Walking into the pet shop one of the first things that catch your eye is the beautiful siamese fighting fish that are on display. Due to their popularity, there are a lot of questions surrounding betta fish and one of the most commonly asked is “How long will my betta live?” We’ve put together a comprehensive guide on betta lifespan, what effects it has, and tips to prolong your betta’s life.
How long do betta fish live?
The average lifespan of betta fish can range from 2-5 years and is directly related to the environmental conditions of your betta fish tank. Most betta fish live for 3 years after being bought from a local pet store.
Can bettas live for 10 years?
While your betta’s life expectancy is 2-5 years it’s not uncommon for a healthy betta fish to live 6 years, and some have even been known to live up to 10 years (though rare!). A betta fish’s lifespan is directly dependent on the fish’s health when it enters your tank and tank conditions.
How long do betta fish live in the wild?
In their natural habitat betta lifespan tends to only be about 2 years long. This is because they live in a more stressful and aggressive environment that usually doesn’t have fresh water.
How long betta fish live in captivity
How long your betta fish’s life will depend on the environment you keep it in. These are tropical fish and require an aquarium heater, treated tap water, and excellent filtration. One of the leading causes of early death in betta fish is having small tanks for your fish. Many pet stores sell kits for bettas that include a one-gallon tank, when in fact they need a much larger tank.
In a properly sized tank, your betta fish will live a long and happy life, but in a tiny tank, your betta will likely experience poor water quality leading to diseases such as fin rot or swim bladder disorder and early death.
How long do male betta fish live
There is no difference between the female and male betta fish life span, as long as they are placed in similar environments each betta fish will live a healthy life.
How long do female betta fish live
Female bettas live the same length of time as males, but it often seems like they live a few months longer. This is because the pet store will sell male bettas when they’re fully mature (7 months to 1 year) to ensure that their tails have vibrant coloring which usually sells better. On the other hand females are usually sold around 6 months of age.
How long do betta fish live without food
Betta fish can survive for 10 to 12 days without any food, however, that doesn’t mean you should withhold food from your betta fish as this will be detrimental to the betta’s health and lead to starvation. Keep in mind that this estimate is based on the tank having the perfect conditions and having a healthy fish prior to leaving.
What kills betta fish?
The most common cause of early betta death is having a poor environment. Betta fish live longer when the proper water parameters are observed. For example, since bettas are tropical fish the water temperature of your tank should be between 75-80 degrees Fahrenheit. Other causes of a poor tank environment include unclean water, bad tankmates, a small tank, sudden changes, ammonia poisoning, and overfeeding.
Things that affect betta fish lifespan
There are a few factors that can affect your betta’s lifespan, but none so much as a clean tank. Poor environmental conditions are one of the most common causes of death for bettas.
Genetics do play a part in betta’s lifespan, however, to get any information regarding your betta’s genetics you have to buy from a breeder that can tell you the history of their parents.
There is some speculation in the aquarium community that the red and blue veil tail bettas live the longest because they have not been selectively bred as much as other varieties and are closer to their original ancestors.
How old your betta is when you buy it will vary from different sources. If you buy a new fish from a breeder they will likely be able to tell you the exact age of your pet betta fish, if you buy from a store this might be a bit harder. Most stores sell pet fish when they’re between 6 months and 1 year old.
To keep your betta fish healthy you should keep your tank clean and in the best condition possible. This means removing uneaten food, using a water conditioner if you add distilled water or tap water to the tank, and maintaining proper water temperature.
To keep your betta fish happy you should have a minimum tank size of 5 gallons. While they can live in smaller tanks they will not thrive. Your tank should also contain a heater and filtration system as well as an enriching environment containing objects such as plastic plants to encourage stimulation and lead to a long life.
In the wild bettas live in shallow puddles and have developed lung-like organs that allow them to gulp air from the surface. This has earned them the name of labyrinth fish.
If you have baby bettas you can keep them in a 2 or 3-gallon tank (1 per tank!), but watch for aggression, and transfer them to other tanks as soon as any aggression signs appear.
While feeding your betta fish a rich and varied diet will improve their coloring it will also lengthen their lifespan. Ensuring that you are providing proper nutrition and protein through fish food is one of the most important aspects of fish keeping. Betta fish food can come in the form of fresh, frozen, or commercially available options such as brine shrimp, betta pellets, and blood worms.
Keeping other fish in the same tank as your betta fish can be tough, they’re called the fighting fish for a reason! Some freshwater fish that we recommend for tank mates include
- Mystery Snails – great for cleaning up uneaten food and algae in your betta fish tank.
- Ghost Shrimp – an easy-to-care-for and peaceful companion that will clean your tank at the same time.
- Clown Plecos – a peaceful fish that will stay out of your betta’s way as it swims along the bottom and sides of the tank. They have tough skin in case a young betta fish gets curious about their new friends.
- Kuhli Loach – very docile and prone to hiding these fish will stay out of your betta’s way. However, they need a minimum of 20 gallons.
When adding any fish to your tank be sure that you have taken into account the amount of tank space they need.
Diseases that shorten betta fish life
For bacterial infections such as dropsy, fin, and tail rot, and ich you can treat them with anti-bacterial medicine and isolation. Preventive care includes keeping living conditions clean and using aquarium salt.
For parasitic infections treatments such as Bettafix or FishZole are most effective. You should isolate the affected fish to ensure that community members are not infected.
Other diseases such as ammonia poisoning require immediate removal of your betta from the environment and recycling of the tank, while also using Indian almond leaves to treat your betta’s slime coat and soothe the irritation.
You can use aquarium salt as preventive care for your betta but don’t make a habit out of it as it can change your tank pH levels by making them more alkaline (basic) and potentially causing your fish to be stressed and even die.
Fish keeping can be intimidating and comes with a lot of questions, but by following these tips, and providing proper living conditions your betta should have no trouble living a healthy and happy life.
