What is the Oldest Betta Fish? | pet igloo (2023)

In this post, we answer the question "What is the oldest betta fish?". We will also list and discuss some actions you can take to extend the life of your betta fish.

What is the Oldest Betta Fish?

The oldest betta fish is believed to live to be about 10 years old. However, there is no scientific record of the actual age of this betta fish.

How long do normal betta fish live?

There is currently no established method of extending a betta fish's lifespan. Betta fish, also known as hepatic lipidosis, are prone to fatty liver disease. There are several symptoms, including a pale look, rotting points, cloudy vision, skin rashes, and a lack of movement.

Providing clean, filtered water is an excellent method to avoid this situation. Maintain a routine for your betta fish's diet. No matter how nutritious your diet is, you should avoid eating too much or too little at any time of the day.

It takes an average of three years for a betta fish to reach maturity. However, with proper nutrition, plenty of clean water, and sanitary conditions, you can significantly extend the life of a betta fish. Still, a betta fish has a longer lifespan - it can live up to 5 years.

It is quite unusual for a betta fish to live more than 5 to 10 years. Betta fish can live up to 9 or 10 years in captivity under controlled environmental conditions and away from other species that are considered very long-lived.

How long do betta fish usually live in tanks?

Just because you can expect to keep your fish for three years doesn't mean you should buy your fish right away. Male Betta fish are usually not available for sale in pet stores until they are about a year old. This is the stage where their colors and ends have fully formed. Females are sold a little earlier than males, usually around 6 months of age.

While females tend to survive a few months longer than males, many prefer to keep males because of their beautiful colors. Since your fish is normally 6 months to 1 year old by the time you buy it, you can expect it to survive about two to two and a half years after purchase.

Bettas, on the other hand, can survive up to 4 or 5 years if provided with ideal tank conditions and properly cared for and fed (more on this later).

How long do betta fish live in their natural habitat?

Bettas are found in shallow freshwater environments such as ponds, streams, paddy fields and canals in the wild. Due to human introduction, they have spread to other regions including Singapore, Brazil and Malaysia, where they were previously only found in Cambodia and Thailand.

Betta Fish in the wild are believed to have a slightly shorter lifespan than those kept in captivity, according to many people. Due to the fact that the water they live in is not managed as carefully as the water in an aquarium, they can become contaminated, which can kill food sources and plants, significantly shortening the fish's lifespan.

Males in the wild are also more likely to be exposed to other males than to females. Siamese fighting fish are so named because they are extremely territorial and violent towards other fish that invade their territory.

Increased exposure to other evils increases their chance of fighting, increasing their chance of dying sooner.

How do you extend the life of your betta?

After understanding how long betta fish live in tanks and in the natural habitat, we can start thinking about how we do thatprolong their lives as long as possible. In reality, it's quite simple, and by following all the recommendations below, you'll increase their chances of living longer while improving the overall quality of their existence.

Make sure you buy a healthy betta

Buy your fish from a well-known retailer. Avoid buying fish that display any of the following characteristics - these characteristics may indicate that the fish has not been properly cared for, and as a result they may be stressed and less likely to live long.

· Pale color

Torn fins

· Bulging eyes

· Injuries or scars on their body

You should be looking for a fish that is one of the following:

· Bright colour

Own bright clear eyes

· Have reflective behavior

Use a filter and a heater

It is a popular misconception that because Betta Fish live in the wild in rice paddies, they can tolerate unheated, dirty water. This is not true.

Due to the environment in Thailand, the water in your tank will naturally heat up, making it necessary to install a heater in your tank as well. They are used to temperatures ranging from 75 to 80 degrees Fahrenheit.

It is also necessary to use a filter. They will not survive in water that is contaminated or unfiltered. A filter cleans the water by converting the ammonia and nitrite buildup into less dangerous molecules, and it also keeps the water aerated, which is important for swimming.

Even when using a filter, it is still necessary to change the water regularly to prevent nitrate build-up.

Use plants to provide oxygen

The last piece of advice we have for creating the greatest possible habitat for your Betta and, as a result, extending their lifespan is to incorporate plants into your aquarium design.

The benefits of keeping plants in your aquarium are not based on their nutritional value, as with other species. Since these fish are carnivorous, the nibble they get from the plant will be just that: a nibble.

Living plants increase the oxygen content in your aquarium and enrich the environment at the same time. It will also mimic their native environment, increasing the likelihood that you will witness their normal behavior.
