years.
It is important to note that betta fish are already 6-12 months old when acquired from stores, as they are allowed to mature and develop their long fins before being sold.
Betta’s Lifespan in Wild
In the wild, betta fish usually only live for 2-3 years due to the fluctuating environmental conditions in their natural habitats. They may face significant challenges in adapting to these changes. These sudden environmental shifts, like drops in temperature during cold weather, can halt their metabolism and lead to premature death. However, we can carefully control their environment in captivity to maximize their lifespan.
Reasons Behind Shorter Lifespan
Reports suggest that betta fish can live for close to a decade, but this is very uncommon. Some betta owners claim to have kept their bettas alive for 7 or 8 years, while others struggle to keep them for 2-3 years despite providing extreme care. There are several reasons behind their shorter lifespan, but let’s discuss some core reasons that are beyond the control of the betta owner.
1. Genetics
The main reason behind their shorter lifespan is their genetics. Some betta fish may have a genetic predisposition to certain health issues or shorter lifespans. For example, a blue betta is more likely to suffer from a tumor than other bettas. Similarly, female plakat are known for their robustness and longer lifespan compared to longer-tailed bettas. I once had a female plakat who lived to the ripe old age of 5, while a veil-tail male with longer fins barely lived for two years.
2. Unethical breeding
Unfortunately, bettas are often overbred, leading to unavoidable underlying health issues. Breeders often resort to unethical practices to achieve specific physical traits, which worsen the condition of bettas. Most of the time, breeders prioritize certain aesthetic traits over health traits, resulting in bettas with weaker immune systems. I once had a rose-tail betta that had been bred for extravagant, ruffled fins, but it later had difficulty swimming, which ultimately resulted in its earlier death.
Tips for Extending Your Betta’s Lifespan
Aquatic creatures, in general, are considered hard to keep alive because they require a life-support environment, unlike other pets. Bettas, specifically, are among the most difficult to keep alive due to their sensitive behavior and susceptibility to diseases. However, with proper care from the start, they are relatively easy to keep alive. How can you ensure your betta lives as long as possible? It comes down to many factors, which we discuss below.
1. Select Your Fish Wisely
When buying fish, I prioritize choosing reputable breeders and pet stores. Many store owners selectively breed bettas, which can lead to shorter lifespans. Therefore, I always look for bettas that are naturally bred and show no signs of weakness or illness, such as damaged fins or discoloration. It’s important to consider the betta’s genetics when making a purchase, as some fish have genetically shorter lifespans.
2. Choose Adequate Tank Size
Acquire a tank that is large enough to replicate the betta fish’s natural habitat. It is recommended to start with at least a 5-gallon tank, as anything smaller will not provide enough space for the fish to swim and explore comfortably. Remember, the larger the tank, the happier the betta fish will be. Therefore, if your budget and space permit, it’s best to choose a larger tank. To choose right tank size, go through our complete article so that you have a better understanding of the betta tank size.
3. Use High Water Quality
Betta fish are very sensitive to water conditions. High levels of ammonia, nitrites, and nitrates in water can stress the betta and reduce its lifespan. To ensure water quality, set up the tank properly and include all essential accessories such as a filter, light, heater, and thermometer.
Maintain a temperature between 78° and 82°F and a pH between 6.5 to 8. The water should be dechlorinated, tested for pathogens, and metal-free. Never use tap water that hasn’t been conditioned for betta fish. Make sure to use a water conditioner to completely remove chlorine, chloramine, and heavy metals from tap water. This will guarantee that the water is safe for your betta fish. Additionally, partial water changes (20-25%) should be performed weekly.
4. Feed Balanced Diet
A balanced diet rich in nutrients ensures that bettas live longer. Make sure to feed your betta a diverse diet consisting of high-quality betta pellets. In addition to regular fish food, you can also feed your fish frozen or live foods like brine shrimp, bloodworms, and daphnia. Avoid them feeding fatty foods and instead provide protein-rich options, as bettas are carnivores. Avoid overfeeding; give only as much food as the size of their eye since their stomachs are about that size.

5. Add Decorations
Betta fish are natural explorers, and they enjoy interacting with their environment. To replicate their natural habitat, you can add decorations such as live or artificial plants, rocks, caves, and shells. This helps reduce their stress and keep them happy and engaged, potentially leading to a longer lifespan.
Fun Fact
I had a betta fish that lived for seven (7) years. To ensure its comfort, I arranged a significant hiding spot in the tank in the form of a large shell. I always put the shell back in the tank, even if it seemed out of place because the betta used it as a den to hide inside and would swim out whenever it saw me.
6. Monitor Health
Keep a close watch on your betta for any signs of illness, like changes in behavior, appetite, or appearance. Betta fish can get different diseases, such as fin and tail rot, dropsy, velvet, ich, and. It’s important to quickly identify and treat any issues to prevent them from becoming life-threatening. Adding Indian almond leaves to the tank can help prevent diseases by providing antibacterial properties.
Signs of Betta Fish Before Death
Even though betta fish can be resilient, it’s important to acknowledge that you will have to part ways with your beloved companion one day. Addressing the signs of betta fish before death is essential, as bidding farewell to a long-time companion can be challenging. Below, you’ll find the most prevalent signs that your betta fish may display as it nears the end of its life.
- Lethargy
- Fading color
- Hunched back
- Laying Down
- Frequent breathing
- Decreased appetite
- Slower Reaction
If you notice any of the symptoms mentioned above, do not leave your pet to suffer; instead, provide immediate care and seek advice from a nearby veterinarian.
Frequently Asked Questions
-
How long do male or female betta fish live?
Gender doesn’t affect lifespan, but female bettas tend to live longer than male bettas. This is because female bettas usually have shorter fins, which are less likely to tear and become infected, reducing their risk of health issues. However, it’s important to note that the lifespan of betta fish can be influenced by many factors, so this isn’t an absolute rule.
-
How long can a betta fish go without food?
Bettas can survive up to a week without food and, if necessary, even a few days beyond that. It’s a good idea to give them a special treat, such as frozen-thawed bloodworms, before and after fasting.
-
How long can a betta fish live in a fish bowl?
A betta fish can live in a fish bowl for a limited time, typically a few months to a year, depending on various factors such as water quality, temperature, and the level of care provided. However, bowls are not the ideal habitats for betta fish, so we will never recommend keeping bettas in them. If your budget and space constraints do not allow for the most recommended size tank, which is a 5-gallon, it is better to acquire a 3-gallon tank, as it is far better than a bowl.
